Top Notch threading inserts and tool holder

[urbanrifleman]

Recommended by Gordy. Cuts a gorgeous thread, at whatever RPM you want. It's designed for "slow" speeds. You can thread at 20RPM and get a perfect finish.

Thank you.

A chip breaker changes the rake angle to a positive angle.

Good to know. What would be the advantage of a chip breaker?

 

[urbanrifleman]

I went full profile 15 years ago and will never go back to a 60 degree insert. Never could get the same finish.

So you have a different tool for every thread?

 

[FireMedic]

Buy the one LVLAaron recommends. I run them on a carmex 3/4 16er tool. I thread at 200ish and threads come out perfect everytime

The a60 will let you thread real close to a shoulder without a chicken groove.

This one is fresh off the lathe today.

Is this a full profile?

 

[FireMedic]

Partial profile….all threads come out great. 16, 18, 24 TPI doesn’t matter

I tried the full profile inserts and it just wasn’t for me.

The full profile inserts do have a different feel to them. The ER60 is the easy button though. Like FireMedic said, no need for a chicken groove. I'd say these can get close to the shoulder than your upright tool, just due to the width of the tool.

Shop around for the insert. When I got them, you could get them individually on MSC. A 10-pack will last you an entire lifetime. I've yet to wear one out.. and I've cut all kinds of hard stuff with it.

It's pretty obvious after doing some shopping that particular insert has some Chinese knockoffs on eBay.

I'll get some from MSC

Buy a 10 pack from MSC when they run a sale and you’re set for life. I’ve probably got 100 barrels on my first insert and haven’t even rotated it.

I’ve been running those same BXC inserts for years. The do work very well for slower surface speeds. You’ll like them

 

[10XSHOOTER]

Check with Jim at Mesa tool. He has a insert holder to thread upside down and reverse on your Lathe. Only way to thread away from a shoulder!

 

[DaveTooley]

So you have a different tool for every thread?

yes I do. You can have one holder and swap out inserts. Get extra clamping screws. This is what I have for the Haas. I probably have double this for the Clausing Metosa.
One for turning
two for grooving. I use two different inserts in one. Square and radiused
one boring bar
six for threading
two drill chucks

I already thread at a minimum of about 200 RPM and I do tenon threads at 400. I'm not sure how much faster I can go.

I thread at a 500-900 rpm with all the carbide inserts I’ve tried.
I’d go faster but vibration becomes an issue if barrel isn’t super straight.
I’m just a hack but going faster made a world of difference with carbide.

I really like the full profile inserts, cut and hit it with cratex and done.
I can blast through brass in just a few steps and spring cuts with them and get good results and not have to file tops down on our fishing rod butt cap studs

I use a carmex 16ER holder, no complaints whatsoever.
The exact one listed.
Then just swap out for 16, 18, 20, 24 and 28 TPI full profile inserts.

I've never found it necessary to polish the top of the treads since I went full profile. When I use a standard 60 degree insert for threading I always turn the OD 5-10 thou undersize. It leaves a nice flat. No file needed. In fact you had better turn the OD smaller. If you don't you're depending on the mating threads to be perfect. The threads will have a radius in the bottom that will interfere with a sharp topped thread and inserts do wear and chip. When I did things on a manual machine I knew when to start checking the fit by the width of the flat on top. I could get to within a pass or two before checking.

Yep
As soon as see top form I start checking plus I dial in total needed cut on cross slide and when my compound is close to 0 I’m close as w second indicator.

I struggled a bit when I started using carbide but after learning some of the things carbide wants I wouldn’t go back to HSS or standard 60 degree universal.

Left insert is flat on top. Middle insert has a K chip breaker, the right insert also has a K chipbreaker. It is just adding positive rake in these inserts.
