I'm a long time Kreg pocket hole jig user.I have had 3 different generations of the Kregs and if you're a Kreg user then you will know their drill bits come with stop collars.I've always wanted different sized stop collars for my other sized bits for various projects.I now have them.With so many collar sizes I now never have to worry about needing a collarHighly recommended

Packagine was minimal, but no damage. Each collar has two set screws to lock onto the drill bit. Some of those came out of the collars during shipping. As a result I am missing one of them.However for large drill bits you should only use one set screw anyway. That's because if you use two, the collar does not contact the drill bit but rather sits on the points of the two set screw, and it is impossible to get the collar to sit straight. So your depth of cut becomes is not accurate.I recommend on any drill from about 3/8" up, remove or back off one of the set screws and use only the other one to tighten onto the drill. That way the inner surface of the collar clamps up against the drill, forcing the collar to sit straight.I strongly recommend you do a test drill once you have the collar in place.Always tighten the set screw on the outer edge of the drill, never down in the flute as that will damage the drill.Good product, way better than the split ring style.These will fit any drill, imperial or metric.

Fits the bits better than some I've used. I use them for depth on carvings.
