Cobalt Pro Drill Bit 6mm is rated 4.4 out of 5 by 35.
Rated 5 out of 5 by from Good value, not cheap. Good bit, great price. Drill bit is ground will and is strapped with hss. Co as my other cobalt buts are. This is much cheaper than other brand and seems to be just as good.

Rated 5 out of 5 by from cobolt I bought these drill bits to drill stainless steel. They do the job well if used with lube.

Rated 5 out of 5 by from Good drill bit for money. I purchased qty 2 because I was going to drill stainless steel and ome users have given mixed reviews about this item going blunt, but fear not. The secret is take your time and regular lubricant. I used WD40. Drilled 10 holes through 3mm stainless steel and still good.

Rated 3 out of 5 by from Some Good, some bad. Had to buy a few of the Heller Colbart drill bits to drill out 3 broken locking wheel nuts. 1st one cut great. 2nd was rubbish, didn't ptouch it and the 3rd was as the first. I used drilling lubricant as well. The 2nd must have been a dud !!!!. 1 out of 3 isn't bad but it should be 3 out of 3.

Rated 5 out of 5 by from Cobalt drill bit Needed a quality drill bit for drilling through steel. Purchased a 3mm & a 6mm to use to makke the pilot holes. Brilliant dells and went through the steel 10mm, like butter.
