Brace Accessory 1/4 inch (6.35 mm) hex internal Bit Holder with Screw and conical square Shaft

Suitable for hex shank drill bits for which a 9.5 mm deep receptacle is too small. In this adapter, the drill bits sit securely and are fixed with the supplied screw. Our Japanese auger bits with a hex shank and drill diameter up to 19 mm thus become an ideal tool for hand braces.
