I am in a bit of a production mode, drilling out a number of Slimline blanks for future turning, finishing and assembly. I am drilling on my lathe.
In spite of going slowly, and backing out the drill often, I still am finding too much heat build up. (In fact, during the drilling of the Slimlines, I decided to drill a couple of longer 8 mm acrylic blanks. The second one, despite my best efforts, got sufficiently hot to 'stick' the bit in the blank. Had to cut if off!
I am drilling at a slow speed, and am using quality drill bits.
There must be a secret to aiding in the cooling process. I am presently using compressed air on the drill bit and in the blank when I withdraw the drill bit.
Do you have suggestions for what else I might try?
Thank you so very much.
