Cobalt Pro Drill Bit Set (6 Piece) is rated 4.2 out of 5 by 32.
Rated 5 out of 5 by from Only drill bit you need for 304SS I saw other reviews about this Cobalt drill bit as I was just blunting my standard HSS bits on 3mm thick Stainless Steel. These bits at a slowish speed a firm pressure and crucially cooled by a small amount of water completed 20 holes all with the 5mm bit with no indication of reduction in performance. Highly recommended.

Rated 4 out of 5 by from Worked well for stainless steel job. First time user of cobalt drills for a stainless steel job. Worked well - advise slow drill speed as more brittle than standard HSS products commonly used for general non stainless work.

Rated 2 out of 5 by from Slow and steady is the way I had 2 of these snap first try. The only way they work in steel is slow and steady but if they catch they will snap.

Rated 5 out of 5 by from Very sharp set of drill bits. Needed these in a hurry and my local Toolstation obliged. Drilled through 1/4 inch soft steel with no problems. That's what I love about TS, they are always there when you need them

Rated 3 out of 5 by from Can't work miracles. I'm not an engineer so I didn't know what to expect. Drilled out some steel door handle rods really well, these had blunted lots of HSS drills. Tried to drill off the head of a striped wood screw and the bit was ruined, no impression on the screw.

Rated 5 out of 5 by from The best drills. Very good drills retain their edge longer than cheaper product. Use with cooling spray though when drilling metal.
