This is a mini tool post, and works great on a mini lathe. So it should oughtta be able to use the carbide just fine if you have the power. I have an 11" lathe Emco-Maximat Super 11 and I have never used anything but indexable tooling. You can get an idea of where to begin on the Dorian web site, however, the subject is wide and deep. If you look at the Mitsubishi Carbide web site you will see an entire universe of inserts.
I found a local tooling vendor that sells to many machine shops in the area. Also, the insert vendors each have very capable people that are typically willing to come by and spend time helping you even if you have a home shop. I have found that you do need to use different inserts for different metals, etc, but when you get the right insert you don't need to polish anything because the finish is just perfect.
For cheap insert holders for a small machine, take a look at this. I would break down and buy a FEW insert holders. Get some or size holders. Join Date Feb Location latrobe,Pa. Usually cheapest of all. As for the T just run it slow. Even though I manufacture and sell indexable inserts out T I have to tell you Carbide would probably work better for hardened steel. Boy that's hard for me to say. Oh well good luck Mike. Thanks for all the feedback. What is the difference between these two type of inserts?
Are 'T' and 'M' for different types of hold-down screws? Also, if I think I can turn pre-hardened steel with this, I'm I going to have to go to a flood or mist coolant system, or can I get away with dry? I understand brushing-on oil is a bad idea with carbide. Thanks again! If you get a cheap holder set whatever you do don't get the ENCO "import" or its equivalent. The ENCO is cheese steel garbage with what look like hand-cut seats that don't even properly fit the inserts. Went straight back.
I should have known better. For steel a better choice is a holder with a tilted seat like TNMG. The insert itself has a positive rake, and a flat edge i. They are meant for use in a tilted seat that provides the relief and brings the rake angle closer to neutral. The flat edge means the inserts can be flipped over, you get 6 corners instead of 3. Gord For a screw down insert, the difference between a "M" and a "T" usually means 2 things.
First a "M" does not have chip control chipbreaker , and second it is not ground. The "T" has a chipbreaker and is ground. Both are 60 degree countersinks with the same through hole. Sometimes you will see a "W". This is usually ground but no chipbreaker. Not to confuse the issue you can also have a "B". But this represents the older hole and countersink combo for flathead cap screws.
If you can, get a Valenite screw down insert catalog. Most Insert manufacturers run pretty close to this chart. Hope this helps. HSMike, what does it mean to say that the "M" means not ground? TCMM is ground and has a built-in chipbreaker.
Handy photo: I recall figuring out some years ago that the TCMM is an oddball that does not fit the regular nomenclature. Also uses a screw with a conical profile head that does not fit any other inserts in my kit.
