A stainless steel drill chuck that replaces the hand-tightened chuck on Three-One Motor mixers, for shafts that need a chuck handle to clamp securely. Holds shafts of ø8 mm and below.
Replaces the hand-tightened chuck: fits in its place on the motor's drive shaft
Keyed clamping: the chuck handle tightens harder than hand pressure for heavy or long shafts
ø8 mm and below: the same shaft range as the hand chuck
