Chipbreaker Profile
High-polish positive rake chipbreaker with large flute volume designed for uninterrupted chip flow and elimination of built-up edge in aluminum machining.
- Optimized flute profile ensures continuous chip formation and evacuation
- Polished rake surface minimizes friction and built-up edge formation
- Reinforced cutting edge corner improves edge stability in interrupted cuts
- Variable helix design reduces harmonic vibration and chatter
Recommended Applications & Workpiece Materials
The SGS51508 with TA grade is specifically engineered for machining the following material groups:
Aluminum alloys (6061-T6, 7075-T6), copper, brass, bronze, magnesium alloys, plastics, and composite materials.
Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimal chip evacuation with 2-flute design |
| Blind-Hole Drilling | ★★★★☆ Very Good | Ensure adequate peck cycle for chip clearance |
| Stack Drilling | ★★★★☆ Very Good | Use reduced feed at interface transitions |
| Cross-Hole Drilling | ★★★☆☆ Good | Reduce speed by 20% at intersection points |
| Enlarging / Reaming | ★★☆☆☆ Fair | Not recommended; use dedicated reamer for finishing |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Revolution fn (mm/rev) |
|---|---|---|
| Aluminum 6061 | 200-350 | 0.10-0.20 |
| Aluminum 7075 | 180-300 | 0.08-0.18 |
| Copper / Brass | 150-250 | 0.10-0.20 |
| Plastics | 100-200 | 0.05-0.15 |
Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece fixturing. Use high-pressure coolant (70+ bar) for deep-hole applications.
Operating Guidelines
- Coolant: High-pressure soluble oil or synthetic coolant (8-12% concentration) recommended. Minimum 20 bar pressure for 5XD applications.
- Peck Cycle: For 5XD drills, use full retraction peck cycle every 1.045" or when chip load exceeds 1.5× flute diameter.
- Entry Angle: Ensure perpendicular entry (±1°) or use spot drill / chamfer to prevent walk.
- Pre-Spotting: Recommended for #4 diameter and above to improve positional accuracy.
- Tool Overhang: Minimize overhang to 3× diameter or less for optimal stability and hole straightness.
- Spindle Runout: Maintain TIR ≤ 0.01 mm at tool tip for best performance and tool life.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic Chuck | ★★★★★ Excellent | Best damping; ideal for 5XD deep-hole drilling |
| Shrink Fit | ★★★★★ Excellent | Maximum torque transmission and runout accuracy |
| ER Collet (ER25-ER40) | ★★★★☆ Very Good | Use precision collet (≤5 μm runout) for best results |
| Weldon Flat | ★★★☆☆ Good | Acceptable for short-hole applications only |
