About Collet Accessories
Collet chucks are a type of subchuck tool holder that hold, or collar, round shanked drill bits for milling cutters. Collet accessories include collet wrenches, collet key adapters, collet clamping nuts, tension springs, coolant rings and other items that customize, enhance, or better enable a collet chuck to perform. Items vary by size, taper, projection and other dimensions. If using a collet to ream a hole, another option might be to use a hand reamer.
