Bosch2608587019 HSS-TiN Metal Drill Bit Cassettes

Needed to drill some Titanium which I managed to do well with set. Can’t vouch for longevity as only had them a short time but I have found Bosch drill bits to be of good quality though out my woodworking career.

Class drills still going haven't even had to take them to the grinder yet but I do use them at the correct speeds in pedestal drill or lathe

Used for drilling metal. Haven't used much yet so can't comment on longevity but are still sharp and accurate.

Great size selection

They seem very good quality and built to last, as i'd expect from Bosch Professional.

Only used a couple of these drll bits, they drill through metal quickly, how long a bit will last I've yet to find out.

Good range of drills

Bought these to use at home and work. Typical great Bosch quality item(s). Tried by drilling first with a HSS drill bit 3.5mm and was taking a while, so changed to a 3.5 from this set and drilled through steel very quickly and easily. I do think you have to let the drill bit do the work though and not put too much pressure on the bits. Came in a good case, I will only use a few bits at work and save the very small bits and a good few others for home. Have only used 2 or 3 sizes so far, but look decent bits and are doing the jobs well up to now !
