| Coating | AlTiN (Aluminum Titanium Nitride) PVD | Oxidation resistance up to 900°C; reduced built-up edge |
| Hardness | 92.0 HRA / 1600 HV | Maintains edge integrity at elevated cutting temperatures |
| TRS (Transverse Rupture Strength) | ≥ 4,000 N/mm² | Withstands intermittent cutting and high feed rates |
| Coating Thickness | 2.5 – 3.5 μm | Optimal balance between wear resistance and edge sharpness |
| Coating Color | Dark Gray / Black | Visual identification of coated cutting edge |
Grade Comparison Matrix
| Grade | Coating | Primary Materials | Max Hardness | Wear Resistance |
|---|---|---|---|---|
| PR1535 | AlTiN PVD | Steel, Stainless, Cast Iron | Up to 50 HRC | High |

Chipbreaker Profile
As a solid carbide endmill, the SGM01368 features an engineered 3-flute helical ball nose geometry optimized for 3D surface machining and complex contouring operations.
The SGM01368 features an engineered 3-flute helical ball nose geometry optimized for 3D surface machining and complex contouring operations. The spherical cutting profile is precision-ground to maintain consistent surface finish across varying engagement angles.- Ball Radius Accuracy: Spherical profile tolerance within ±0.0010" (±25 μm) ensuring seamless surface transitions in multi-axis toolpaths.
- Rake Angle: Positive 6° axial rake combined with 3° radial rake for smooth shearing action and reduced scallop height on steep walls.
- Core Thickness: Approximately 55% of cutting diameter, optimized for the combination of rigidity and flute space needed for 3D chip evacuation.
- Edge Preparation: Controlled micro-honing (T-land width 0.015–0.030 mm) protects the spherical cutting edge from premature chipping while maintaining sharpness for fine surface finishes.
- Chip Evacuation: Wide flute gullets with polished surfaces (Ra < 0.2 μm) ensure unimpeded chip flow, critical in high-feed 3D contouring and rest-machining operations.
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Examples | Suitability |
|---|---|---|---|
| Carbon Steel & Alloy Steel | P1 – P5 | 1045, 4140, 4340, A2, D2 | ★★★★★ Excellent |
| Stainless Steel (Austenitic) | M1 – M2 | 304, 316, 321 | ★★★★☆ Very Good |
| Stainless Steel (Martensitic) | M3 | 410, 420, 17-4PH | ★★★★☆ Very Good |
| Cast Iron | K1 – K3 | Gray Iron, Ductile Iron, Malleable Iron | ★★★★☆ Very Good |
| Hardened Steel | H1 – H2 | H13, H11, 4340 @ 45-50 HRC | ★★★☆☆ Good |
| Titanium Alloys | S1 – S2 | Ti-6Al-4V, Ti-5Al-5V | ★★★☆☆ Good (Reduced Speed) |
Application Map by Operation
| Operation | Rating | Recommended Parameters |
|---|---|---|
| 3D Contouring | Excellent | Stepover 0.05–0.15×Dc for fine finish |
| Surface Finishing | Excellent | Mirror-finish capability on hardened steels |
| Semi-Finishing | Very Good | Stepover 0.20–0.30×Dc for stock removal |
| Rest Machining | Excellent | Ideal for corner picking and tight radii |
| Engraving / Texturing | Good | Shallow depth, high spindle speed |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Axial Depth ap (mm) | Coolant |
|---|---|---|---|---|
| Carbon Steel (P) | 50-70 | 0.002-0.006 | 1.0–1.5 × Dc | Emulsion / Air |
| Stainless Steel (M) | 35-50 | 0.002-0.005 | 0.8–1.2 × Dc | Emulsion (High Pressure) |
| Cast Iron (K) | 70-90 | 0.003-0.008 | 1.2–2.0 × Dc | Air / MQL |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece clamping, and surface finish requirements. For hardened steels (>45 HRC), reduce Vc by 20–30% and use lower feed rates. For ball nose tools, use stepover (ae) of 0.05–0.15×Dc for finishing and 0.20–0.30×Dc for semi-finishing.
Operating Guidelines
- Runout Control: Maintain total indicated runout (TIR) below 5 μm at the tool tip. Excessive runout dramatically reduces tool life in micro-diameter tools. Use shrink-fit or high-precision collet holders.
- Tool Overhang: Minimize overhang to the shortest length required for the feature. Rule of thumb: overhang ≤ 4× tool diameter for stable cutting. For deep cavities, consider stepped or necked tools.
- Coolant Strategy: High-pressure coolant (70+ bar) directed at the cutting zone is recommended for stainless steel and deep-pocket applications. For cast iron and some steels, air blast or MQL is sufficient and prevents thermal cracking.
- Entry Strategy: Avoid direct plunging into solid material. Use helical interpolation or ramping entry with a maximum ramp angle of 2°–3° to prevent corner chipping. For ball nose tools, use tangential entry along the workpiece surface to minimize impact on the spherical tip.
- Chip Evacuation: Ensure adequate chip evacuation, especially in blind pockets and slots. Recutting chips is the primary cause of premature failure in micro endmills.
- Speed/Feed Ramp-Up: When testing new parameters, start at 70% of recommended cutting speed and increase incrementally while monitoring spindle load and surface finish.
Toolholder Compatibility
| Holder Type | Clamping Range | Recommendation |
|---|---|---|
| ER11 Collet Chuck | 0.125" (3.175 mm) | Recommended for micro tools |
| ER16 Collet Chuck | 0.125" (3.175 mm) | High rigidity option |
| Shrink Fit Holder | 0.125" (3.175 mm) | Best runout control (<3 μm) |
| Hydraulic Chuck | 0.125" (3.175 mm) | Damping for unstable setups |
Minimum Clamping Length: Ensure at least 2.5× shank diameter (≥ 8 mm) is gripped inside the holder to prevent pull-out and maintain rigidity.
