Holesaws

[CBR_Motorsports]

I was wondering what type of hole saws you guys use for your notcher. I have a JD2, and I want to get the really good ones that last for like 100 cuts.
Thanks

I like the Milwaukees. Be sure you get bimetal only.

DeWalt makes a good one also. When you decide what you want, I sell all types of shop supplies now, so PM me and I can get you some prices on them.

Kyle,
The trick it to keep them cool. Use cutting fluid or plain ol 30weight. I have over 20 clean cuts on a cheep Ace brand Bi metal. Even the pricey saws will burn up.

I've used almost every brand. I use only Lenox now, you can buy them at Lowes. They are easier on the drill and the adapter as well. I think the teeth are finer. Whatever you do, don't get the ones with slots up the side, they tend to hook the steel really bad. If anybody has stripped or broken the adapter for the holesaw, PM me, I have a way to replace it for cheap

Use Cutting oil......old 30wt and wd40 and those types of products are (lubricators) to fight friction.....even tho they have some "cooling" properties they are friction fighters non the less... your cuts and your tools will have better quality and last longer if you use cutting oils.......

thanks for all of the replies. Another Question--do you think wd40 is better or just regular cutting oil?
Thanks

Actually anything works. A zillion years ago, I used to use silicone spray...duh... I use WD40 when I am too lazy or out of the right stuff. Nothing works as good as cutting oil. There is no way you will save money by not using it. Just shop for a good deal on it. Sawing tubing is a machining process and has the same requirements.
A good hole saw can make hundreds of cuts even in 4130 if:
a) you use cutting oil
b) the cutter is held solidly and not wabbbling or chattering
c) the tube is held solidly so it does not wabble, chatter, or get caught
d) you use good steady speed and feed rates

Ya what he said........

Yup, slow down your drill press as slow as it will go, usually about 400rpm. and cutting oil makes all the difference. I bought a set of morse brand hole saws for like $60, sizes 3/4 to 2.5in.
