These 16-series CNC threading inserts cover 16ER external and 16IR internal types, represented by 16ERM AG60 with premium OP9125C hardened carbide grade. Purpose-built for hard materials and stainless steel, they match standard threading toolholders precisely with wide specification coverage.
The reinforced hardened coating delivers outstanding wear resistance and chipping toughness when machining hard steel and stainless steel, effectively suppressing built-up edges. They produce precise thread profiles with smooth surface finish and highly consistent dimensional accuracy.
Widely suitable for internal and external threading operations on CNC lathes, they cover common thread specifications for versatile use. Their extended service life reduces tool change downtime, lowers tooling costs and effectively improves overall threading productivity.
