CCMT 09T308
ISO Designation: CCMT 09T308
CCMT 09T308 uses the CCMT family's positive rhombic geometry, sized per ISO 1832 as 09-308, suited to lighter turning and finishing work.
CCMT inserts use an 80° rhombic positive geometry. The positive rake reduces cutting forces compared with a negative insert, which makes this family a common choice for turning slender or thin-walled components, and for finishing passes on steel, stainless steel and non-ferrous parts where lower vibration and a sharper edge are useful.
Per ISO 1832, the leading letters of this code indicate a 80° rhombic insert shape with a 7° relief angle; the remaining characters set the tolerance class, fixing style, size, thickness and corner radius.
