Carbide inserts.
mattinker:
Does anyone have a link to a simple explanation about carbide inserts. So far I've used high speed steel, brazed carbide tooling and some insert tooling that turned up with the lathe, Recently I bought a second-hand boring bar which I think is an early Sandvick, but I can't find any references to it on the web!
Any help would be greatly appreciated! Cheers, Matthew

Thanks Mark,
I've made some progress!!
So it's :-
A :- steel bar w/ coolant hole
25 ;- 1 5/6" ø
T ;- 12" long
S :- Screw Lock only
V :- 35°diamond
U :--3° endcutting
B :- 5° relief
R :- Right hand
16 :- 16mm?
I am assuming that the 16 is 16mm as the imperial units don't match.
Based on the table for inserts on the same site:-
The insert is a
V 35°diamond
B 5° relief
Tolerance?
H Looks like a 70° to 90° Countersink
I don't understand the code for the length which looks like 16mm
Thanks again Mark, I'm getting somewhere!! Cheers, Matthew

16mm is the length of one side .

Here are some charts with imperial measurements, from KBC Tools.
