Application Map by Operation
| Operation | Suitability | Max Depth | Notes |
|---|---|---|---|
| Through-hole Drilling | ✓✓✓ Optimal | 5×D | Best chip evacuation |
| Blind-hole Drilling | ✓✓✓ Optimal | 3×D | Use peck cycle |
| Stack Drilling | ✓✓ Suitable | 2×D | Clamp plates firmly |
| Cross-hole Drilling | ✓✓ Suitable | 2×D | Reduce feed 30% |
| Interrupted Cut | ✓ Possible | 1.5×D | Reduce speed 20% |
Recommended Cutting Conditions
| Workpiece Material | Vc (sfm) | Vc (m/min) | Feed (ipr) | Feed (mm/rev) |
|---|---|---|---|---|
| Carbon Steel (AISI 1045) | 50-65 | 15.0-20.0 | 0.001-0.0027 | 0.025-0.069 |
| Alloy Steel (AISI 4140) | 40-50 | 12.0-15.0 | 0.0009-0.0023 | 0.023-0.058 |
| Stainless Steel (304) | 33-43 | 10.0-13.0 | 0.0008-0.002 | 0.02-0.051 |
| Cast Iron (GG25) | 64-84 | 20.0-26.0 | 0.001-0.0027 | 0.025-0.069 |
| Aluminum (6061-T6) | 104-144 | 32.0-44.0 | 0.0015-0.0049 | 0.038-0.123 |
Values are starting recommendations. Adjust based on machine rigidity, coolant concentration, and hole depth. Use internal coolant (10-15% emulsion) for optimal performance.
Operating Guidelines
- Coolant: Water-soluble coolant (8-12% concentration) at 6-8 bar pressure. Minimum flow rate 12 L/min for 0.339" tools.
- Peck Cycle: For depths >3×D, use peck depth of 1×D with full retract to break chips.
- Entry Angle: Drill perpendicular to surface (90° ± 2°). For angled entry, use spot drill first.
- Pre-drilling: Not required for 0.339" diameter. For stacked materials, use pilot hole 0.005" smaller.
- Spindle Runout: Maintain TIR ≤ 0.0004" (10 μm) at tool tip for optimal tool life.
- Tool Overhang: Minimize overhang. Use collet chuck or hydraulic chuck for best results.
Toolholder Compatibility
| Holder Type | Clamp Range | Suitability | Runout |
|---|---|---|---|
| ER Collet (ER25/ER32) | 0.344" | ★★★★★ Excellent | ≤5 μm |
| Hydraulic Chuck | 0.344" | ★★★★★ Excellent | ≤3 μm |
| Shrink Fit | 0.344" | ★★★★★ Excellent | ≤2 μm |
| Weldon Side-Lock | 0.344" | ★★★☆☆ Good | ≤15 μm |
