Guidelines for correct usage of carbide drills ᭹ Holders for solid carbide drills: A collet chuck holder is recommended for use with carbide drills. When using a milling chuck holder, a collet chuck with a straight shank or straight collet should be used. Collet chuck ᭹ Chucking drills: Radial run out and lip height should be less than 0.02mm. If run out or lip height is larger (close to 0.05mm), machining is possible. However, less accurate holes or short tool life may be a result. Overhang length should be as short as possible. ᭹ Coolant Supply: When using a drill without a coolant hole,...

Regrinding Please refer to the following instructions prior to regrinding DSW type drills. Before regrinding ᭹ Check the damage on cutting edge ᭹ If large fractures appear on the edges or feed marks are found on margins, please remove these completely. Relief angle 1.
