Another Stripped Counter shaft :(

[fazersharp]

I'm using a Heller (German) Cobalt bit, so would have thought the quality would be fine?

However I am using a 12v hand drill which is possibly not the best? Would have though a drill is a drill, as long as it turns what more can it do  :\


I'm very tempted to put some lock-wire through the holes of the circlip and leave it at that at this point  :lol

Ive got those I have this set - http://www.toolstation.com/shop/p94153?table=no
My problen when drilling anything other that wood is that they are all blunt now.----------- Next question
(I will start a new thread in the general section as not to de-rail this one )
