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

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 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 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 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.

Great price and a good addition to my set of Lennox hole saws. I've been using these hole saw for cutting wood, plastic and metal and have had good results.

I had to purchase a specific size to cope some angle iron (stainless steel) for mounting against some stainless tubing. I was told the stainless would work harden, etc, but no fear, take it slow (60rpm), with lots of pressure (and a little lube) and the hole saw made 24 cuts through 3/16 stainless without issue. The cope fit the tubing nearly perfect, just a quick die grind of the edge to remove a small burr, then a wash, and it was ready for TIG welding.It definitely helps to have a rigid setup, and would suggest a tube notcher if the budget allows. I've modified mine to accommodate different types of stock material, which saves considerable time and cost over using a milling machine.I purchased 2 of these just in case. I never opened the second box, and the first is nearly as sharp as new, without a single broken tooth. I've always had the best luck with Lenox hole saws, and with the amazing price on this site, they are actually a really good deal.
