Our HRC56 Corner Roughing End Mills are engineered for high-efficiency roughing in hardened steels (up to HRC56), stainless steel, titanium, and other tough alloys. Featuring a robust corner radius design and advanced flute geometry, these end mills deliver exceptional material removal rates (MRR), extended tool life, and reduced vibration-making them ideal for aggressive roughing in demanding applications.
Key Features
High Hardness & Wear Resistance - Made from ultra-fine grain carbide with a specialized coating for machining materials up to HRC56.
Corner Radius Design - Strengthened cutting edges reduce chipping and improve tool longevity.
Variable Helix & Pitch - Minimizes harmonics and ensures smooth cutting action.
High-Efficiency Roughing - Optimized chip evacuation and reduced cutting forces.
Multi-Layer Coating - Enhanced thermal resistance and lubricity for prolonged tool life.
Technical Specifications
| Parameter | Details |
|---|---|
| Material | Premium submicron carbide with TiAlN/TiSiN coating |
| Hardness | Suitable for workpieces up to HRC56 |
| Diameter Range | 4mm - 20mm (standard), custom sizes available |
| Shank Type | Straight shank, Weldon flat, or cylindrical |
| Flute Count | 4-6 flutes (optimized for chip clearance) |
| Helix Angle | 35°-45° (variable for reduced vibration) |
| Coating | Nano-composite coating for heat resistance (optional AlCrN for higher HRC) |
| Corner Radius | 0.2mm - 1.0mm (reinforced edge geometry) |
Performance Advantages
1. Superior Roughing Efficiency
-
High MRR (Material Removal Rate): The unique flute design allows for deeper cuts and faster feed rates, reducing cycle times by up to 30% compared to conventional end mills.
-
Reduced Cutting Forces: The variable helix angle prevents chatter, enabling stable machining even in hard materials.
2. Extended Tool Life
-
Advanced Coating Technology: The proprietary TiAlN+ coating reduces friction and dissipates heat, preventing premature wear.
-
Corner Radius Reinforcement: The rounded edges distribute cutting forces evenly, minimizing edge chipping in hardened steels.
3. Versatile Applications
-
Ideal for:
-
Die/mold machining (hardened tool steels)
-
Aerospace components (titanium, Inconel)
-
Automotive forging dies
-
General heavy-duty roughing
-
Recommended Cutting Parameters
| Material | Speed (m/min) | Feed (mm/tooth) | Depth of Cut (axial) | Width of Cut (radial) |
|---|---|---|---|---|
| Hardened Steel (HRC45-56) | 60-90 | 0.08-0.12 | 0.5-1.0xD | 0.3-0.5xD |
| Stainless Steel | 70-100 | 0.10-0.15 | 1.0-1.5xD | 0.4-0.6xD |
| Titanium Alloys | 50-80 | 0.06-0.10 | 0.3-0.8xD | 0.2-0.4xD |
