Where can I find the “code” for indexable tips

[EmgeeParticipant @emgee]

Hi Andrew

From an earlier post, this may help you with insert selection.

Different tip radius, last 2 numbers in the code. 02=.2mm, 04=,4mm and so on.

First letter denotes insert shape, C=80deg Rhombic, D&K=55deg, R=Round, S=Square, T= Triangular, V=35deg.

Second letter denotes clearance angle. B=5deg, C=7deg, E=20deg, N=0deg, P=11deg.

Third letter denotes tolerances on thicknes and inscribed circle size, M denotes +or- 0,13mm for thickness.

Fourth letter denotes type, A,N,Q & W are flat top, G,M & T tops are shaped to provide cutting clearance and chip breaker.

First 2 numbers denote cutting edge length, 06=6mm on C shape insert, 07=7mm on D shape insert.

Next 2 numbers are insert thickness, 02=2.38mm, 03=3.18mm, T3=3.97mm, 04=4.76mm

Next 2 numbers are for nose radius, 02=0,20mm, 04=0,40mm, 08=0,80mm, 12=1.20mm.

The ISO codes sometimes have additional info such as PF for finishing or PR for roughing.

Does my head in as well one reason junked nearly all my Sandvic tools as didn't conform to an industry standard rather their own numbering unrelated to anything.
Seco, Iscar, Horne and Kennametal not much better they always make it hard to decipher as though it was top secret. Try finding the screw for a specific Kennametal tool and get sizes to buy else where, doable but takes needless time.

May find the better branded quality tips cut a lot better than the shops own branded chinese ones. Not only that last as much as 20 times longer no joke and false economy.
I only buy the cheapies when I cant get any decent branded tips, knowing what previous branded were like and comparing you get to know what the massive difference is all about. Must have 80 packs of 10 quality inserts some I will never use.

Thank you so much for the swift replies.

I'll be out in the workshop on Wednesday to check the holder id's, but those codes and the explanations sound about right I'm pretty sure I can get some quality tips now and keep making progress.

Cheers, Mike.

There is nothing wrong with making your own tool holders, and if you make your own it doesn't matter what the size or shape if you get some freebees go for it.

Anyone who comes up with the idea of selling a little illustrated handbook for all these tips is going to save a lot of these type of enquiries to say the least.

The type of abuse that normally does in all these tips is interrupted cuts or parting off centre. The tip in itself seems to be able to withstand a lot of wear.

There's not going to be much profit in it, so I wouldn't give up the day job quite yet. The "code" is a freely available international standard and all the manufacturers publish free technical data that spells it out in simple graphical format.

I can't be bothered right now but if you randomly pick one of the manufacturers and google their name plus "insert geometry" or similar you'll be there in seconds.

There are similar guides for the composition of the inserts. Many types are available including many designed for interrupted cuts. Describing the inserts as "carbide" is like describing something as being made of "steel".

Not so long ago, there was an article in MEW that covered it too…..
