Hi there! I'm confused with this one... I've got these plywood squares that I had to drill a bunch of holes in. Despite using a low speed on my drill and adding masking tape (below) there's still pretty nasty tear out on nearly all holes. (EDIT: These are not through holes, this is for crochet square blocking boards. Metal rods which need to stay in place are put into the holes.)
And this is it after removing the masking tape.
What should I do? Thanks in advance!
Drill a small hole all the way through, then switch to the correct size bit and drill half way through from either side.
Try all the options everyone has mentioned to see what works best. There is no one correct answer that works for all situations.
