## Customer Reviews

### ⭐⭐⭐⭐⭐ As described
*by A***D on February 5, 2025*

I tried theses as soon as they arrived and have to say I am extremely satisfied. I have used the standard ones and have had nothing but grief . So far these have eliminated every issue . They lock on securely , stay in place and did not mar the bit. I used my Dewalt XR 20 volt drill too! Highly recommend.

### ⭐⭐⭐⭐⭐ Squeezes the entire bit rather than screwing into it.
*by M***E on April 23, 2025*

Best set of drill stops I've seen or used. Well machined and engraved with the size. I started with the set from Harbor Freight which were slightly cheaper than this, however they used the single set screw design which tends to rotate and fall off during use. This design squeezes then entire bit with the collar- a far superior design. Also, this design doesn't allow the allen screw to mar and damage the drill bit like the other design does. I can't see how this could be any better.

### ⭐⭐⭐⭐ 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.
