Get longer tool life, superior surface finish and less downtime with the Korloy CCMT060204-HMP (Grade NC6315) – now available at CNC Tools Depot.
Unlock next-level productivity with the Korloy CCMT060204-HMP (Grade NC6315) – engineered for high-performance machining of cast iron and general engineering components.
With a true negative ISO geometry (CCMT 06 02 04) and the proven HMP chip-breaker, this insert delivers outstanding stability, less chipping and longer tool life. The NC6315 grade is a CVD-coated K15 grade, designed for heavy interrupted cuts, high feeds and challenging cast-iron workpieces (both gray cast iron & ductile cast iron).
Expect better surface finishes, fewer insert changes and a lower cost per component thanks to the robust coating, optimised edge design and wide application range.
Ideal for turning operations in automotive housings, aerospace fittings, die & mould work and general engineering. At CNC Tools Depot, we stock this best-seller and offer competitive bulk pricing across India.
“Cut costs, not corners — Run longer, cut faster, change inserts less often!”
Geometry: ISO CCMT 06 02 04 (negative-style turning insert)
Chip-breaker: HMP series (for medium-to-heavy turning)
Grade: Korloy NC6315 (K15 class) — CVD-coated for superior wear & chipping resistance.
Application: Primarily turning of cast iron (gray & ductile) — also fits general engineering tasks including interrupted cuts and high-feed machining.
Because real-world machinists see fewer insert-changes, less downtime and dramatically improved surface finish. The NC6315 grade’s coating and edge design minimise flank wear and edge chipping even under unstable work-holding or heavy interruption
Automotive (engine blocks, housings, casting components)
Aerospace (cast iron components, structural parts)
Die & Mould (cast iron fixtures, mould bases)
General Engineering (gyms & reducers, pump bodies, grey/ductile cast iron parts)
The NC6315 grade is built for cast iron machining (both gray and ductile). It handles high-feed and interrupted cuts well, thanks to its robust coating and chip-breaker design
It is typically used for turning operations (negative style insert CCMT geometry). With HMP chip-breaker it handles medium to heavy cuts, high feed, and even interrupted surfaces.
Because NC6315 offers higher wear and chipping resistance, which reduces insert-change frequency and downtime, leading to lower cost per component and better surface finish.
"CCMT 06 02 04" indicates: C (80° diamond shape), C edge tolerance class, M (7° clearance), T insert style, size “06” inscribed circle approx 9.525 mm, thickness “02”, cutting edge length “04”. HMP is the chip-breaker style for medium/heavy turning.
