Review on High-Performance EZARC Carbide Hole Saw For Cutting Stainless Steel And Sheet Metal - 1-1/8" (29Mm) Hole Cutter by Sanny Hoffman

This is a pretty good cutter. I’m rating the 5/8” version which I purchased and made 8 holes/cuts into 1/4 plate steel. As another reviewer noted, 1) you must cut at a slow speed specified in the instructions with the cutter, and 2) you must use plenty of continuous cutting oil including backing off the cut and putting oil right on the cutting surface throughout the cut, and 3) you have to use pressure slow and not rush the cut. If you don’t follow these simple instructions you will ruin the cutter and harden the area you are cutting making it impossible to complete your cut. I suspect that most of the poor reviews on this cutter is a result of improper cutting techniques. This cutter is comparable to the Greenlee cutters in cutting.
