If you are like me you have searched in every hill and holler to try and find a fine tooth hole saw for your tubing notcher. Go here http://kkind.com/Merchant2/merchant....egory_Code=SCF
It has 10 teeth per inch. Its what I'm using to make my suspension parts. g'day to y'all!!

 

Good, useful information. They're hard to find with more than 6-8 TPI. Sioux and Morse also make fine-toothed hole saws.

 

Note sure why you would need one? I have cut over 1000 copes with a standard Morse one. I have done everything from 1 3/4" all the way down to 5/8" and never come across a reason to change mine out. I just use the JD Square one and it works perfect.

Not as good as a Bridgeport but has worked good enought to meet every NHRA cert I have ever needed.

Here is the link to what I use. http://vansantent.com/tube_notcher.htm

 

I used to think I wanted some till I got used to using the coarse tooth ones, just keep the speed up and the feed speed slow and steady and they work great. If you really want a smooth cut though I’d look into a rotobroach.
