The head of the pin chuck is unscrewed clockwise and the collet required is inserted.
Step 2 – Screw head back on
The head is screwed back on until it is about halfway secured.
Step 3 – Insert drill bit
The end of the drill bit can then be placed inside the collet and the chuck head fully screwed on to tighten the drill bit in place.
Step 4 – Insert chuck into power drill
The end of the chuck is then inserted into your power drill and will work just the same as with a larger drill bit.
Drilling with small diameter drill bits is no different to drilling with any larger size bit. Drilling at high speed is preferred, but it is fine to go slower just do not put too much pressure on to the smaller bit, otherwise it will snap.
