Hi
We are looking to either pick up an other knock out set or a carbide hole saw set. We have been using the ideal type up to 1" and love them they make a perfect hole with no wobble and last a long time. I was wondering if anyone has used the larger sizes 2" - 4"

We have the quick change set at work up to 2" I wish I knew about these back when I was contracting as they are the cats meow for knocking out holes in cabinets as long as you have room for a drill, the first time I used it I couldn't believe how smooth it cut, and there is a ridge to keep it from going all the way into the cabinet, the pilot bit has a slightly larger cutting head so the slug doesn't hang up on it as there is a spring that pushes the slug back out of the hole saw and you just pull it off the pilot bit, they also cut very fast and we use a little cutting oil on them when we use them for stainless steel cabinets, I have never used a faster cutting hole saw on stainless which in the steel mil most of our box's and disconnect are.

I was sure they were made by Kline as they are in a black/dark gray plastic case which has 6 cutters ?" thru 2" with 3-?" pilot bits, and the quick change mandrel that has a ?" hex shaft, I just couldn't find them on the Internet anywhere or on Kline's web site, the picture below is a Greenlee but is exactly the same shape, number of cutters, and the quick change is the same kind, but with the case being a dark charcoal gray or black it doesn't seen like it is, I will try to get over to the tool room to check it out when I go in Tuesday, I know the manager of the tool room told me they cost over $500.00 per set but he could have been quoting the list price?, maybe they are Greenlee but as with Kline I couldn't find the set we have on the net, and the fact the case was not Green like most of Greenlee cases are.

But even at $500.00 to me they would be worth it for the way they cut and how long they last and if you do allot of stainless then they would be a must, and they are faster then using a knock out punch

This is exactly what they look like, this is a photo of the 1" one

Note the ridge at the back of it that keep it from going all the way into the cabinet and hitting something.

I will say that for tight places you will still need a good knockout punch set also because you can't always get a drill into some places.

Wayne, I'll bet it's the Ideal TKO set that I have:

http://www.idealindustries.com/prodDetail.do?prodId=36-314&div=3&l1=saws_drill_bits&l1b=tko

Under $250 on Amazon. They're great for everything I've used them on. The ones I have tend to wander slightly more than the Greenlees I tried, but I'll take that since the Greenlees didn't have the spring to push the KO out.

The set we have the saws only have 4 cutting edges and are quick change type, they look exactly like the Greenlee in the photo I posted, they do have the spring on the mandrel that pushes the slug back out also, it is removable so maybe someone removed it?, I'll find out when I go back in Tuesday.
