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

ok

Used to cut through wood.(2x4) Cut was good. Fairly easy to remove slug.

Absolutely the best hole saw bits out there. Runs through stainless like butter, cuts mild even easier. Highly recommend.

Ill leave it at that!

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 have always had good luck with Lenox products and their hole saws in particular. However once mounted to arbor these are rarely very concentric and leave you with a rough hole that is often slightly larger than advertised aprox 1/16inch. If you want a perfect clean hole I suggest either carbide hole cutter or size yourself 1/16 smaller with these and finish with filing, grinding, sanding, ect.. Overall these are great quick way to make a hole in almost anything! Takes alot of abuse to ruin one of these even in steel. Remember to use compressed air to remove chips often a d alternate pressure bird pecking on metals.

Cut straight through a 12 thick hardened steel vault in about 13 seconds. 10/10 would recommend

Building a set of speakers and needed to mount the tweeters. Seems I need and endless stream of new tools on this project. Oh well they will be useful later. Cut maple faced 3/4 inch plywood cleanly and fast. No issue over it not clearing the dust out of the cutting teeth. Didnt need to back it out once to clear it. Cant say that for another brand I bought.

Works good especially for the price, drilled 8 holes in 3/16th steel and still has all the teeth with plenty of life left.

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.
