Reviews
Cobalt Pro Drill Bit Set (6 Piece) is rated 4.2 out of 5 by 46.
Rated 5 out of 5 by from They do the job you need - go slow! Bought a few days a go to drill the head off a Spax 5 x 50 that I had used to secure a cushioned seat in a rebuilt dining room chair. The screw had gone off at 10 degrees due to a fixing bolt that was too long being in the way and could not be reversed out. Had used 4 different normal HSS drills and it was taking too long. Used the 8mm to reaffirm the pilot hole then 10mm to drill off the head then twisted the 3mm of screw coming through the other side with a pair of pliars. Trick is to drill SLOWLY with some cutting fluid (3in1 will do) and if you feel the drill bite and pull STOP and reverese it and try again with less pressure -it wont snap. Saved me a decent amount of time (hours v 5 mins)

Rated 2 out of 5 by from Ok but went blunt fast I bought these following reviews and initially I thought they were great but even with drillimg fluid and not letting them overheat they have already gone blunt. For the price I expected better.

Rated 5 out of 5 by from Solid drill bits Used these to drill a rounder disc retainer bolt on my car. Drilled through it like a knife through butter and did the job really well. Always useful to have.
