Grade Details - Key Grade Characteristics
The PR1535 grade utilized in the SGM00779 represents Kyocera's advanced carbide substrate technology optimized for high-speed milling applications:
- Substrate: Ultra-fine grain tungsten carbide (0.5 μm grain size) with 12% cobalt binder
- Coating: AlTiN (Aluminum Titanium Nitride) multi-layer PVD coating, 3.0 μm thickness
- Hardness: HRA 92.5 / HV 1750
- Transverse Rupture Strength: 4,200 MPa
- Oxidation Resistance: Up to 900°C operating temperature
- Friction Coefficient: 0.35 (dry machining against steel)

Chipbreaker Profile
The SGM00779 features an optimized ball nose edge geometry with a proprietary variable helix design that functions as an effective chip management system:
- Edge Preparation: Honned T-land with 0.05 mm x 20° chamfer for edge stability
- Core Thickness: 60% of tool diameter for maximum rigidity in deep pocket milling
- Flute Form: Parabolic flute profile with polished flutes (Ra 0.2 μm) for enhanced chip evacuation
- Variable Helix: 38°/42° alternating helix suppresses chatter in long-overhang applications
- Corner Geometry: Full ball nose radius with micro-polished surface for mirror-finish 3D contouring
Recommended Applications & Workpiece Materials
| Material Group | Specific Grade | Hardness (HRC) | Suitability |

| Stainless Steel (≤HRC25) | AISI 304 / 316L | ≤ 25 | ★★★★☆ |
Application Map by Operation
| Operation Type | Recommended | Max Ae (mm) | Max Ap (mm) |
|---|---|---|---|
| 3D Contouring / Finishing | ✓ Excellent | 0.1D | 1.0D |
| Slot Milling (Full Diameter) | ✓ Good | 1.0D | 1.5D |
| High-Feed Roughing | △ Moderate | 0.3D | 2.0D |
| Plunge Milling | ✓ Good | 0.5D | 0.8D |
| Profile Milling | ✓ Excellent | 0.2D | 1.2D |
Recommended Cutting Conditions
| Parameter | Value | Notes |
|---|---|---|
| Cutting Speed (Vc) | 84.0 m/min | Reduce 20% for stainless steel |
| Feed per Tooth (fz) | 0.0101 mm/z | Increase 15% for roughing |
| Spindle Speed (n) | 23925.0 RPM | Verify machine capability |
| Feed Rate (Vf) | 967.0 mm/min | Calculated: fz × z × n |
| Axial Depth (ap) | 0.022 mm | Max 1.5×D for slotting |
| Radial Depth (ae) | 0.013 mm | 0.1×D for finishing passes |
Operating Guidelines
- Coolant Recommendation: Air blast or mist coolant preferred. If flood coolant is used, ensure adequate concentration (8-10%) to prevent thermal shock.
- Ramping: Maximum ramp angle 2° for full flute engagement. Use helical entry for pocketing operations.
- Tool Overhang: Keep L/D ratio ≤ 4 for optimal stability. Use shrink-fit or hydraulic chucks for ratios exceeding 4.
- Runout Tolerance: Maintain TIR ≤ 0.01 mm at the tool tip to prevent uneven wear and chatter.
- Tool Life Benchmark: Expected flank wear (VB) = 0.15 mm. Replace when wear land reaches 0.2 mm or edge chipping is observed.
- Storage: Store in original packaging at 15-25°C with humidity <60% RH to preserve coating integrity.
Toolholder Compatibility
| Toolholder Type | Shank Fit | Recommended For |
|---|---|---|
| Hydraulic Chuck (Hydro) | H6 | High-precision finishing, L/D > 4 |
| Shrink-Fit Chuck | H6 | High-speed machining, best runout control |
| ER Collet Chuck (ER16/ER20) | H6 | General purpose, versatile clamping |
| Milling Chuck (Power) | H6 | Heavy roughing, high torque transmission |
