Overview
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.

After reading the reviews I opened my new set of split collars to if if what ither reviews were saying were true. The only collar that there was a problem was the 18", to start off the set screw did not tighten down so by using visegrips and working the screw in and out it finely closed down on the bit and held with no problem, had to use a screw driver to open to take it off, but worked flawlessly after that. I can recommend to others.

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.

These seem fine IF the bit you want to fit is one of the sizes supplied and IF the collar was machined to spec. Unfortunately for me, the one collar I needed the smallest is NOT machined to spec and doesn't have enough give to be usable. None of the collars give AT ALL. In short, for me this set was a waste of money.
