Keyhole bit usage
Iím in the process of cutting about 20 keyholes. I was into the 3rd (1 inch long) keyhole and the bit basically fell out of the collet (on a Colt) almost converting the piece to scrap (it didnít go through and I was able to repair it).
I know I tightened it well and the collet ďlookedĒ clean and no, it wasn't bottomed out (I always double check this). Needless to say, I will be cleaning the collet and bit before the next attempt. I may try sharpening the bit, but itís a small Freud bit and I have a replacement on the way.
So my question is Ö the bit was too hot to touch at the time, was this (the heat) the reason the collet loosened? That has never happened on this router before and itís a pain to check / re-tighten (I have to take the router out of the plunge base, and it fits tight).
I wasnít forcing the feed but may not have had the RPMs high enough. Iím cutting mostly Red Oak, but Iím not looking forward to the couple pieces of White Oak and Maple. Any processing advice or things to check for would be appreciated Ė Iíd rather not melt down my new Whiteside bit after 3 cuts.
