A woodworking friend of mine gave on one last year while I was building handrails on his deck. I’ve been hooked ever since. I build handicap ramp and have a lot of pickets to install and decking boards. We countersink each picket top and bottom and the outside of each decking board to prevent splitting. They are AWESOME. We were using a regular drill bit but many were broken. These will also break but not as fast as the drill bits. 2 very important things, no direction on how to open the container, hold bottom and pull top. Next, be careful closing container, make sure all bits are all the way down or if you push top of the lid down fast and a bit is not resting on bottom it will come through the top and OUCH. They are very sharp. That said, if you’ve never used this countersink you will love them. I just bought another set.

I really like these counter sinks. They drill quickly and clean. I use them on all of my wood projects from treated lumber decks to building furniture pieces for the family. They remain sharp and last for quite a while. On my last bit I built a 12 ft. x 12 ft. deck with steps, a 5 ft. x 8 ft. deck with steps (counter sinking all of the deck screws), a book case, a cabinet for my wife and a couple of tall outdoor Adirondack chairs before retiring the bit. This set with 5 bits should last a long time. One secret to getting them to last is drilling like a machine, straight in and straight out. I gave my dad (in his 80's) 2 counter sinks and they didn't make it to 10 drill holes. He would kind of go in straight and would start tilting his drill on the way out and they would snap. I gave him a couple more and he improved his drill skills. With reasonable care these will last. I'm Happy !

Had high hopes for this set, but the quality control wasn't there. Ended up being able to use only half of the bits, as 3 of the 6 were warped (bent) right out of the box. You can easily test this when you put them on your drill and spin them, and look at the point of the bit. On 3 of the bits the point was in a good fixed, tight place. The other 3, the point was making a very noticeable circle/swivel, which obviously means the bit isn't straight, so it won't counter-sink properly, and/or will damage your material. And anyone who knows bent bits, it's very difficult to hand bend them into perfect position. Overall, pretty disappointing, but I will give this manufacturer the benefit of the doubt I just got a bad batch, and I will try to order one more time.The bits that did work, were sharp, and strong.
