Post subject:  Bridge slot problems

I was cutting a slot for the saddle with a Bosch Colt, and the bit got pulled into the slot. It was well tightened and I was taking light passes. The wrong kind of end mill? Upcut? Downcut?

Any thoughts would be appreciated.

Thanks in advance.

When you seat the bit in the collet, back it out 2mm so that it isn't bottomed out. A bottomed bit will not tighten well, on occasion. If there is any glazing on the shaft of the bit, clean it with blade cleaner.

Did the bit get pulled down into the slot, making your slot too deep, or did it catch on the side of the slot and take out a divot on the side? If option 1, Alex is correct. Don't bottom the bit in the collet. If option 2, then, umm...hold on tighter!
