Lenox Tools - 3002222L LENOX Tools Bi-Metal Speed Slot Hole Saw with T3 Technology, 1-3/8" SEE PICTURE

My 1" lennox bit is shot -- I was going to buy a cheaper version but noted my last Lennox had lasted 20+ yrs with abuse so I got the same. It fit existing bit holder and worked great on first use. The clean out design on this one works better than the old one.

sturdy and well built.

Good price and high quality

I do the purchasing for a HVAC and Plumbing co. and these hold up better than any other brands that we have tried.

I was part way through running some plumbing vent pipe through multiple studs when my other 2 1/4" saw got too dull to continue. It is fairly old now. Popped this one on and got back to work. Only it has fairly fine teeth, and they would be great on a finished wood countertop where you don't a ragged edge to you cut, but in doing rough-out work I'd much prefer a hole saw with more aggressive teeth.I did finish up what needed to get done that day, but it was a lot harder work than was necessary.. And with about 15 more holes to drill I think I might look for something else, or use one of my larger hole saws and shoot some foam insulation in to hold the pipe in place.

I have always loved the Lenox hole saws. This one has done the job once again.

Quality hole saw. Cut through 18 gauge sheetmetal like butter.

I needed a size that was not in my local hardware store. This was a good price and came to me quickly. I do recommend it.
