These are the best Countersinks I've bought to date. Will buy again
Reviewed in the United States on July 23, 2026 by Harold

I am a novice at woodworking. I bought the 7-bit set to drill countersink holes to install metal inserts on a walnut desktop. Before I drilled on my project for real, I tested the 8mm and 10mm bits on unfinished soft wood boards. I got the best result with the drill set to "mode 2" (higher max speed), torque set at the "drill" position, and used a piece of blue tape on the drill area to reduce split. I had no trouble centering the bit. The hole and countersink came out very clean with the blue tape method. For my hardwood desk project, I used these same bits and drill settings. I did not use the blue tape because the desk surface is finished and unlikely to split. Centering was very easy and the countersink holes came out very clean. I felt that drilling the hardwood was much cleaner and easier than drilling the soft wood. Overall, I am very happy with the 7-bit set. For someone like me who will use them infrequently, the value is unbeatable.

This set will definitely get the job done. I am very happy with my purchase. It is not the nicest set and I'm not sure how well they would hold up against prolonged hardwood use but for now they have worked great without breaking the bank.

I got these for a basement bar remodel project with the intent that all I wanted was to get through this one project. They were more than adequate for that. However, the countersink cutter keeps coming loose from the drill bit and needs to be secured in place before getting a good countersink. They're inexpensive but the bits and cutters are sharp. Will they tackle a big project? Remains to be seen but I've been using them are other projects and they're still going strong.

They work like they are supposed to. I just wish that the countersink part was sharper. I have to push pretty hard to get it to work. Even have to push on cedar fence pickets, which are soft. On harder woods it takes too much effort. I would not buy these again.

Two operations in one, drill and countersink. The length adjustment is easy but not always ideal, but with a drill press doing 10-12 holes at a time, this is a time saver. I used to just mash down my bugle head screws until they were flush with the surface but that was not always possible and it looked inelegant. I still use a freestanding countersink bit for some things, but these are appropriate most of the time. Quality is good, sharpness is good so far.

This countersink drill bits are very functional and fit well on the drill. Also, the bits are very sharp and m durable. I’ve been using some of them several times and they still sharp and very functional. Good value for your money in these countersink drill bits.

I am new to woodworking and I didn’t really want to spend too much money until I could decide if it was a hobby for me. I purchased these and they worked great for the first couple of projects. Once I started to change the depths of the countersink it seemed that I could not get them tight enough to not spin on the drill bit. They may not have been meant to be moved, but then why send the Allen wrench to do so? In short they worked good until they needed to be adjusted.
