Split-ring stop collars clamp around drill bits and hold securely in place. When tightened, they clamp over the complete diameter of the drill bit shaft without marring.
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.

These collars are very stiff. Very hard to tighten down. I thought I was going to snap the allen wrench trying to squeeze these down. Once set up though, they work fine. Hopefully once they are wore in a little they will tighten down easier.

Very hard to tighten down, snapped the first set screw 15 minutes out of the package.

The collars don't work all that well. Each collar is very hard and stiff. You could not squeeze them closed with a pair of vice grips. So do not think you will tighten them down a size with that allen wrench. Each collar will basically only fit a single size of drill bit. You could almost call this a drill bit conversion kit. Once you get them on, they work well. They are simply not as flexible as you would think.
