best drill bits

[Paul Baldwin]

There's a bit of a knack to it but it's not really that difficult imo, just needs an eye for the end result and a bit of practice. I've never even used a drill bit sharpener, just a bench grinder or even an angle grinder if stuck out on site and desperate.
I have found in the past that re-sharpened drills can actually be better than shop bought new ones, especially when you are using an electric hand drill.
