Item TAC451301.1 13mm Keyed Chuck with SDS Adaptor from Total

13mm (½”) keyed chuck with SDS arbor designed to enable use of regular drill bits with SDS (Slotted Drive Shaft) drills.

SDS drills have a special chuck design for use with SDS bits that have indentations along their shaft for extra force and torque. Because of this, standard drill bits will not work with SDS drills.

Attaching this chuck adapter enables using standard drill bits with your more powerful SDS drill.

To use, simply thread the SDS arbor onto the bottom of the chuck.

Then securely tighten the special left-hand threaded screw from the top of the chuck, in a counter-clockwise direction.

You can then attach the SDS bit adapter onto your SDS drill chuck, and use the standard keyed chuck for standard drill bits.
