Which kind of lathe thread cutting tool do you guys use. I am in the market for a new one and can't decide what I want. I will only be threading stainless rifle barrels with this one.

Thanks and God Bless, Louis

HSS from www.arwarnerco.com

I use full form carbide for 90% of my threading now. Some Kennametal and some Mitsubishi. Cant tell the difference. Both work equally well.

Now we use the threading bits one can get from Brownell's.

Works great.

+1 to Rod. I personally use all Kennametal.

+2 for Rod. I have been using full form carbide inserts for a long time. Ba advised that they are TPI specific.

This is what I use too. I prefer the high speed steel for my threading whether in stainless or chrome moly.

I used carbide from Sumitomo.

I learned to grind my own threading tools back during my apprenticeship and used them for years. I now use the Warner inserts.

If you want to cheat, you can use 13 tpi carbide and just use wires or cut & check as you cut and you can make any thread you want as long as it's 60 degree.

The novelty of full form is that it cuts the crest or the point of your thread too and you can just check the OD as you cut. Once your OD is correct, everything else is correct. All of the old school knowledge of making and measuring threads is slowly being lost to CNCs and full form tooling. But that's OK too. If it saves time, it's better. Time is money. The first threads were probably cut with files. To hell with tradition, I'll take a lathe over that shit any day of the week!

That full form sounds pretty cool. I guess I am old school. Hadn't even heard of that but in my looking I had seen the cool looking inserts.

Thanks guys, Louis

I've been grinding my own since 1964 and still do.
Yes Cleveland Mo-Max rules.

Snap, exact year I started. Prefer the slower speeds of the HSS for the threads I do.
