Description
The straight shank is the most usual style on modern drill bits. The whole of the drill bit, shaft and shank, is usually of the same diameter. They are easy to centerless, grind or turn on a lathe. It can be held in a standard drill chuck, which must be tightened-only friction prevents slipping. Also can be held in a collet chuck (which must be tightened), practically for smaller sizes. Useful for very accurate centering.
