Lenox Tools - 3002828L LENOX Tools Bi-Metal Speed Slot Hole Saw with T3 Technology, 1-3/4

I use these in my tube notcher. I have used the same cutter to cut notches in schedule 40 pipe and 1 1/2 tubing and it just keeps going. No problems with broken teeth and it seems to stay sharp for a lot longer than I expected.

I burned the teeth off this size in my Lenox hole saw kit, and this is the replacement. They modified the plug removal slots on the side so its even easier to clear the plug out. (I got a diamond hole saw for stucco in the future.)

These are pretty good quality and last if taken care of..

Works well, Lasts long time.

Get it??? All the way around... HOLE SAW. Okay so its a bad joke, BUT its a great hole saw being a Lennox.

I had a cheap hole saw from a big box. It was better at burning wood after only a few cuts. This frustrated me and made me angry, as I was wasting my time, and ignoring my own best advice to get decent tools. So I ordered this with two day delivery, got it in one, and finished the job with absolute ease. I have since gotten a couple more of the Lenox hole saws in different sizes, and they have all delivered great performance. The speed slot also seems to make plug removal from the blade easier. So far so good on the durability; time will tell.

I have ten of these hole saws. I like them and I did not have this size so I bought it. they work great.
