These Zhuzhou CCMT diamond-shaped internal turning inserts come in CCMT060204-HM specification with YBC251 and YBC252 coated carbide grades. Specially developed for steel workpieces, they fit standard small-bore internal turning toolholders precisely.
YBC251 and YBC252 grades deliver targeted wear resistance and impact toughness for different steel machining scenarios, effectively suppressing built-up edges. The optimized HM chipbreaker ensures smooth chip evacuation in small bores, achieving fine surface finish and stable dimensional accuracy.
Ideal for internal turning of steel parts on CNC lathes, especially small bore machining from roughing to finishing. Their long service life reduces tool change frequency, lowers tooling costs and effectively boosts overall machining productivity.
