wolfcraft Universal Depth Stop Set, 3 Pcs. I 2755000 I For restricted-depth drilling

Works well as a drill depth stop. Unlike some of the cheaper stops, the tightening screw doesnt actually touch the drill bit but clamps the 2 pieces of the depth stop together. A much better idea.

Proper depth stops which hold very tightly onto a drill bit which makes accuracy in workmanship. They are also made out of high quality metal which assures durability. I highly recommend

The depth stops clamp round the drill, so they can be attached to the drill in any position with almost no risk of damaging any cutting edge on the drill. The fit of the 6mm /1/4" depth stop to a 1/4" drill is marginal, since the locking screw has to be undone almost completely to allow the depth stop to be fitted to the drill. However, the supplied screw is just long enough rather than just too short, so the depth stop still does its job. Other than this, the depth stops fit very well on to the correct size of metric or imperial drills.

Good quality. Gave accurate drilling depth , quickly and v good value , v easy to use

With lots of other depth stops there is a single grub screw trying to grip a round drill bit. What happens with that is that it slips while you're drilling and you end up missing the stop. Very frustrating, especially if it's the difference between a good job and ruining a perfectly good bit of wood.With these depth stops there is a hinge on one side and a nut and bolt on the other, forming a much tighter grip around the drill bit, over a greater surface area.The result is this depth stop doesn't budge.Yes it costs significantly more than most others on ebay, but it is very good and I'd highly recommend it.

Some of the cheaper depth stops use two small grub screws to secure the stop. and these are fiddly to set up, and can slip. The wolfcraft uses a hex head screw on a fixed nut, and expands or contracts the aperture which is on a hinge. So it grips the drill bit securely and easily. It does not slip. I had bought a set of the cheaper two grub screw type depth stops, but I never use them now. The set I bought had 3 sizes. 6, 8, and 10 mm, which fits my needs for dowel use. Bit expensive, but I think they are worth it.

They work but they will mark whatever you are drilling into if you don't stop pushing on the drill before the stop meets the material you are drilling into. You could solve this by using masking tape on the drilled material but that creates its own issues... So I've gone back to using tape on the drill bit to set depth... Also they could do with offering a stop another size down too.

Easy to fix to drill bit with the complementary Allen key. Have used the smaller size with a 5mm drill bit. Found it gave me a dredged of accuracy guiding the drill bit into the located spot. The dowels fit perfectly. It does mark the wood so be prepared for some fine sanding to finish the surface of your project.
