Faster is not always better. Neither is running your cutting tool too slow. In fact, it’s a dance that depends on several variables if you want to get good results like extended tool life, optimum machining time and excellent surface finish. Running a cutting tool too fast can result in tool breakage. Too slow, and it can result in excessive heat and premature cutting edge failure. Other effects that can occur when operating outside of recommended ranges can include build-up edge, cratering, edge wear, chipping, and inferior surface finish.
We came across a survey performed by CNC Cookbook that asked readers, “How do you calculate your feeds and speeds?” These were the top responses:
For the most accurate answers to your cutting tool’s capabilities, your best bet is to check with the manufacturer’s recommendations. There you can learn more about the proper feeds and speeds to run cutting tools like milling cutters. To help you on your way, we’ve gathered the following best practices from a great article over at Modern Machine Shop:
Materials
First and foremost, you need to identify and understand the material to be cut, otherwise known as your workpiece. Steel, cast iron, aluminum, stainless steel, titanium and high temperature alloys all have different properties which impact the efficiency and accuracy of the cutting tools you use. These are referred to as machinability ratings and are expressed by a percentage as defined by the American Iron and Steel Institute.
Cutting Tools
Choosing the right cutting tool is dependent on knowing the material of the workpiece. With regards to milling cutters, face mills, end mills, drills and other cutting tools they all have certain criteria they must follow to ensure optimum performance. The tool’s diameter, the arrangement of cutting inserts, the material removal rate, and the depth and width of the required cut all play a major role in how well your workpiece is machined.
Cutting Speed
Speed rates are also called surface speeds and are measured in Surface Feet per Minute (sfm). This measures how fast a tooth, otherwise known as a flute, will move as it cuts through material. Cutting speeds is the speed difference between the cutting tool and the surface of the workpiece it is cutting. Smaller diameter cutters generally require higher revolutions per minute (rpm) and larger cutters need less rpm to propel the cutting edges at their desired sfm.
Pro Tip: Our friends over at Sandvik Coromant have a great Cutting Speed Calculator that can help you specify the cutting speeds and feeds for your application. Check out the Cutting Speed Calculator here!
Feed Rates
Feed rates are the relative velocity at which the cutter is advanced along the workpiece. In other words, it is the rate the cutter enters into the workpiece. Chip loads are an impact factor to consider here because the better chip removal, the less wear on the cutter and the better result on the workpiece. For example, face mills can often take heavier chip loads than end mills in the same application.
Insert Arrangement
Along with choosing the cutter that can provide optimum feed rates, you should consider how the cutting inserts are arranged. How many effective inserts are in the cutter? How are they arranged? The way these inserts are arranged can have a tremendous impact on feed rates, the required horsepower, and material removal rates.
Remember these are just guidelines; refer to the cutting tool manufacturer for specific formulas and calculations. Often it comes down to trial and error and simply getting to know your machine, your material, and your desired result. However, by following some best practices and becoming more familiar with your cutting tools, you can start seeing better results and better profits.

Machine shops around the country are competing to take your business. So, what can you do to gain a competitive edge?
Your company’s profitability is directly related to its level of productivity and efficiency. While much of that is dependent on the efficacy of your employees and your processes, it’s important to remember that in the world of manufacturing, a worker is only as good as his or her tools. An idle machine becomes overhead when tooling components must be changed out due to early wear and tear or damage to the equipment itself.
Whether the tools of the trade include power tools, lathes or CNC machines, their effectiveness depends on proper usage and regular maintenance of cutting tools such as end mills, annular cutters and saw blades. If you’re experiencing premature tool failure, we have some tips on how you can save money by getting the most out of your tooling and machinery.
Related: The Guide to Choosing the Right Saw Blades for Optimum Productivity.
1. Maintain Your Tools and Equipment Regularly
Don’t wait until your tools require servicing to make repairs. Similarly, don’t rely on your advanced tooling to remind you to perform routine maintenance. Doing so leads to unnecessary downtime that can cost your company thousands, and oftentimes the servicing is performed too late. Instead, create a maintenance schedule that outlines change-out schedules, lubrication schedules or replacement timelines. Be sure to document these activities so that all employees, regardless of shift, know exactly where each tool or machine is on their maintenance schedule requirements. Additionally, these documents can identify recurrent machine failures or needs, helping you improve future machine and tooling reliability.
Check out these tips from industry leading cutting tools suppliers on getting more out of your cutting tools.
a. Stop band saw blade breakage
New band saw blades have razor sharp tooth tips. To withstand the cutting pressures used in band sawing and avoid microscopic damage, the tooth tip must be honed to a micro-fine radius. To avoid blade failure and get the most out of your new band saw blade, follow these blade break-in tips from Lenox Tools:
b. Use tool reconditioning services
For getting more life out of your standard and special Carbide and PCD tooling, Guhring has an entire Reconditioning Division committed to bringing your cutting tools back to factory quality, condition and performance. They offer reconditioning services for drills, step drills, carbide end mills and reamers on both Guhring tools and competitor tooling.
c. Take advantage of cutter remanufacturer programs
The Slugger Cutter Remanufacturing Program through FEIN allows annular cutters to be sharpened up to 6 times (excludes Carbide cutters). Getting reground on the same CNC machines they were manufactured on ensures they are just as true and just as sharp as the day they were made. They also offer recoating services at an additional cost.
If you’re interested in saving money and want information on programs like these, reach out to your local M&M Sales & Equipment rep or call 800-592-4516.
2. Get Organized
One of the fastest ways to damage or lose frequently used tools and tooling components is by failing to return them to their proper place when not in use. How often have you heard the complaint, “I can’t find the grinding wheels” or “Has anyone ordered new drill bits? I’m all out.”
Organizational problems like these are so common in industrial facilities that an entire lean management strategy has been developed to cut down on the time employees spend searching for items. 5S is a lean management process that increases productivity and transforms workplaces from one of disorder and clutter to one that is organized and efficient. The 5S methodology includes Sort, Set in Order, Shine, Standardize, and Sustain. Set in Order is one of the 5S’s designated for organization. Some methods of Set in Order are simple and straightforward like labeling bins, shadow boards and peg boards for power tools, cutting tools, and accessories like grinding wheels and drill bits.
Other methods require a more strategic approach, such as industrial vending machines. Whatever method you choose, you can greatly reduce lost production time due to lost, missing or damaged tools. Another advantage to better organization is that you can keep a closer eye on the replacement parts you need to repair or service your tools and equipment.
3. Train Employees Regularly
Every facility has its own unique roadmap to optimum production, one that is guided by the CNC machinery and tooling needed to do the job. Cycle time, metal removal rates and material costs are just a few of the considerations that vary from one shop to another. That’s why it’s critical to train both new hires and veteran workers on your machines and your policies. Pay attention to areas that employees are struggling with, as well as recurrent tooling issues. Then, devise specialized training on those procedures. By educating your staff on the processes specific to your shop, you can help them do their jobs safer and more efficiently, while cutting down on unnecessary wear and tear on your equipment.
4. Say Goodbye to Outdated Tools and Machinery
As difficult as it may feel, retiring old and inefficient tooling and equipment is essential to your productivity and profitability. Regularly assess the performance and reliability of your equipment and tooling. Old or obsolete equipment should be swapped out for advanced versions that are more accurate, faster and more reliable, ultimately providing faster payback on your investment.
Related: What’s Machine Downtime Really Costing You?
By following these tips, you can not only get more life out of your tooling and equipment, but also increase production. According to an article in American Machinist, businesses spend about 80% of their time reacting to maintenance issues instead of preventing them. Consistently monitoring tooling and equipment usage, as well as keeping regular maintenance schedules can reduce unplanned downtime and lead to longer tool life. Which, as we all know, means bigger profit and less wasteful spending.

We know that shutdowns are a real possibility. Inadequate preparation of pumps and sumps can lead to major catastrophes when left unchecked. Machine operators should be mindful of three factors that can have an impact on sump health: coolant concentration, pH and reserve alkalinity. But it doesn’t stop there. Take a look at these expert tips from Master Fluid Solutions on how to prepare your sump for a temporary shutdown for a quick and smooth re-opening.
Download Preparing your Sump for a Temporary Shutdown
Step 1: It’s critical that the systems be in as good shape as possible when they are shut down. Concentration, pH, reserve alkalinity and other factors should be in the specified range.
Step 2: Remove the tramp oil from the sump. Tramp oil is both food and shelter for bacteria, which is the main cause of the rancid smell that can come from the coolant.
Step 3: Clean out chips and sludge from the sump. Chips and sludge are also food and shelter for bacteria. A Sump Sucker will make this job quick and easy.
Step 4: Bump up the concentration. This adds a little more pH buffering to the sump, which helps to prevent bacteria. Our recommendation is to bump up the concentration to the maximum recommended operating range for the product being used. If adds are needed for alkalinity, pH, or other factors, add them a day or so before the system is shut down.
Step 5: Make arrangements for whatever sampling you want to be completed and communicate the results before the shutdown occurs.
Step 6: If possible, recirculate the coolant in the sump during the shutdown. In many cases, maintenance staff may be present. Have them turn on the coolant pumps to recirculate the volume of the sump several times over.
Step 7: If you are going to run a centrifuge over the shutdown, make sure you have sufficient tramp oil and waste capacity.
Step 8: Make sure you have an adequate supply of coolant as well as cleaners such as Master STAGES™ Whamex XT™ and Master STAGES™ Task2™ GF to help keep your systems running smoothly and to prevent any issues when you resume normal operation.

Everything these days seems to be moving at lightning speed, with many folks thinking the quicker the better. From procurement to delivery, we want it done, and we want it done yesterday. However, when it comes to machining applications, these speed and feed rates can make or break the reliability of your milling cutters and cause damage to your expensive machines. Some of the top things to consider in tough and demanding milling operations are heat, vibration, stability, functionality and adequate metal and chip removal rates, as well as good process security.
That’s why it’s critical that you understand the fundamentals of the cutting tools and equipment you use daily. Without the right milling cutters, cutter bodies and cutting tool technology, those high speeds can not only slow or stop your shop’s productivity, but also eat away at your profits.
Fortunately, our partnership with the industry’s most innovative manufacturer in tooling technology, Sandvik Coromant, has provided us with helpful advice and tips to help you get the most out of your machining operation. Need answers right now? Call us directly at 800-592-4516.
The Shank is the cylindrical shaped part of the tool that is used to hold and locate it in the tool holder. It can be round and held by friction or held in place with a set screw.
The Flute of a milling bit are the deep helical grooves running up the cutter.
The Tooth is the sharp blade along the edge of the flute that cuts the material. The flute, with the help of the rotation of the cutter itself, helps to expel the material up and away from the cutting surface.
The Helix Angle describes the flutes of a milling cutter. Usually flutes are helical to allow gradual entry into the workpiece. If flutes were straight, they would enter the workpiece at the same time, causing vibration and potential damage. Tighter helix angles with higher rake angles often provide a better finish.
The Milling Cutter Materials are often high-speed steel (HSS) or carbide. As a rule of thumb, softer materials can be machined with HSS and harder materials require carbide. But note that while HSS is less expensive than carbide, it does wear out faster, requiring more frequent changeouts.
Coatings are helpful in improving the hardness of a cutting edge and to reduce friction on materials that have low thermal conductivity, or are unable to control heat-build up on both the milling cutter and the work piece.
The Tool Life of your milling cutter is critical. If you have high production and heavy workloads, it’s critical to invest in the right tooling that can keep up with the volume of work. Choosing inexpensive or inadequate tooling costs time and money on wasted material, scrap, wasted tool spend and added wear and tear on your machines.
It’s not enough to just choose the right milling cutter for the job. You also need to understand how the milling cutter, the workpiece, and the machine all work together to get the best machining results.
The following is from Sandvik Coromant:
A. The Milling Cutter
Milling isn’t a one-size-fits-all operation. Milling cutters cover a wide range of traditional operations that remove metal from workpieces, but milling cutters can be also be used in alternative ways to produce holes, threads, cavities or pocketing. The features to be milled require careful consideration as milling cutters come in many shapes, sizes, coatings and cutting surfaces. Does the milling depth require extended tooling or does the feature to be milled contain interruptions or inclusions? These are common questions you should ask yourself.
B. The Workpiece
Consider the workpiece and its machinability. The size part to be milled is limited by the machine’s capabilities and depth of cut required. Additionally, the material’s characteristics will determine the overall functionality. Characteristics like hardness, thickness, rigidity, chemical resistance, heat treatability and thermal stability all play a critical role, so special attention must be paid to choosing dedicated tooling and milling strategies.
C. The Machine
The milling method you choose will impact the type of machine you need. Typically, there are two configurations, vertical milling machines and horizontal milling machines. There are multitasking machines (MTM) that can handle a variety of operations including milling and lathing, but there are limitations. Choosing the right machine for the job will save you money on equipment repair and replacement, as well as saving on scrap costs.

Any time you activate a cutting tool on metal, you generate heat. If that heat isn’t carefully controlled and begins to accumulate, the cutting surface can become deformed and damaged. Damaged workpieces then become expensive scrap.

CNC machine coolants are used to bring down the temperature at the point of contact. High pressure cooling like that offered by Dorian Tool’s Jet-Stream™ tooling is introduced at the exact point of contact to remove heat at high rates and pressures, eliminating the vapor barrier common with standard coolant systems. That barrier typically blocks standard low-pressure coolant, limits the amount of lubrication to the cutting edge and actually causes chips to fall back into the tool. That’s why standard coolant systems often result in damage to the workpiece or lead to an inferior finished product.

What is a KanBan Board? The term KanBan was introduced by Taiichi Ohno, the father of the Toyota Production Systems (TPS), in Japan as a lean manufacturing tool. In Japanese kanban literally translates to ‘signboard,’ used as a final call for orders from shopkeepers for orders in villages. Originally created as a simple way to control and manage workflow and inventory at any stage of production, KanBan uses cards or flags to signal when it is time to manufacture the next part, according to customer demand. The process helps to minimize waste, limit work-in-progress and reduce the amount of capital tied up in inventory.
Looking to speed up production and cut down on wasted time in your shop?
A KanBan board may be the solution you’ve been looking for. Kanban boards are agile tools used to help your workforce or organization visualize the flow of production, limit work-in-progress (WIP) and maximize efficiency. It can be one of the simplest and most effective ways to ensure your facility manufactures only what is needed for customer orders, rather than wasting time and supplies creating unnecessary goods. Create the right product at the right time at the right cost. When done right, a KanBan board can save you time and money. When done wrong, Kanban boards can add confusion and inefficiency to your operations.

Are you looking for ways to identify and stop bottlenecks and waste in your facility?
Sure. Who isn’t looking to optimize operations to achieve maximum results with minimal investment? For that reason, many manufacturing facilities and machine shops alike are starting to look to lean manufacturing techniques to help them get there.
Kanban systems are one such method that offer production teams the support they need to get the most out of their operational processes. Following the design of pull systems and just-in-time inventory plans, Kanban cards are small cards with important information related to specific operational processes. These cards can include information about materials and part descriptions, identifying bar codes, routing information, lead time, supplier information, order date, due date, responsible parties and more.
Kanban boards are ideal for controlling production and making operational processes visible when used as part of a lean manufacturing program. Kanbans are best described as visual markers that highlight each step of the manufacturing process. Kanbans not only helps to visualize the workflow process, but also the actual work that passes through the process. By increasing the visibility of the work to be done, over time you begin to eliminate wasted labor, inventory and time.
