Rated 2 out of 5Â by JamesO A little disappointed
After the last drill bit in a previous (different brand) set finally gave in I decided to purchase some more metal drill bits. As I have a fair amount of Bosch tools that have lasted well I thought I would give these a try. Unfortunately the 4mm drill but broke (as in shattered into many pieces) going though 0.9mm steel. They did feel good quality and for the 0.5mm I got out of it it was fantastic... The sales assistant behind the counter was as surprised as I was that it had broken so badly being a Bosch product. Maybe it was just my luck it was a bad batch, who knows!

Rated 1 out of 5Â by ANOTHERDIYDISASTER Misleading
With words like "X-Pro" and "Metal" used to describe this product, I was disappointed to have the drill bit literally melt, smoke, and change shape - obviously I have no idea of the tensile strength of what I'm drilling, so have no understanding if I'm pushing this product beyond it's capability. As a home owner doing straight forward DIY I'm simply drilling a hole through what appears to be an existing 5mm steel fence post support. My recommendation is to consider other products before wasting your money on a one hole drillbit.

Rated 4 out of 5Â by kl000000 Drilling into metal lintel
Had been trying for hours to drill into the metal lintel to install wooden blinds in our new build but had no luck. Managed with this set but still wasn't easy. Worked my way up by 2mm bits at a time and eventually got there, but each hole took about 5 mins of drilling in total - not a quick job. Used a cordless drill, on a low setting and switching to hammer if the bit got stuck

I use bosch power tools but made sense to use their drill bits.
I had one whole to drive on the metal support on the bottom of my car.
I first used a small drill bit size 3 or 4 can't remember anyway all went fine and I cut through the other side.
I then moved to a 5mm bit and it snapped in 3 places as it went through the other side.
Thankfully because it went through I was able to knock it out the way with a punch.
I then got another drill bit not bosch and used a 5mm without issue I then went to a 6mm bosch bit and it also broke in 3 places.
All in all great cutting drill bits but not strong enough.
