Review on Optimized Kempston Keyhole Cutter - 501011, Enhanced Cutting Diameter by Dan Reggae

Good price great performance. I cut a few keyholes in pine and this cutter went through with no problems. Better yet, you don't have to pre-drill a pilot hole as it (with light pressure) will do all the work by itself. I'm very glad I bought this beat. The plastic body is a nice touch.
