The clamping method of parallel shank twist drill is basically the same as that of using drill chuck to install clamp center drill.

a) clamping
b) Insert directly into the taper hole of the tailstock sleeve
c) Transition cone sleeve

The taper shank twist drill can be connected with the machine tool directly or through the transition sleeve. When the taper number of the bit shank is the same as the taper number of the tailstock sleeve taper hole, the bit can be inserted directly to realize their connection. If their taper numbers are different, they must be connected to the tailstock of the lathe through a transition sleeve.

When the twist drill in the Morse transition cone sleeve is dismantled, the wedge iron can be inserted into the waist hole, and the bit can be dismantled by tapping the wedge iron.
