Doozer: Used to countersink screws in a 1/4" sheet of aluminum. Cut quickly & does not seem dulled. Comes in a nice little case.

Tom Brown: Exactly what the doctor ordered

Lee Nelson: For wood and fiberglass they work good .
I bought them for work and use them multiple times a week and I have been very satisfied with them.
Like any precision tool use light pressure do not force it.

poetic_justice_: I really like these Neiko countersink bits, but cannot give them 5-stars. I've only used them with wood (pine and fir), not metal. As other Amazon members have pointed out, they arrive dull. As a result, every wood application I've used them on has been left with small burrs and uneven surfaces in the countersink holes. However, the wood screws I use cover 90% of the wood burrs and hide the uneven countersink holes. The remaining 10% of problems visible around the screw head I can usually sand out. Since I am not a professional carpenter, these Neiko bits are excellent for personal woodworking projects. Even though they arrived dull, they haven't gotten worse with repeated use, meaning the metal is higher quality than some of my drill bits. With a bench grinder and the right angle, I believe it would be possible to sharpen these countersink bits to a 5-star sharpness. I am no expert on metal, but I believe that once sharpened, these Neiko countersink bits could maintain their sharpness for some time. They would definitely make smoother countersinks with fewer burrs. Unfortunately, I don't have an angle grinder. However, even at 50% sharpness, these bits make decent countersinks...

Ron H: they are well made and come in a nice box...3 flats on the shank insure positive grip in the chuck...that extra bit of manufacture tells you they are superior in build.

Harls: Pretty good. Nothing to write home about, but they’re pretty good for the price. I use them on aluminum and so far so good. I’d say they’re on par with Irwin

ExAlaskan: Purchased the Neiko 10218A Countersink Drill Bit Set, M2 High Speed Steel, 1/4” Tri-Flat Shank | 1/4”-3/4”, 5 Piece Set with Carrying Case for general DIY use. The set arrived in an aluminum storage case. Even though the case is designed to hold the bits in a rubber-type padded insert, one of the bits came loose during shipping and it bounced around enough to dent the corner of the case. The case is still usable and there is no apparent damage to the bit.

PROS
• The 3-side bit shanks fit well and lock securely in all of our drill chucks.
• Bits appear sharp but have not tested them on various materials. Little doubt they will work well in wood and soft aluminum….real test will be mild steel.
• Good selection of sizes.

CONS
• Chucked each countersink bit in our commercial quality drill press (that has very little spindle runout) to check the wobble (runout) at the point of each bit. Two of the bits had very noticeable wobble. There is some question if we will be able to get a good quality countersink with those two bits.
• Clasp on case is already loose so we don’t expect the case to last long. At least the hinges are holding...
