SNMG 120408
ISO Designation: SNMG 120408
SNMG 120408 is a square negative turning insert from the SNMG family, sized per ISO 1832 as 120408, built for heavy roughing.
SNMG inserts use a square (90°) negative geometry, giving the strongest possible cutting edge angle among common turning-insert shapes. This makes the family well suited to heavy roughing and high feed-rate turning on steel, stainless steel and cast-iron components where edge strength matters more than access to fine contours.
Per ISO 1832, the leading letters of this code indicate a square (90°) insert shape with a 0° (negative) relief angle; the remaining characters set the tolerance class, fixing style, size, thickness and corner radius.
