What’s everyone using for a single point threading tool?

[LoganHolt]

Just wondering what single point threading tool y’all are using on your setups.

Currently I have the AR Warner 3/8 HSS indexable insert threading tool and turning tool set.

Looking at other options as well, considering going back to carbide and running in reverse threading away from the shoulder.

Appreciate your thoughts and input. Thanks

Full profile carbide (I think that one is Iscar) in the correct direction.

I'll pop some popcorn

Kennametal Top Notch positive rake NTP3 inserts. Normal direction.

Get some positive rake carbide inserts for your holder and never look back. AR HSS is good, but don't get the mileage carbide provides.

I'm using the Iscar CutGrip TIP2. I like it because it has a low profile and doesn't take a up a ton of room compared to most threading tools.

I have had good results with quite a few carbide tools, lay down as well as top notch type. None of them are designed for how we use then so trial and error is in order. A sharp edge prep is important for low speeds.

please explain this? I’ve been using iscar lay down threading inserts @ 70-360rpm with good results but I’d like your opinion

Any speeds we thread at on a manual machine are slow compared to what most carbide tools are indented for. A lot of carbide inserts are not sharp, they are designed that way for high speed machines with a lot of power. They call it the edge prep on the insert. We benefit from a sharp edge prep for what we do. Its hard to find that info, its usually not in the grade information or the chip breaker info. You either have to call the manufacturer or just try a bunch of tools until you find one you like. I have a few of them but the seco cp500 grade is what I am using at the moment.

I've been using there HSS insert for years, worked good for me

I’ve had best luck with Carmex laydown bxc grade inserts.

I use various carbide inserts and get awesome threads most of the time. The times I don't is when the tool is dull or the setup isn't rigid enough. Carbide needs faster speeds so I do most of my threading at 310 RPM (which Gene Can't do with his setup, cue more popcorn).

Threading is a heavy cut toward the end which is very hard on inserts. Threading inserts will need to be changed to a new cutting edge more often than other inserts. Here are some threads I cut on a 416SS sizing die last week. They are dirty from use but were not polished at all.

I grind me own threading tools out of high speed tool stock.

Appreciate all the info and ideas guys thank you.

I use full profile inserts. Iscar, Carmex and Kennametal. Speeds anywhere from 300 to 700 RPM's.
If you are going to try full profile inserts I'd start with say a 16 TPI insert. Maybe 18 depending on actions you're barreling. You'll be able to it use on finer pitch treads as well. Just won't work as a full profile. You'll still have to turn the diameter undersize and polish the top of the threads.

This was taken in 2017. I probably have half-again more threading inserts now.

Arthur Warner stand up HSS insert.

Carmex makes a threading tool with a grade for slow speeds(90 rpm, and I use 70) on hard 400 series stainless, best I have ever used. These Carmex inserts are difficult to make dull.

I used to grind my own threading bits out of T15, Rexalloy, Tantung G, Armaloy 525, and Stellite(still have a few). The Carmex cuts just as slick a thread as the HSS and Alloy's.
