Core Performance Benefits:
- Minimal Cutting Pressure: The R0.2 radius significantly reduces radial force, making it the best choice for preventing chatter in long-reach boring or on thin-diameter parts.
- Exceptional Surface Quality: Achieves a mirror-like finish even on gummy materials like 304 and 316 stainless steel by slicing through fibers rather than rubbing.
- Advanced PVD Technology: The PC9030 coating is optimized to withstand the thermal shocks of interrupted cuts while preventing Built-Up Edge (BUE).
- Precision Edge Sharpness: Unlike CVD inserts, this PVD grade maintains a razor-sharp edge, essential for clean cuts in high-precision aerospace and medical components.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |

Stainless Steel Pro-Tip: PC9030 vs. PC5300
Selecting the right grade for your stainless steel project:
Optimized for high-precision finishing and boring. Best surface finish and dimensional stability.
Better for semi-roughing, interrupted cuts, or when extra toughness is needed to prevent edge chipping.
Machinist's Tip: When using the R0.2 radius, ensure your machine has high spindle speeds available to maintain the recommended surface footage (Vc).
Packaging: 10 pieces per box.
