GREAT PRICE, GREAT DRILL BIT SET
Great price for a Cobalt bit set, used these to extract a broken bolt on a motor block and also to drain out oil on old compressors so i could recycle them. Easily cuts through metal without struggling.Why buy one drill bit at Home Depot when you could have a whole useful set? 5 stars

The Right Tool for the Right Job
I was attempting to drill out some pretty stubborn screws on a derby cover on my Harley. The previous owner proceeded to strip out all five of the screws. I tried all the tricks to get them out including a rubber band, an easy out, etc. with no success. The metal was just too soft. This is why I replace these types of fasteners with new stainless steel.I purchased these drill bits because I was a sheet metal mechanic in the Air Force and I know that cobalt drill bits are what you need for harder types of metals. The heads on the screws were soft but the shank was not. After loading up my first cobalt bit and applying heavy pressure and slow speed, the bit ate right through the center of each screw. I went up two more sizes and ream out the hole. One more size jump and the head of each fastener popped off onto the drill bit just as I expected.

Not up to expectations
Product came in a nice case, looked good, but could not drill through metal as advertised.

Strong enough to drill steel
Rebuilding trailer I must have used metal much harder than original body and these bits did the job. Must have gone through 8 drill bits before I gave up and ordered these. Bottom line these drill bits able to cut through steel that had dulled my previous bits.

The bits are are made out of cheap coat hanger steel.
Bought this set of bits to bore a 1/2” hole through a 1/4” thick steel square tube. Punched the spot to get started, applied a liberal amount of tool oil to the 1/32” and got about 0.001” deep when it snapped. I then proceeded to snap every bit up to 1/8” trying to start a pilot hole and gave up on these bits.

Very good, especially for the price.
I've used this in up to 1/4" steel and they work great. Was worried about quality due to the low price. I'd like a set of these up to about 9/16"
