The Original Korloy CCMT060208-HMP PC9030 is a specialized carbide insert designed for maximum edge strength in stainless steel turning. While most CCMT06 inserts focus on fine finishing, the 0.8mm nose radius of this model allows for higher feed rates and better durability against mechanical shock. Powered by the industry-leading PC9030 PVD coating, it remains the top choice for preventing built-up edge (BUE) in austenitic stainless steels.
Optimization Tip: For ultra-fine finishing in tiny bores, you might need a smaller radius. See our Guide to Precision Boring.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT060208-HMP |
| Grade | PC9030 (The Stainless Specialist) |
| Nose Radius | 0.8 mm (High Edge Strength) |
| Coating | PVD (Sharp & Heat Resistant) |
Core Performance Benefits:
- Robust Cutting Edge: The R0.8 radius provides a significantly stronger edge compared to R0.4, making it ideal for removing the "scale" or hard skin of stainless workpieces.
- Faster Feed Rates: Allows for increased productivity (mm/rev) without risking edge breakage, reducing overall machining time.
- Anti-Welding PVD Coating: Specifically developed to stop stainless steel from sticking to the tool, ensuring a clean cut and consistent tool life.
- HMP Chipbreaker: Excellent for breaking chips even at higher depths of cut, preventing the "birds-nesting" of swarf in internal operations.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless 304 / 316 | 90 - 170 m/min | 0.08 - 0.20 mm/rev | 0.5 - 2.5 mm |
| Duplex Stainless | 50 - 110 m/min | 0.06 - 0.15 mm/rev | 0.5 - 2.0 mm |
Compatible Tool Holders:
Maximize the strength of this R0.8 insert by pairing it with a rigid SCLCR/L holder:
- External Turning: SCLCR1212H06 / SCLCR1616H06
- Internal Boring Bars: S12M-SCLCR06 / S16Q-SCLCR06
Stainless Steel Pro-Tip: R0.4 vs. R0.8
Choosing the right nose radius for your CCMT06:
Best for fine finishes and maintaining low radial pressure in small bores.
Best for semi-finishing or roughing where you need the insert to handle more force and higher feed rates.
Machinist's Tip: If your R0.4 insert is chipping during the first pass on stainless, switch to this R0.8 for increased edge security.
Packaging: 10 pieces per box.
