Best Counter sinking bits I have hadI didn't realize how much I would appreciate being able to countersink screws until I got this set. It makes everything look more professional and I use it often.If you're like me, and have a habit of working on several projects at once, it's very nice to have a bunch of countersinks so you aren't rushing from place to place trying to find the *one* that you have somewhere. At the price, i highly recommend.I got theses counter sink bits for my woodworking projects I am building some cabinets doors and frame for my sisters kitchen and they have been a great tools to have in my shop they come as described in the description of productAnd I Highly recommend themIf you do any serious woodworking then you need a good countersink set. This one is pretty good. A decent variety of sizes. I tested them out and, well, they do the job. Plain old steel bits, nothing fancy. They each come in their own individual plastic capsule with an allen wrench inside which is thoughtful and should prevent rusting. Not much more to say about these. If you need a set this is a decent one and the price is fine.These are nice countersink drill bits that come in a good variety of sizes. I'll be honest, for years, I have simply drilled the main hole with a smaller bit and they used a larger bit to drill a shallow countersink hole when I needed one. It worked ok, but it's definitely not the most professional way to do things and it leaves open the chance for a screw up. I'm glad that I now have these bits on hand so that I can just simply drill legit countersink holes when I need them.
