Internal Threading. What Single Point System To Buy?

[Crafted]

I'm thinking of buying a boring bar with index-able insert for single point threading. I'd like to know your thoughts as to what brand to buy. I would pay the price for a used USA brand. However, I'm unsure of which insert systems are more popular and which are to be avoided. I'm concerned about a good working tool and a tool that I'm likely to be able to buy inserts well into the future. I'd also like to be able to buy a wide range of inserts. Looking forward to your opinions.

I have one of these in 1/2" does id and od threads. you can get hreading and groving inserts for it. Arthur Warner also sales HSS inserts to fit it also.I need to get some HSS inserts soon, haven't gotten around to it.

kd4gij,

It seems there are different insert systems. I'd like to make things to fit my Atlas spindle. I've got the Bostar AXA tool post system. What brand bar and kind of inserts does it take?

I studied that site. It helped to me understand these tools more.

there must be a good reason for not grinding your own hss or cobalt cutting tools ? i always thought carbide was for high speed / higher horsepower / deeper cuts than most of our hobby machines are capable of doing, did i not understand correctly ?

I can't think of one.

Carbide will work fine on most hobby class machines, but you may not be able to take full advantage of it's capabilities.

Only lathe I have owned that didn't do very well with carbide tooling were my 7x machines. All I run on my current lathes is carbide (SB 8k and PM1340GT). But then it could be I'm just too lazy to grind tooling when my indexables are just too easy to use.

Crafted, while I understand your concern about getting a tool that you will be able to buy inserts for in the future can I possibly add something. For a hobbiest you got to ask yourself how much internal threading you are going to do. I bought a no name brand internal threading tool just recently and a tray of 8 inserts. I can honestly say I think these inserts will probably last me the next 20 years.

Remember internal threading is a pretty light operation and you don't take off all that much material so tool wear is going to be slow. Factor in the number of times you will do an internal thread and finally consider that each insert had three sides......
