I have an 8mm diameter boring bar with a triangular insert held in with an M2 torx screw. I want to buy some replacement inserts (and a spare screw) but after searching the web have only succeded in getting confused.
The inserts have sides about 7mm long, and the holder, made by Komet and marked UJ 8-803-F-R
Does anyone know the insert designation or maybe know if there is a Komet stockist in the south cheshire area.
TIA

Sort of replying to my own post here, but can anyone suggest where I can get a table or chart showng the make up of indexable insert identification codes?
I have just won an eBay item of 20 carbide tips which I thought (well they had the right 4 letter code) would fit another holder I have, only to find they are much too large, right shape though...

I've yet to try to identify the correct inserts for toolholders I've collected, but I was given a catalogue from Sandvik Coromant that appears to explain their numbering system with the aid of lots of useful pictures. Try to beg a copy from a local tool supplier.
There's probably something like it at
The catalogue also refers to ISO 1832-1991, so you might try getting hold of a copy of that.

Here's the ANSI identification system:

Thanks for the link the info looks great. However unless I am missing something the chart does not explain how the sizing works for triangular inserts.
Prior to looking at the site I had assumed the inserts standards would be ISO. I have just looked in the RS catalogue and their dimensions (radii) are given in mm so is there a metric ansi I wonder!!

Working from my Sandvic catalogue, first letter is shape. triangular = T ( w="bent" triangle ) second letter is clearance angle.. b=5, c=7, e=20, n=0, p=11. third letter is a tolerance, fourth letter is hold down type, single sided countersunk =T ( with top rake ) or W ( flat top ) next two is cutting edge length ( side length on triangular T, half side length on bent triangle W ) for T , 06=3.97, 09=5,56, 11=6,35, 16=9,525, 22=12.7 next two are thickness, next two nose radius next letter is edge type
I think you need T**(TorW)11.... tips.
The code is an ISO standard, ( which ??? )
Hope this helps.
I have another chart from sandvik. unable to send via your address please advise if correct'
Looks like my address got truncated. It is
