Review on LENOX Tools Bi Metal Arbored Technology Cutting Tools ~ Hole Saws & Accessories by Ryan Lawson

hole was already started with a smaller drill, so I moved slowly with light pressure. A few seconds later the fragile drill broke. When I took it out to insert a quality drill bit I noticed it looked weird at speed. I'm glad I didn't have a chance to drill with that horribly out-of-round hole saw.
