Flutes are the cutting edges on a bit. Fluted bits get their names based on the number of flutes present on the bottom of the bit (for instance, our 2-flute bits all have two cutting edges).

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.

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.

Small diameter internal threads can be cut by hand, using a tap holder / wrench. The tap is manufactured from high speed steel. Cheaper versions are manufactured from carbon steel. In both cases they are hardened, in order to withstand the thread cutting they will endure, throughout their usable life time.

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.

The purpose of the ‘tap’, is to cut a thread into a ‘hole’, that has been accurately drilled to a specific size. For example, a 5mm hole can be ‘tapped’ for a M6 (metric) thread. A 6.8mm diameter hole can be ‘tapped’ for a M8 screw thread. This varies and depends on whether a coarse of fine thread is required.

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.

Oct 9, 2021 — The majority of woodworkers and carpenters rely on a hands-on approach for calculating angles, typically referring to them as miter angles.

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.

Taps are normally bought as a set of three (see below). The ‘taper’ tap is the most used, as it will cut a thread through a hole. If a thread is required in a ‘blind’ hole (a hole NOT drilled all the way through), the taper tap is used first, followed by the ‘intermediate’ tap and finally the ‘plug’ tap. Using all three taps on a blind hole, ensures the thread is cut almost to the bottom of the hole.

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.

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.

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.
