Hi,
I have noticed that when I drill 27/64" holes, I always end up with a gap on the side that the drill enters.
I drill on the lathe and make sure to clear the bit every 1/4" or so and to let it cool after about 1/2" to 3/4". I will test the bit for heat when I clear it.
But even after doing this, I still get this space between the tube and the blank. This only seems to happen with the 27/64", 7mm and 8mm are fine.
As usual appreciate any help.
Thanks
Steve
