best drill bits

[Danny Wideboy]

What about high quality screwdriver bits? Everytime I try and put together something that needs screws put in I end up knackering the head.

You need quality screws for quality driver bits or they will muller the heads every time. Cheap screws are single use, quality ones can be reused. 
Had a couple of drill bit sharpeners but never got them dialled in right. One just ruined my grinding wheel and all my drill bits. May have been an element of operator error.
