ニック付きエンドミルとは　中加工荒用エンドミル　タフニックエンドミル | オーエスジー

An end mill with a nick is an end mill with a nick in the middle of the blade of a square end mill that is designed to make chips finer and at the same time reduce cutting force. Compared to square end mills, end mills with nicks can process many cutting depths at once. The machined surface is better than the luffing end mill, but rougher than the square end mill, so it is also called an end mill for semi-roughing .
