4. Grade Details — Key Grade Characteristics
The PR1535 grade is a premium sub-micron carbide substrate engineered for high-speed milling applications. Key characteristics include:
- Substrate: Ultra-fine grain tungsten carbide (0.5–0.8 μm) with 10–12% cobalt binder
- Coating: Multi-layer PVD coating (TiAlN-based) for enhanced heat resistance and reduced friction
- Hardness: HRA 92.5–93.0, providing excellent wear resistance at elevated temperatures
- Transverse Rupture Strength: >3,800 MPa, ensuring robust performance in interrupted cuts
- Oxidation Resistance: Effective up to 900°C (1,652°F)
- Surface Finish: Mirror-polished flute surfaces (Ra < 0.2 μm) for superior chip flow

6. Chipbreaker Profile
The SGM series features a specialized flute geometry optimized for micro-scale chip formation and evacuation:
- Flute Form: Parabolic core with variable helix angle (30° ± 2°) to suppress harmonic vibration
- Core Thickness: 65% of cutting diameter for maximum rigidity in deep-pocket milling
- Rake Angle: Positive 8°–12° rake for reduced cutting forces and improved chip flow
- Clearance Angle: Secondary clearance of 15°–20° to minimize flank wear
- Edge Preparation: Micro-honed cutting edge (radius 0.003–0.005 mm) to prevent chipping
- Chipbreaker: Not applicable (solid endmill); chip control achieved through flute geometry and cutting parameters

9. Recommended Cutting Conditions
Parameters are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing.
| Material | Cutting Speed (SFM) | Feed per Tooth (IPT) | Axial DOC | Radial WOC |
|---|---|---|---|---|
| Carbon Steel (1045) | 300–450 | 0.0005–0.0010 | 1×D1 | 0.5×D1 |
| Stainless Steel (304) | 200–300 | 0.0003–0.0007 | 0.8×D1 | 0.4×D1 |
| Aluminum (6061) | 600–900 | 0.0010–0.0020 | 1.5×D1 | 0.75×D1 |
| Titanium (Ti-6Al-4V) | 80–150 | 0.0002–0.0005 | 0.5×D1 | 0.3×D1 |
| Tool Steel (H13, 30 HRC) | 250–350 | 0.0004–0.0008 | 0.8×D1 | 0.4×D1 |
10. Operating Guidelines
- Coolant: Flood coolant or high-pressure through-spindle coolant (MQL acceptable for aluminum) is strongly recommended to extend tool life and improve surface finish.
- Runout: Maintain total indicated runout (TIR) < 0.0002" (5 μm) at the tool tip. Excessive runout will cause uneven flute wear and premature failure.
- Entry Strategy: Avoid direct plunging. Use helical or ramp entry with a maximum angle of 2°–3°.
- Speeds & Feeds: Start at the lower end of the recommended range and increase gradually while monitoring tool wear and surface finish.
- Tool Life Monitoring: Inspect flutes after each machining cycle for chipping or coating delamination. Replace when flank wear exceeds 0.003" (0.08 mm).
- Storage: Store in original packaging away from moisture and direct sunlight. Avoid contact with hard surfaces that may damage cutting edges.
