Set includes collars for 1/8", 3/16", 1/4", 5/16", 3/8", 7/16" and 1/2" size bits. 1/8" hex key also available (two per pack).
Select the proper collar diameter, slide it onto the drill bit, and tighten the single 1/8" hex screw. The split ring design tightens fully around the drill bit securing it in place. No damage to the drill's side edges or flutes will occur!
Stop Collars allow you to set precise cutting depths on any countersink or drill bit with a corresponding diameter.
