| Full MPN | SGS56250 | Manufacturer Part Number for exact ordering |
Engineering Dimensions & Geometry
| Parameter | Value | Tolerance |
|---|---|---|
| Drill Diameter (D) | 9.5 mm | h5 (±0.004 mm) |
| Overall Length (L) | 120 mm | ±0.5 mm |
| Flute Length (Lf) | 50 mm | ±0.3 mm |
| Helix Angle | 35° | ±2° |

Grade Details - Key Grade Characteristics
- Substrate Composition: Ultra-fine grain carbide (0.5 μm grain size) with 12% cobalt binder for optimal hardness-toughness balance
- Coating Technology: Multi-layer DLC PVD coating (3.0 μm thickness) providing oxidation resistance up to 900°C
- Hardness: HRC 45-55 workpiece material compatibility with 92.5 HRA substrate hardness
- Surface Finish: Mirror-polished flute surfaces (Ra 0.1 μm) minimize friction and built-up edge formation
- Edge Preparation: Honing radius 0.02-0.03 mm for micro-chipping resistance without compromising sharpness
Grade Comparison Matrix
| Property | Grade TA | Standard Grade | Performance Gain |
|---|---|---|---|
| Wear Resistance | ★★★★★ | ★★★☆☆ | +40% |
| Heat Resistance | ★★★★★ | ★★★☆☆ | +35% |
| Chip Control | ★★★★☆ | ★★★☆☆ | +25% |
| Surface Finish Quality | ★★★★★ | ★★★★☆ | +20% |
| Toughness / Chipping Resistance | ★★★★☆ | ★★★☆☆ | +30% |
Chipbreaker Profile
The #41 TA drill features an optimized flute geometry that functions as an integrated chipbreaker system. The 35° helix angle combined with a variable core thickness (0.35D to 0.45D) creates natural chip segmentation without dedicated insert-style breakers. Key profile characteristics include:
- Variable flute width ratio (1.2:1) promoting controlled chip curling
- Polished rake face (γ = 12°) reducing cutting forces by 15% compared to conventional designs
- Secondary relief angle (8°) preventing flank rubbing in deep-hole applications
- Internal coolant channels (where applicable) for enhanced chip flushing in blind-hole operations
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended Use |
|---|---|---|
| Hastelloy | ★★★★★ | Primary target material; optimized cutting geometry |
| Carbon & Alloy Steels | ★★★★☆ | Excellent performance with standard parameters |
| Stainless Steels (AISI 300/400) | ★★★★☆ | Reduced speed recommended; superior finish quality |
| Cast Iron (Gray/Ductile) | ★★★★☆ | Dry machining capable; extended tool life |
| Aluminum Alloys | ★★★☆☆ | Use uncoated alternative for best results |
| Hardened Steels (HRC 45-55) | ★★★★☆ | Specialist application; reduced feed rates |
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ✓ Excellent | Standard application; full parameter range |
| Blind-Hole Drilling | ✓ Excellent | Reduce feed by 20% in final 1D depth |
| Stack Drilling | ✓ Good | Ensure proper clamping; peck cycle recommended |
| Cross-Hole Drilling | △ Moderate | Reduce speed 15%; rigid setup required |
| Enlarging / Reaming | ✗ Not Recommended | Use dedicated reamer for precision sizing |
| Trepanning / Core Drilling | △ Limited | Not designed for interrupted cuts |
Recommended Cutting Conditions
| Parameter | Range | Optimal Setting |
|---|---|---|
| Cutting Speed (Vc) | 125-185 m/min | Mid-range for balanced tool life |
| Feed per Revolution (f) | 0.12-0.21 mm/rev | 0.12 mm/rev for Hastelloy |
| Depth of Cut (Ap) | 1.3-1.9D | 2.0D for through-hole |
| Coolant Concentration | 6-8% emulsion | 7% for general purpose |
| Coolant Pressure | 20-70 bar | 40+ bar for deep holes (>3D) |
| Spindle Speed (n) | Calculated from Vc | n = (Vc × 1000) / (π × D) |
Operating Guidelines
- Run-in Procedure: For first 5 minutes, operate at 70% recommended cutting speed to allow coating adaptation
- Peck Cycle: Use G73 (high-speed peck) or G83 (deep hole peck) for holes deeper than 2.5D; retract to clear chips every 0.5D
- Entry Angle: Ensure perpendicular entry (±0.5°) to prevent corner chipping; use spotting drill for inclined surfaces
- Tool Overhang: Minimize overhang to 3D or less; use hydraulic or shrink-fit holders for maximum rigidity
- Wear Monitoring: Replace tool when flank wear (VB) reaches 0.15 mm or when burr formation exceeds 0.05 mm
- Storage: Store in original packaging at 15-25°C with <60% relative humidity to prevent corrosion
Toolholder Compatibility
| Holder Type | Compatibility | Recommended Torque |
|---|---|---|
| Hydraulic Chuck (HSK-A63) | ✓ Preferred | System-dependent; auto-clamp |
