When choosing a milling tool, the number of teeth on the tool is an important consideration. A dense-tooth milling tool can have 8 teeth with a diameter of 100mm, while a coarse-tooth tool with the same diameter has only 6 teeth. Coarse metal milling tools are ideal for rough machining due to their large chip flute, which reduces friction between the workpiece, cutter body, and the chip itself.

Also, when milling holes, the size of the tool also requires great attention because if the milling cutter diameter is too large or too small compared to the hole, it could cause damage to the workpiece or tool.

When selecting the right milling cutter, the major factors to consider are cutting power and workpiece processing size. For instance, when selecting the diameter of a face mill cutting tool, the power requirement of the tool should be within the power range of the milling machine cutting tool.
