Title: Drill bits.
Review: Well, I purchased these as I needed them for some shelving I was putting up. I needed these to drill recessed spaces for my screws.Well, as I’m not inexperienced in using previous similar bits, I thought that they would work well. Sadly they didn’t. Initially it was ok, but they soon blunted and stopped cutting and I had to replace them with stronger bits from my local DIY store.Not really recommended. I give it 2 stars as it was well presented.

Review: I have always wanted countersink drill bits and recently had a project that required them. I love the fact that these take care of the countersinking as well as the pre-drilling. Great product.

Review: This set came very quickly and look and feel very high quality. Where they feel short is after using them on a piece of chrome moly steel they stopped working and completely dulled out after 3 holes. I am sure they will be fine for softer metals but do not get these for anything harder.

Review: These counter sink bit set are a good value for the money. You are getting a decent size selection here and the buts have held up fairly well for me so far. Only think I noticed is that the bigger bits seem to be slightly sharper than the smaller bits.

Review: I needed some countersink bits for a woodworking project i was doing and picked these up on a whim. It looked like what i needed and the price was right. Quality wise, i would say that these are ok, The bits feel a little brittle but as long as you dont drill into anything too hard or put any flex on them they should be ok. For the price – these are a decent option – not the best option.
