The difference between two-flute milling cutter and three-flute milling cutter-precision requirements are different:

1. The size of the keyway milled by the two-edge milling cutter can reach high precision, and the end face of the keyway milling cutter has no center hole, and it can be directly fed downwards, instead of the ordinary three-edge milling cutter due to the center. The center hole can not be directly fed downwards.

2. The keyway milling of the end mill of the three-flute milling cutter can’t reach the precision of the keyway milling cutter. When these two types of milling cutters are milling, there is no difference in the three elements of milling.

3. Milling cutter is a rotary cutter with one or more teeth used for milling. When working, each cutter tooth intermittently cuts off the margin of the workpiece. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines.
