Incredible when used properly
Make sure you countersink BEFORE you drill your hole, especially in wood. This goes for all countersinks.
If you countersink first, you'll get a gorgeous, smooth countersink hole. If you drill the hole and then countersink, you'll get an ugly hex/square/octagonal wobble pattern. You can somewhat fix this by spinning the countersink backward.
This is a great set. Having 3 bits means they'll last a long time. The cutting angle is the same.
Countersink BEFORE drilling the hole!

Countersunk
Good set of countersink bits to have in the just the right sizing in my opinion. Cuts have been smooth and easy. I've got these mounted by my drill press and they'll get used quite a bit. I do wish they came with a small carry pouch or case. I know that's picky, but I'd like to get a second set for my tool bag. I know it keeps costs down but that'd just be icing on the cake. Overall, great set.

Good, Accurate, Sharp
These are pretty well made. The size of the bit is the actual size marked on the tool. These are labeled General Tool NY New York but the are made in china.
Good up to 2000 rpm.
Wood, Plastic, and Metal.
1/4" shank. Drill only, no quick chuck.
5 blades. Many have 4 causing more vibration and jumping.
These are probably best used in a drill press.

A LOT OF USE OUT OF THESE
THIS SET MAKES MY COLLECTION OF COUNTERSINKS COMPLETE, I HAVE ALL THE SMALLER DIAMETERS ALREADY. I FOUND A LITTLE CHATTER IN COUNTER SINKING WOOD JUST LIKE MY OLD COUNTER SINKS DO. HOWEVER I FOUND NO CHATTER WHILE USING IT ON METAL. IT’S EASY TO SEE THAT THESE COUNTERSINKS ARE MADE OF A HIGH SPEED STEEL, WHICH MEANS I WILL BE GETTING A LOT OF USE OUT OF THESE.

Received correct material in a timely manner. Appeared to be of good quality. So far only used the larger countersink in aluminum.
