Please note, if you are buying for an older Foredom Bench Lathe/Polishing Motor - this model will only fit current BL Lathes models (ones built in 2002 and later with 7.9mm (5/16") motor shafts).
The Collet Holder comes with three different sized collets for holding accessories;
6.35mm (1/4")
3.18mm (1/8")
2.35mm (3/32") shanks.
You can use any accessory with one of these sizes. It opens up a whole world of opportunities to use attachments you normally use on your flexshaft or Dremel for instance. Ideal for woodworkers, jewellers, and other artists needing a multi option tool.
The kit includes an allen key, pin, and wrench for mounting different sized shank mandrels, sanding drums, bristle brushes, and other accessories.
