Review on Drilax Tungsten Carbide Stainless Discharge by Brandon Rogers

Ordered a 3/4 inch hole saw for precision. Got a 20mm hole cutter. Although the 20mm hole cutter is a little under 4/10000 of an inch more, I ordered it to avoid the oversized hole that usually results when using a hole saw for thinner materials. Used it anyway and found the carbide teeth are thicker than other similar cutters I own. The extra thickness requires a lot more cutting fluid and drilling effort, even in 1" to 8" material.
