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

I am using it for drilling 3/4" holed in the roofs of the vans at work, installing NMO mounts for the business band VHF antennas. After 6 holes and 6 mounts, the drill was still working fine. The hole is just a couple thousandths too small, requiring me to feed the wire through the hole to get the mount in, instead of popping the mount in from the bottom like its supposed to be installed. Not a deal breaker but not the right size hole causing more work to be done on the job. Did the last 6 with my old bit and everything fit as it should've.
