For harder material you need stronger cutting tools with more flutes and smooth (yet not so deep) cuts. If you want to cut deep in materials such as plastics or aluminum then you want fewer of these cutting teeth. Everything above five flutes indicates finisher end mills used for very fine finishes. End Mills can have only one or two but also up to 12 flutes, however two to four flutes are most common. How many Flutes for which applicatons?įlutes are the spiral-shaped cutting edges at one end of the cutter. We are sure that you would like to avoid that. Using the wrong milling cutter will also pretty quickly result in broken tools. Sure, technically you can try to cut any material with the same end mill, but the cutting performance and the finish quality on the workpiece will vary from excellent to inacceptable. For non-ferrous materials such as aluminum you will need different tooling shapes, materials and dimensions than for steel for example. This will narrow down the number of ‘potential candidates’ significantly as certain types of end mills are specifically made for certain metals/materials. So let us take a closer look at the most important aspects that you need to take into consideration.įirst ask yourself what materials you will want to cut with your new end mills set. Once you have answered these and other questions you will have a better understanding of what type of end mill is needed for your applications. How important are feed, speed and cutting performance?.How detailed are the features that you want to achieve in your workpiece?.What kind of material are you going to cut?.We recommend that you ask yourself a few important questions before making a decision: But, no matter which brand/supplier you choose to buy your end mills from, the truth is that there is no one-fits-them-all solution There are a plethora of distributors and manufacturers offering their milling cutters online, such as Harvey, Niagara, Janpro, Avvupro, Guhring, Mcmaster-Carr, and others. Carbide end mills are often used for finishing purposes.Ħ. This not only boosts your productivity but also allows you to cut a wider range of (harder) materials. Here is what you get for paying for the more expensive solid carbide end mills: higher rigidity, great heat resistance and substantially faster cutting speeds compared to HSS. The overall tool life is shorter though and you get more restrictions in terms of speed and performance. HSS are the go-to cutter for most standard operations. You also can expect to use them for a long time before re-sharpening as they have a good wear resistance. They are suitable for a wide range of materials including a lot of metals and of course weed. Just make sure you select the correct-sized collet for your device.High Speed Steel End Mills are less expensive than carbide mills. Wide Compatibility: Genmitsu TB04A tapered ball nose end mills are compatible with most desktop CNC machines, such as the Genmitsu 3018 Series, as well as other industrial CNC machines. Versatile: Perfect for 3D machining jobs like molds, rapid prototyping, models and other other precision parts processing, these Tapered ball nose bits can do the best.Īpplicable Materials: These nano blue coating bits have an HRC rating of 65 and are optimal for milling a wide range of materials, including plastics, aluminum, circuit board, wood, etc. This provides longevity and produces cutting results of the highest quality.Ĭost-Effective: Coming with 4x 2-Flute tapered ball nose end mills, Shank Diameter: 3.175mm, Radius: 0.25, 0.5, 0.75, 1.0mm, Cutting Length: 15mm, Overall Length: 40mm.
