This 150 millimetre magnetic bit holder allows any 1/4 inch hex shank bit to be used with a CENTROTEC chuck or a 3-jaw chuck with 1/4 inch or greater capacity. Theextra length makes it easier to access tight areas and increases your reach. The precision-milled hex shank eliminates wobble and run out for easy fastening.

The CENTROTEC shank is compatible with the quick-change CENTROTEC chuck system and 3-jaw chucks. When used with the CENTROTEC chuck, the hex shank seats directly into the drill spindle for maximum power and control.
