8. Application Map by Operation
| Operation Type | Description | Compatibility | Notes |
|---|---|---|---|
| Through-Hole Drilling | Drilling completely through the workpiece | ✓ Ideal | Standard application; use peck cycle for L/D > 3 |
| Blind Hole Drilling | Drilling to a specified depth without breakthrough | ✓ Ideal | Precise depth control; reduce feed by 20% at bottom |
| Stack Drilling | Drilling through multiple clamped plates | ✓ Suitable | Ensure plate alignment; use pilot hole if gap > 0.5 mm |
| Inclined Entry | Drilling at angle or into curved surface | △ Caution | Reduce speed 30%; use center drill first for angles > 5° |
| Cross-Hole Drilling | Drilling intersecting an existing hole | △ Caution | Reduce feed 40% at intersection; rigid workholding essential |
| Enlarging / Reaming | Enlarging pre-drilled hole to final size | ✗ Not Recommended | Use dedicated reamer for precision finishing |
9. Recommended Cutting Conditions
The following parameters serve as starting points for stable machining. Adjust based on machine rigidity, coolant delivery, and workpiece material condition.
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Approx. RPM |
|---|---|---|---|
| Carbon Steel (C45) | 120 – 140 | 0.18 – 0.25 | 4063 – 4740 |
| Alloy Steel (42CrMo4) | 90 – 110 | 0.15 – 0.22 | 3047 – 3724 |
| Stainless Steel (304) | 60 – 80 | 0.12 – 0.18 | 2031 – 2709 |
| Cast Iron (GG25) | 100 – 120 | 0.15 – 0.22 | 3386 – 4063 |
| Aluminum (7075) | 200 – 250 | 0.25 – 0.35 | 6772 – 8465 |
| Hardened Steel (50 HRC) | 40 – 60 | 0.08 – 0.12 | 1354 – 2031 |
Note: RPM values are calculated for the nominal diameter of 9.4 mm. Always verify spindle capability and machine stability before running at maximum parameters. Use internal coolant (15–20 bar) for optimal chip evacuation and tool life.
10. Operating Guidelines
- Coolant: Use high-pressure internal coolant (minimum 15 bar) directed through the tool center. For external coolant, increase flow rate to 8–10 L/min and reduce cutting speed by 15%.
- Peck Cycle: For 3XD drills, implement a peck cycle with retract depth of 0.5–1.0 mm to break chips and allow coolant penetration. First peck depth should not exceed 1.5×D.
- Rigidity: Ensure workpiece clamping and tool overhang are optimized. Minimize overhang to 3×D or less. Use hydraulic or shrink-fit holders for maximum runout control.
- Entry Surface: Drill perpendicular to the surface whenever possible. For inclined or curved entry, use a center drill or spot drill to create a 90° starting surface.
- Feed Rate: Maintain consistent feed. Avoid dwell at the bottom of blind holes. Retract at 2× the drilling feed rate to prevent chip recutting.
- Tool Life Monitoring: Monitor flank wear (VB). Resharpen or replace when VB reaches 0.3 mm or when burr formation increases significantly at hole exit.
- Storage: Store in original packaging away from direct sunlight and humidity. Avoid contact between cutting edges during transport.
11. Toolholder Compatibility
The 9.4 mm shank diameter of the SGS67664 is precision-ground to h6 tolerance, ensuring compatibility with a wide range of standard toolholding systems. The following holder types are recommended for optimal performance:
| Holder Type | Recommended Standard | Max Runout | Application Notes |
|---|---|---|---|
| Hydraulic Chuck | HDC / HPC | ≤0.003 mm | Best for high-speed, precision drilling |
| Shrink Fit | HSK-A63 / HSK-A100 | ≤0.005 mm | Excellent torque transmission, rigid setup |
| Collet Chuck | ER20 / ER25 / ER32 | ≤0.010 mm | Versatile; ensure collet condition is good |
| Weldon Side Lock | DIN 1835-B | ≤0.015 mm | Suitable for heavy-duty, lower-speed applications |
