Drill bits

[Ben-e-boy]

One of the first things I learnt to do as an apprentice and the only thing I can do left handed. Sharpen drills off hand.

I'm getting good at sharpening drills using an angle grinder when I'm on site lol. People look at me funny.

In actual fact though. Using a flap disk on a drill bit that already has nice even, not chipped cutting edges produces a surprisingly sharp drill.
