I bought some 'wood' discs that are about 1" in diameter. I want to drill a 1/4" or so hole in the middle of the disc. Using a 1" forstner bit I drilled a depression in a piece of MDF for the disk to sit in. The disc fits nicely in the depression and I don't have to worry about holding the disc. I tried drilling the middle hole with a 1/4" bit. The drill started nicely but then the disc started spinning and burning the mdf and itself. The disc actually spun onto the bit as the bit was raised up. The hole was a mess. I tried changing to a 1/4" forstner bit hoping the outcome would be different but it was the same.
Other than holding the disc still somehow, is there a way to resolve thie problem? Change the speed of press maybe?
