| N - Non-Ferrous | Aluminum 6061, Brass, Copper | ★★★☆☆ Good |
| S - Super Alloys | Inconel 718, Titanium Ti-6Al-4V | ★★★☆☆ Good (reduced speed) |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Primary application, optimized chip evacuation |
| Blind-Hole Drilling | ★★★★☆ | Use peck cycle for depths >5D |
| Spot Drilling | ★★★★☆ | 135° point matches standard chamfers |
| Counterboring | ★★★☆☆ | Possible with reduced feed |
| Enlarging | ★★★☆☆ | Use pilot hole for best results |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) SFM | Feed (fn) IPR | Coolant |
|---|---|---|---|
| Carbon Steel (< 30 HRC) | 120-150 | 0.05-0.08 | Emulsion / Synthetic |
| Alloy Steel (30-45 HRC) | 96-120 | 0.05-0.08 | Emulsion / Synthetic |
| Stainless Steel (AISI 304) | 80-100 | 0.04-0.06 | High-Pressure External |
| Cast Iron (GG/GGG) | 132-165 | 0.06-0.096 | Compressed Air / Mist |
| Aluminum (Al 6061) | 300-400 | 0.12-0.20 | Air / Mist |
Operating Guidelines
- Coolant Supply: Maintain external coolant flow rate of 15-20 L/min directed at the cutting point.
- Peck Cycle: For holes deeper than 5D, use a peck depth of 1-1.5D with full retract to break chips.
- Rigidity: Ensure minimal tool overhang. Use hydraulic or shrink-fit holders for best results.
- Entry Angle: Drill perpendicular to surface. If angled entry is required, use a spot drill first.
- Speed/Feed: Start at the lower end of the recommended range and increase gradually based on chip formation and tool wear.
- Tool Life: Monitor flank wear. Regrind or replace when wear land exceeds 0.3 mm.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic Chuck | ★★★★★ | Best for high-precision and high-speed |
| Shrink Fit Holder | ★★★★★ | Maximum rigidity and runout control |
| Milling Chuck | ★★★★☆ | Good for general-purpose applications |
| ER Collet Chuck | ★★★☆☆ | Acceptable for lower speeds; ensure high-quality collet |
| Drill Chuck | ★★☆☆☆ | Not recommended for high-precision CNC |
