I've been using these for a year now and have had no issues. Much better than the set screw type. Just use to correct size drill bit and they work perfect. The collars are clearly marked. ### ⭐⭐⭐⭐⭐ Works great *by R***S on January 31, 2026* Very useful ### ⭐⭐⭐⭐ Very simple tool but well made and useful. Watch out for slipping! *by J***R on November 26, 2023* They’re pretty simple, just a piece of metal with a few holes, but they do the job pretty well. These drill stops went on my bits easily and didn’t damage them at all, though with coated bits you will need to really tighten the stops on to prevent slipping. I found that if I didn’t double check the stop depth regularly and hadn’t really tightened them enough, they would scoot up the bit without me noticing. It can be difficult to tell how tight is too tight, as I don’t want to damage my bits, but so far no issues with that. Overall I’m quite happy with them, a good value for the price. ## Frequently Bought Together - POWERTEC Drill Bit Stop Collar Kit with Imperial System Size Markings - 7 Piece Set Adjustable Depth Stop with Allen Wrench - 1/8", 3/16", 1/4", 5/16", 3/8", 7/16", 1/2” (71491) - Milescraft 1334 Joint Master – Self-Clamping Aluminum Doweling Jig.
