Description
The Original Korloy CCMT120408-HMP NC3030 is a heavy-duty turning insert engineered for maximum impact resistance in steel applications. As a large size-12 insert with a robust 0.8mm nose radius, it is specifically designed to handle heavy roughing, large depths of cut, and severe interrupted machining conditions where edge reliability is the top priority.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CCMT120408-HMP |
| Grade | NC3030 (Maximum Toughness CVD) |
| Nose Radius | 0.8 mm (Maximum Edge Strength) |
| Application | Heavy Roughing, Interrupted Cuts, Forged Steel |
Core Performance Benefits:
- Ultimate Impact Resistance: The NC3030 grade features a specialized shock-absorbing substrate, preventing catastrophic tool failure during heavy interrupted cuts.
- High Metal Removal Rate: The R0.8 radius and thick size-12 geometry allow for aggressive feed rates and increased depths of cut, boosting production efficiency.
- Reliable Chip Breaking: The HMP geometry effectively controls thick chips during roughing operations, preventing chip entanglement and heat buildup.
- Edge Security: Best-in-class performance when machining raw material with hard "skin" (scale) or non-uniform shapes.
Recommended Cutting Parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Carbon Steel (HB180-280) | 120 - 260 m/min | 0.15 - 0.45 mm/rev | 0.8 - 4.5 mm |
| Alloy Steel (HB280-350) | 100 - 200 m/min | 0.12 - 0.40 mm/rev | 0.8 - 4.0 mm |
Compatible Tool Holders:
For maximum rigidity under heavy loads, pair this CCMT 12 insert with standard SCLCR/L type holders (Size 12):
- External Turning: SCLCR2020K12 / SCLCR2525M12 / SCLCR3232P12
- Boring Bars (Internal): S25S-SCLCR12 / S32T-SCLCR12
Quick Guide: NC3020 vs. NC3030
Choosing the right grade for your heavy steel job:
NC3020 (Wear Resistant)
- Best for: Stable, high-speed continuous cutting.
- Focus: Longer tool life in clean materials.
NC3030 (This Tough Grade)
- Best for: Severe interrupted cuts and vibration.
- Focus: Absolute security against edge chipping.
Machinist's Tip: This R0.8 NC3030 model is our strongest CCMT12 insert for roughing out steel parts with irregular shapes.
Packaging: 10 pieces per box.
