Guys while I have not conquer knurling yet but I am making some progress.Next on my list is threading,which my first try the other day was a failure.So I went back and read several post of others asking questions.Well I have not made it to grinding my own cutters yet,I would like to purchase a threading tool holder that takes the insert type cutter.I watch a Utube where a guy is using one that Shars sells but he did not say much about the inserts.What I was wondering if others here uses this threading tool and if you like/dislike it and what you would recommend in place of it?And what insert,there is three choices but they look the same,http://www.shars.com/products/index...ol-universal-external-threading-tool-holder-1
I really don't think that I will be threading that much and with my short memory I think that the insert type threading is a better fit for me.Guessing that I would be threading maybe 1/4-1/2 in fine/course threads.Thanks for some direction or links----kroll
 
I prefer a vertical insert type (MVTO) for external threading, as one insert (TNMC/TPMC) can be used for the range of threads you indicated (8-36), the lay down type require a different insert for various TPI and can get pricey. I have found that cheap inserts break easily, so I try to purchase higher quality (like Iscar) inserts. I have no difficulty doing a wide range of threads with these inserts, each insert has 3 cutting edges. I use the TPMC (positive rake) inserts in softer materials like aluminum, the TNMC in steel, SS..., otherwise just get a TNMC to start.

Thanks guys,for the suggestions,I sure like the ideal of just using one insert for8-36TPI to cover all my threading.I see that the type I pick out requires different inserts,thats not so good.Some of the material that I want to use is stainless steel 303 maybe 316 so I think carbide maybe would be better?I have read several post here where some say HSS is better then others say carbide is better.But its for threading and SS so I guess both would work?
 
I had a Shars internal indexable threader and was not impressed. The A.R. Warner kits are very good. They have HSS and Carbide available too. I used the Warner HSS tool to finish a project that the Shars tool couldn't do. It cut 304 stainless like butter on a hot knife.
 
I've got four of the AR Warner kits (turning, internal/external threading, boring) and am very pleased. The range of threads with the #18 is 8-36 TPI also in case you didn't notice.
