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 |
