The ones we bought from Relton were very expensive, and sadly the plain jane hole saws form Home Depot seemed to actually last longer when used in the notcher.

Now, when used to drill a straight hole in flat plate, in a drill press, they kick ass.

I'm interested to see what your testing turns up since finding a deep hole saw to replace those that Trick Tools used to carry seems to be on all of our mind.

I know, its a long shot. We are a Relton dealer and I have tried one of their saws and the same thing happened. And yes, one-off mfr'ing is expensive. Also the price of these is getting into machine tool territory, which makes it tough unless your a commercial shop.

The problem with the regular long hole saws (like jmr's) is that they don't last any longer than a regular hole saw and they were double the cost. I heard they were buckling under load cause the walls weren't thick enough or just too long.

There are lots of ways to notch tube though. Seems you either pay for a machine, or gobble up labor, abrasives, and/or hole saws.

For vertical holes in plate or tube, these things are kicking-ace. One of my fire sprinkler fabricators stopped counting after drilling 350+ holes in .125 wall pipe..vertically in a press.

Getting more of these in a couple days.

We still have kits and singles

We will post up some "shorter" saws soon, for 3/16" plate and thinner.

Tom I finally got to use my 9/16" hole cutter and WOW!!!!! I feel like an idiot for not buying one sooner. This will literally save me hours per week compared to using regular hole saws. And it is easier on my drill press since it doesn't seem to "catch" so easily. Thanks for the recommendation!!!!

Thanks Dj. I have to admit these are not for every application where you would use a hole saw of large drill bit. But they do have an extremely long life and make really nice holes.

Wow, we went through a lot of these in the last week and a half. We appreciate the business.

I think mine has finally gotten dull. I would estimate it did 200 holes, maybe more, in 3/8" and 1/2" material only. The pilot bit itself is still sharp, but the cutter isn't going through like it did before. Time to order another!

Thanks Dj, thats the most popular size for the pbb crowd.

Using these is like cutting through butter!

Got my 3/4" bit today along with some other goodies. I will probably drill a hole or 2 tomorrow just to try it out

I will report back about the performance of it! Thanks!

Just purchased another one of these cutters in the 1 3/4" flavor. I have already purchased 4 in different sizes a few months ago and they work great. Since I now have 5 I was wanting to buy a case too but I didn't see just the case listed on your website.

Ohioyota - next time you order, let me know and I'll get you an empty kit. I have tried numerous times to buy empty kits but they wont let me
