Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ | Ideal for full breakthrough with clean exit |
| Blind-Hole Drilling | ★★★★☆ | Use peck cycle for depths >3×D |
| Chamfering | ★★★☆☆ | Not recommended as primary operation |
| Spot Drilling | ★★★★☆ | Self-centering 140° point geometry |
| Enlarging | ★★★☆☆ | Possible with reduced feed rates |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) | Feed Rate (fn) | Coolant |
|---|---|---|---|
| Carbon Steel | 70 - 110 m/min | 0.12 - 0.22 mm/rev | Emulsion / MQL |
| Stainless Steel | 50 - 80 m/min | 0.10 - 0.18 mm/rev | High-Pressure Coolant |
| Aluminum | 80 - 120 m/min | 0.15 - 0.25 mm/rev | Air / MQL |
| Cast Iron | 60 - 90 m/min | 0.12 - 0.20 mm/rev | Flood Coolant |
Operating Guidelines
- Runout: Maintain spindle runout below 0.01mm for optimal tool life and hole accuracy
- Peck Cycle: For holes deeper than 3×D, use peck depth of 1×D with full retract to break chips
- Coolant: Ensure adequate coolant flow (minimum 6-8 bar) to prevent overheating and chip packing
- Entry Angle: Use rigid fixturing; avoid angled entry greater than 2° without pilot hole
- Speed/Feed: Start at 80% of recommended Vc and fn, then optimize based on chip formation and sound
- Tool Life: Monitor flank wear; regrind or replace when wear land exceeds 0.3mm
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck (Hydro) | ★★★★★ | Best damping; recommended for deep holes |
| Shrink Fit | ★★★★★ | Excellent rigidity and runout control |
| ER Collet (ER16-ER32) | ★★★★☆ | Use high-precision collets (AA grade) |
| Weldon Shank | ★★★☆☆ | Acceptable for shallow holes only |
