How to use
Secure the cylindrical shank of the KWB COBALT HSS CO drill bit in a compatible chuck. Select an appropriate cutting speed and feed for the material being drilled; slower speeds and steady feed are recommended for stainless and alloyed steels to reduce heat buildup. Use suitable cutting fluid for metal drilling when necessary to improve cooling and chip evacuation. Drill with firm, consistent pressure and withdraw periodically if deep holes are required to clear chips.
Usage recommendations
For best results when drilling stainless and high-alloy steels, use lower cutting speeds, adequate cutting fluid, and moderate feed rates to extend tool life and maintain hole quality. Inspect the bit before use and replace when wear or chipping affects performance.
