### ⭐⭐⭐⭐⭐ Cobalt drill bits

Quality sharp metal steel drill bits for the workshop. Bosch= Good Quality.

### ⭐⭐⭐⭐⭐ well worth paying a bit more for quality
*by G***N on 6 May 2025*

Normally use cheap drill bits but all the ones I had really struggled when drilling out a bolt. These ones made my life so much easier and saved me a lot of time. Always use a bit of cutting oil/spray when drilling metal and these are still sharp after use and hardly a scratch on them.
