CCMT09T304 HMP PC9030 Carbide Turning Insert with TiAlN PVD Coating and HMP Chip-Breaker for Stainless Steel CNC Turning

The CCMT09T304 HMP PC9030 is premium PVD coated carbide positive turning insert specially developed for CNC external & internal boring turning of stainless steel. Equipped with professional HMP chip-breaker geometry and Korloy original PC9030 substrate grade, this insert features outstanding anti-welding & anti-chipping performance, stable cutting effect even under medium-heavy interrupted cutting scenarios.

Optimized for stainless steel semi-finish to medium rough turning, it realizes stable chip control, fine machined surface finish and prolonged tool life for long-duration CNC lathe continuous production.

• PC9030 ultrafine grain carbide base + TiAlN PVD coating, excellent anti-buildup edge & wear resistance for sticky stainless steel machining
• Exclusive HMP customized chip-breaker slot, ideal chip curling & breaking, effectively avoid scrap winding on workpiece or tool
• 80° rhombic positive rake structure, lower cutting load, reduce cutting vibration during intermittent turning
• Precision ground cutting edge, guarantee high dimensional accuracy and superior workpiece surface roughness
• Robust insert substrate, long service life for mass continuous & interrupted stainless steel turning operations

• Stainless steel (304/316 etc.)
• Carbon steel
• Alloy steel
• General ductile structural metals

• CNC external diameter turning
• Inner hole boring / internal turning
• Semi-finish & medium rough machining
• Interrupted cut turning for stainless steel parts

Combining high toughness PC9030 coated carbide substrate and HMP stainless steel-specific chipbreaker design, CCMT09T304 HMP PC9030 solves common problems like built-up edge and blade chipping during stainless steel machining. It ensures consistent cutting stability, reliable processing quality and lower comprehensive tool cost, being preferred turning insert for batch stainless steel CNC turning workshops.
