SPMT 09T308

ISO Designation: SPMT 09T308

SPMT 09T308 is an indexable drilling insert from the SPMT family, sized as 09-308, used in insert-type drill bodies.

SPMT inserts are used in indexable insert drills, typically as the peripheral or central cutting insert. Indexable drilling is common on VMC and CNC turning centres where hole-making needs to be fast and the inserts replaced quickly without regrinding.

Per ISO 1832, the leading letters of this code indicate a square (90°) insert shape with a 11° relief angle; the remaining characters set the tolerance class, fixing style, size, thickness and corner radius.
