When buying your spotting drills pay attention to the overall length. Most of the ones that I have got have been really short and work great in chucks or collets. However, I needed some 82 degree spotters, had to get them from a different manufactor, and they are REALLY long. They chatter like nothing else in a chuck cause the stick way out. In a collet pushed all the way up they are fine. May end up cutting the excess off. |
