FAQ, Videos and more

Twist drills made of HSS (High Speed Steel) are mainly used for drilling materials that are hard to work, e.g. metals. There are two different types of twist drills for metal: With bit shank or with cylindrical shank.

This difference does not affect the performance, it ionly depends on the chuck. Metal drills with a bit shank can also be used directly in the drill. Simple HSS drills reach their limits with hardened steel. In this case, twist drills made of an alloy containing cobalt should be used, such as those offered by the manufacturer Keil. They can also be used to machine stainless steel and similar metal alloys.
