20mm Carbide End Mill

What is an end mill?

It is defined as a shank type milling cutter that has a cutting edge on the outer surface and cross-section. An end mill is a tool that rotates and shaves the sides and top surface of a processed item with an outer blade and a bottom blade of a cross-section, respectively. End mills are especially used in precision processing of electrical, electronic and automotive parts and molds.

Selection of end mill

The performance of an end mill varies depending on the settings such as the number of blades, twist angle, inclination angle, relief angle and coating type, and a suitable shape is required for high-speed cutting operations.

Vibration occurred during cutting	Excessive primary outer relief angle Excessive protrusion of tool Improper cutting conditions	Reduce primary outer relief angle Reduce the amount of protrusion Adjust cutting and transfer speeds
Reduced cutting performance	Use unsuitable end mill Low outer inclination angle Rapid wear of cutting blades	Use an end mill suitable for items to be cut Increase outer inclination angle Perform early regrind
Sudden occurrence of wear	Excessive cutting speed Unsuitable outer inclination angle Upward cutting operation	Reduce cutting speed, modify outer inclination angle Consider downward cutting operation
