### ⭐⭐⭐⭐⭐ Do in 1 what others can't do in 30
*by M***. on 17 August 2015*

This drill bit did in 1 minute what others from Bosch and Dewalt couldn't do in 30 minutes using exactly the same power drill ( a £100 plus Dewalt corded machine) to drill out an M12 bolt that had split inside its holder - I'm amazed! I don't need a full set right now but I'll be buying one from TTP Hard via Amazon as soon as. Advice: use a grease. The only thing I would to have from the company - maybe it does exist but I couldn't find it - is a video showing how to re-sharpen the drill bit and for them to sell their own tool to do that
