What is the difference between end mills and keyway mills?


Date:

23/06/25

1、 Different characteristics 1. End milling cutter: There are cutting cutters on both the cylindrical surface and end face of the end milling cutter, which can be cut simultaneously or separately 2. Keyway milling cutter: It is a type of milling tool with two types of limit error of blade diameter: e8 and d8. Keyway milling cutter has small spiral angle (20 degrees), groove depth, approximate straight line back folding, and is somewhat similar to Fried Dough Twists drill. 2、 Different uses 1. End milling cutter: mainly used for flat milling, groove milling, step surface milling, and profile milling. 2. Keyway milling cutter: mainly used for machining keyways and grooves, keyway milling cutters are very useful for milling keyways. For example, a 6MM end milling cutter is more prone to breakage compared to a keyway milling cutter when milling grooves, while a keyway milling cutter can cut through it in one go. 3、 Different performance 1. End milling cutter: End milling cutter can process flat surfaces. 2. Keyway milling cutter: Keyway milling cutters cannot process flat surfaces, and the cutting amount of keyway milling cutters is larger than that of end mills.
