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!
First you should edit the title so it makes sense, then you could try clamping a sacrificial board (MDF, 1/4", dimensional, whatever's easiest) beneath and running the drill faster but moving slower. You might even try just going back to trying tape but changing your drilling method just to see if that improves anything before killing another piece of wood
Woops! I've fixed the title now. I'll give this a try, thank you.
