Grade Details – Key Grade Characteristics
The TA Grade is a sub-micron grain carbide substrate (grain size: 0.5 μm) combined with a multi-layer PVD coating optimized for high-speed milling operations. Key characteristics include:
- Hardness: 92.5 HRA (1,600 HV30) – Exceptional wear resistance in continuous cutting
- Transverse Rupture Strength: 3,800 MPa – High edge stability under intermittent cuts
- Coating Composition: TiAlN-based multi-layer PVD coating with enhanced oxidation resistance up to 900°C
- Coating Thickness: 2.5 μm – Optimal balance between protection and edge sharpness
- Friction Coefficient: 0.35 – Reduced built-up edge and improved chip evacuation
- Thermal Conductivity: 60 W/m·K – Efficient heat dissipation from the cutting zone
Grade Comparison Matrix
| Grade | Hardness (HRA) | TRS (MPa) | Best For | Max Temp |
|---|---|---|---|---|
| TA | 92.5 | 3,800 | Steel, Stainless, General Purpose | 900°C |
| TB | 93.0 | 3,500 | Hardened Steel (>50 HRC) | 950°C |

| TD | 92.0 | 3,900 | Cast Iron, Aluminum | 880°C |
Chipbreaker Profile
The SGM08738 features a precision-ground flute geometry optimized for 2FL flute endmills. The chipbreaker design ensures controlled chip formation and evacuation across a wide range of cutting parameters:
- Flute Profile: Variable helix with 35° primary helix angle minimizes harmonic vibration
- Core Design: Reinforced core (60% of cutter diameter) provides maximum rigidity for reduced deflection
- Edge Preparation: Micro-honed cutting edge (0.02 mm hone) enhances edge stability and prevents chipping
- Corner Geometry: 0.020R radius with polished transition zones reduces stress concentration and extends corner life
- Flute Polishing: Mirror-finished flute surfaces (Ra 0.1 μm) prevent material adhesion and improve chip flow

Operating Guidelines
- Runout Check: Ensure tool runout does not exceed 0.005 mm (0.0002″) at the tool tip. Excessive runout accelerates corner wear and reduces surface finish quality.
- Coolant Strategy: Flood coolant or high-pressure through-spindle coolant (MQL) is recommended for steel and stainless steel. For aluminum, air blast or minimal lubrication prevents built-up edge.
- Ramp Entry: Use helical ramp entry with a maximum ramp angle of 2° for pocketing operations. Avoid plunging directly into solid material.
- Stepover Recommendation: For finishing operations, maintain stepover (ae) between 5-15% of cutter diameter to achieve mirror surface finishes (Ra 0.4 μm or better).
- Chip Load Verification: Always verify actual chip load against calculated values. Insufficient chip load causes rubbing and premature coating failure; excessive chip load leads to chipping.
- Tool Life Indicator: Monitor flank wear (VB). Replace tool when VB exceeds 0.1 mm for roughing or 0.05 mm for finishing operations.

| Shrink Fit | ★★★★☆ | HSK-E32 / HSK-E40 | 50,000 | Excellent runout control (<0.003 mm) |
| Collet Chuck (ER16/ER20) | ★★★☆☆ | BT30 / BT40 | 30,000 | Ensure precision collet (AA grade) |
| Milling Chuck | ★★★☆☆ | BT40 / BT50 | 25,000 | Suitable for heavier roughing cuts |
