Cobalt Pro Drill Bit Set (19 Piece) is rated 2.9 out of 5 by 8.
Rated 1 out of 5 by from Not good. Snapped 3mm & 5mm in minutes Not good at all. £38 wasted! Not happy at all. I was only going through mild steel 1.5mm

Rated 5 out of 5 by from Buy cheap and struggle. You get what you pay for. If you want a hole with minimum energy loss from you’re battery, buy this set!

Rated 4 out of 5 by from Saved me time I used slow speed and plenty of lube. Went through the first couple of times without an issue. However after a few uses they are starting to blunt. However ordinary drills would not touch this bar

Rated 5 out of 5 by from Used these for years These last well with the Cobalt coating. We have tried lots of drill sets and these are best we have found as they last far longer even if you abuse them a little. Have used them for many years but lets face it they are a consumable!!

Rated 1 out of 5 by from You get what you pay for You've sent me a mail asking me for a review. I wouldn't normally write a negative one, however .... The reason for buying this cobalt drill set was that my own HSS drill bits weren't up to the task. Understanding that theses are cobalt and therefore brittle, i used with care. Two snapped off and 70% of them were blunt within 3 mins of use. Pretty poor show i'd say.

Rated 1 out of 5 by from Sort of good BUT. On it first use the cutting edge broke on four of the bits whilst drilling combination of brass/steel inserts (a lock) purchased for cutting stainless steel bit (no pun intended) disappointed with the performance particularly on softer steel.. and yes I used cutting lubrication for the record. Can supply photos if needed...

Rated 1 out of 5 by from Poor quality set Not really up to the job and blunt very quickly, standard drills lasted longer on the material
