Cobalt Pro Drill Bit Set (19 Piece) is rated 3.3 out of 5 by 11.
Rated 5 out of 5 by from HELLER HSS Drill Bits These are Heller Steel HSS Drill Bits, and of course that says it all really. A great addition to the Tool Box, which ensures that one can get the Job at hand done properly and with great precision. Thank You for a grest reliable product.

Rated 4 out of 5 by from Wanted to give 5 stars but... I really wanted to give 5 stars but the 3mm drill shattered on its first use and the 6 mm drill doesn’t seem sharp at all , I’ve used Heller drills for many years so I was a little disappointed All other sizes happily shot through anything I was drilling

Rated 4 out of 5 by from Good for stainless Used these to drill stainless steel. I managed to snap one drill but probably due to using a too fast speed. Larger and slower worked for me and once I got that sorted they were really good and held their edge.

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.
