Most of my work is done with normal router bits. Which tend to be 1 or 2 flute straight bits. My experience is router bits don’t have the cutting length as milling bit. But I haven’t had them tear out bad even on plywood.

Cutting speed is defined as the rate at which the material is removed from the workpiece during machining. In simple terms cutting speed is the metal removal rate. The unit of cutting speed is meters per minute (m/min).

The tip of a milling bit helps determine its purpose. Fishtail bits produce a flat surface at the bottom of your cut. Ballnose bits create a rounded bottom of your cut. These bits are ideal for 3D contouring or stepped layers, as the rounded tip reduces ridged edges in consecutive passes.

Note: This collet is not compatible with the standard DeWalt collet nut, it requires a Precision Collet Nut. This precision grade collet is great for making the most accurate cuts. The low runout potentially improves cut quality, tool life, and...

Certain materials require you to remove material faster than others. For instance, a soft plastic like HDPE will melt if the chips are not expelled from the bit quickly enough. You will want to use a single or 2-flute end mill for a material this soft. For harder materials less prone to melting, you can use more flutes: just be careful with your cut depth, so you don’t break the bit by trying to carve too deeply into a hard material.

Cutting speed = πD for one complete rotation. Similarly for two rotations it is going to be 2πD and so on. Therefore for “n” number of rotations Cutting Speed can be denoted as πDN. Where π is a constant, D stands for Diameter of the part / Tool, N stands for number of revolutions in rpm.

Compression bits have a primarily “neutral” cutting action and smooths both the top and bottom edge of the cut pass. This is achieved by the lower part of the bit utilizing the up-cut style, and the upper part of the bit utilizing the down-cut style. As a result, these bits are recommended primarily for thicker materials which will be cut through entirely. If your project requires shallow cuts, it may not be the best choice because only the bottom (up-cut) portion of the bit will be used, and the top (down-cut) portion of the bit will not be used to finish the smoothing.

We also sell a variety of bits designed for specific applications. V bits, or V-Carve bits, create a pass shaped like a “V” and are commonly use for detailed engraving or signs. We also sell bits designed for fine-details, engraving, or working with PCB.

Face Milling cutter

Up-Cut, Down-Cut, and Compression The cutting style of a milling bit identifies which way the material chips are removed from your project, in addition to which side of the cut surface is smoothed.

Up-cut bits expel the cut material upward and smooths the bottom of the cut pass. It pulls heat away from the bit, and is a good choice for plastics, metals, or other materials that are prone to melting or burning. However, because of the bit’s design and upward-pulling motion, it can fight the clamping system you use with your material, especially if your material is thin.

Generally speaking, more flutes on an end mill means a smoother edge finish. More flutes also means there is a smaller surface area to eject cut chips away from your stock material. This means you will need to use a slower feed rate, so the bit has time to properly dispose of the cut materials. By using fewer flutes, you can remove material quicker but will have rougher edges on your cuts.

Down-cut bits push the chips downward (towards the material). This cutting style is prone to melting or burning your material, especially if your job requires many passes. The benefit to this style of bit is that, by pressing down against the material, it can help thin materials remain secured to your cutting surface. Additionally, the top edges of your cuts will be smoother than if you use an up-cut bit.

These methods include annealing, stress relieving, stress equalizing, solution treating and age hardening.
