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!
I hadn’t considered the quality of the bits, but that’s a fair point. These are from sets that are probably $25 max, I’ll be sure to grab some higher quality ones, I didn’t realise that would have such an impact on something like drilling holes. Thank you.
No problem! I think you could probably still improve performance with a scrap piece and good clamp pressure before you’d have to spend any money. Good luck!
