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!

    So you’re getting this tearout on the top?!

    That’s kinda nuts, never seen it before.

    Make sure your drill is sharp, and consider a brad-point.
