Review on 🔧 Maximize Efficiency with LENOX Tools' Bi Metal Arbored Technology Cutting Tools for Hole Saws & Accessories by Brian Trujillo

I just had to drill a 1 1/4 inch diameter hole in the rim of my new plastic sink so I could install a 1 hole faucet. I bought this Lenox bitten with a mandrel and fixed in his drill. The center and bottom of the saw were round - not "jumping" during rotation. Unfortunately, the serrated end of the saw is "cracked" a bit, maybe 1/16th of an inch - it looks like this end isn't quite round, but rather slightly elliptical. Since it was night and I had no other choice, I took advantage of it, but it didn't impress me.
