- Web Thinning: Advanced web-thinning point geometry for reduced thrust forces
- Edge Preparation: Honing (T-land) for edge stability and chipping resistance
Recommended Applications & Workpiece Materials
| Material Group | Machinability | Recommended |
|---|---|---|
| Carbon Steel (P1 – P3) | ★★★★★ | Excellent |
| Alloy Steel (P4 – P6) | ★★★★☆ | Very Good |
| Stainless Steel (M1 – M2) | ★★★★☆ | Very Good |
| Cast Iron (K1 – K3) | ★★★★★ | Excellent |
| Aluminum (N1 – N3) | ★★★☆☆ | Good (with adjusted parameters) |
| Titanium Alloys (S1 – S2) | ★★★☆☆ | Good (reduced speeds) |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Primary application; optimized chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Ensure adequate peck cycle for chip clearance |
| Stack Drilling | ★★★☆☆ | Use reduced feed to prevent burr formation |
| Micro-Hole Drilling | ★★★★☆ | High spindle speeds required |
| Enlarging / Reaming | ★★☆☆☆ | Not recommended; use dedicated reamer |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed (f) |
|---|---|---|
| Carbon Steel | 80 – 120 m/min | 0.10 – 0.18 mm/rev |
| Alloy Steel | 60 – 90 m/min | 0.08 – 0.15 mm/rev |
| Stainless Steel | 50 – 70 m/min | 0.08 – 0.12 mm/rev |
| Cast Iron | 100 – 140 m/min | 0.12 – 0.20 mm/rev |
| Aluminum | 150 – 250 m/min | 0.15 – 0.25 mm/rev |
| Titanium Alloy | 30 – 50 m/min | 0.06 – 0.10 mm/rev |
Operating Guidelines
- Coolant: High-pressure internal coolant (70+ bar) is strongly recommended for chip evacuation and heat dissipation
- Peck Cycle: For holes deeper than 3×D, use a peck depth of 1–1.5×D to prevent chip packing
- Spindle Runout: Maintain TIR < 0.01 mm at the tool tip for optimal hole quality and tool life
- Tool Overhang: Minimize overhang to reduce vibration; use hydraulic or shrink-fit holders where possible
- Entry Angle: Ensure perpendicular entry or use a spot drill to prevent walking and chipping
- Speed/Feed Ramp: Reduce feed by 50% for the first 1 mm of engagement to stabilize the drill
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best damping; recommended for deep holes |
| Shrink-Fit Holder | ★★★★★ | Excellent runout and torque transmission |
| ER Collet Chuck | ★★★★☆ | Use high-precision collets (ER16-UP / ER20-UP) |
| Milling Chuck | ★★★☆☆ | Acceptable for shallow holes; verify runout |
| Drill Chuck | ★★☆☆☆ | Not recommended for high-precision CNC work |
