ISO turning inserts follow a standardised shape and size code, so an insert from one manufacturer fits a holder built to the same ISO code. We stock 18 of the standard ISO shapes — CC, CN, DC, DN, KN, RC, RN, SC, SN, SP, TB, TC, TN, TP, VB, VC, VN and WN — plus Carmex's 06IR Turn ground insert, in carbide grades for turning steel, stainless steel, aluminium and other common workpiece materials.

Inserts are supplied by Vortex, Palbit and Omega. Once an edge wears out, most inserts can be indexed to a fresh cutting edge rather than resharpened, and boring bars and turning tool holders below are sized to take the same ISO codes.
