This is what I used while drilling 3/4” dog holes in my workbench. I costs $21, but is well worth it. I was drilling Ash (Janka 1320 hardness) and found that I needed to respray at least for every other hole, but if I resprayed for every hole it seems to cut like butter.

ALSO, you should buy a good bit for the job at hand. Again, not cheap, but good. I used a 3/4” COLT Brad Point bit in a hand drill, since I did NOT have a big drill press. I built a bit template to help keep vertical AND correct spacing.

PLUS!.... Be sure to use a backing plate so that you don’t get blowout on the underside of the bench. You can see mine on the right side of the image. Everything is clamped securely every time.
