So far, this has been the best counter sink drill bet set I 've used. I've done woodworking for years and have used many different countersink sets. These cutters cut super clean and fast with no slip so far. Wish I had been using this from the beginning. Very happy with this item. This item is a Definite must have for wood working.

Building an ipe deck with many 100's of countersunk fasteners, I hoped these would perform much better than the typical woodworker's special countersink bitts with the tapered drills I used for furniture, and they did, with one caveat. One of the bits clogged and countersunk poorly, looking under a microscope it was clear the grinding had completely missed one wing of the countersink cutters- it was flat and dull, with no cutting edge at all. A minute with a Dremel and a diamond grinding wheel and it was working great.Cutting so many holes in very hard wood these carbide cutters performed very well and saved a lot of time. Quality control could be improved, but an excellent value for the money.

The countersink was good. But 3 of the 5 pilot bits were broke in half at the set screw.

The countersink cut into oak very easily. Very satisfied.

I like these bits, they work well, but I am disappointed that there is no marking on the drill bit itself of the size. It is hard to tell them apart, especially the smaller ones. I'd like to recommend that they stamp into the bit itself the size. If I knew that they did not have a size on the bit, I probably would have kept searching for another product that had the size stamped into the bit itself. Other than that they work well.

Absolutely garbage. Drill holders break after 2-3 uses. Never buy again.

Great set of drill and countersinking set. They are described as screw size, not millimetres. My bad. Easy to use. Well made and great finish. Easy to adjust and use.
