Application Map by Operation
| Operation | Suitability | Recommended Vc | Notes |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | 100% Standard Vc | Primary application; use peck cycle for L/D > 3 |
| Blind-Hole Drilling | ★★★★☆ Very Good | 90% Standard Vc | Reduce feed by 20% in last 1 mm to control burr |
| Spot Drilling / Centering | ★★★★☆ Very Good | 80% Standard Vc | Self-centering point eliminates separate spotting |
| Chamfering | ★★★☆☆ Good | 60% Standard Vc | Light chamfering only; max 0.3 mm depth |
| Countersinking | ★★☆☆☆ Fair | 50% Standard Vc | Not recommended; use dedicated countersink |
Recommended Cutting Conditions
Parameters optimized for 3.70 mm diameter. Adjust based on machine rigidity and workpiece material condition.
| Workpiece Material | Cutting Speed Vc (m/min) | Spindle Speed n (rpm) | Feed f (mm/rev) | Coolant Strategy |
|---|---|---|---|---|
| Carbon Steel (<30 HRC) | 100 – 120 | 8,602 | 0.094 | External / Through-tool |
| Alloy Steel (30-45 HRC) | 80 – 100 | 7,741 | 0.080 | High-Pressure Internal |
| Stainless Steel (Austenitic) | 60 – 80 | 6,022 | 0.071 | High-Pressure (15-20 bar) |
| Gray / Ductile Cast Iron | 90 – 110 | 8,602 | 0.118 | External / Dry |
Operating Guidelines
- Runout Control: Maintain tool runout ≤ 0.01 mm at the tool tip. Excessive runout reduces tool life and hole quality.
- Peck Drilling: For hole depths exceeding 3×D, implement a peck cycle with 1×D to 1.5×D peck depth and full retract to break chips.
- Coolant Pressure: When using internal coolant, ensure minimum pressure of 10 bar (20 bar optimal) for effective chip evacuation.
- Entry Angle: Use a rigid setup with minimal overhang. Drill entry surface should be flat and perpendicular to the spindle axis.
- Pre-drilling: For diameters > 5 mm or inclined entries, spot drill first or use a guide bushing to prevent deflection.
- Speed & Feed Ramp: Reduce cutting speed by 15% for the first 10 holes to allow the tool to "warm up" and achieve stable wear patterns.
Toolholder Compatibility
| Holder Type | Compatible Chuck / Collet | Clamping Force | Runout Accuracy | Recommendation |
|---|---|---|---|---|
| Spring Collet Chuck | ER16, ER20, ER25 (≥ 4.0 mm) | Medium | ≤ 0.010 mm | Standard application |
| Hydraulic Chuck | HydroClamp 4.0 mm | High | ≤ 0.003 mm | High-precision finishing |
| Shrink Fit Holder | ThermoGrip 4.0 mm | Very High | ≤ 0.002 mm | Best for high-speed / tight tolerance |
| Weldon Side-Lock | Weldon 4.0 mm (flat required) | High | ≤ 0.015 mm | Heavy-duty roughing only |
