I’d really disliked the ragged edges of my pocket screw holes even though I’d reground my bit for better cutting. The battery drills I’d been using were maybe 1300 RPM at best. The cut from a corded drill was better but not what I’d hoped for. I didn’t have a 3000 RPM drill so I went to Harbor Freight and got a clumsy 3000 RPM clunker for about $10.00. The higher rpm made a big difference so If you’re not satisfied with the pocket hole cut with a slower RPM drill, try it with a higher speed drill.
