Recommended Applications & Workpiece Materials
This tool is optimized for Titanium & High-Temp Alloys. The TA grade substrate and advanced coating provide balanced performance across the following material groups:
- Carbon steels (C35, C45, C60)
- Alloy steels (42CrMo4, 34CrNiMo6, 16MnCr5)
- Tool steels up to 45 HRC (H13, D2, O1)
- Cast iron (GG25, GGG40, GGG50)
- Stainless steels (304, 316, 17-4PH) — moderate speeds
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Primary application; optimized chip evacuation |
| Blind-Hole Drilling | ★★★★☆ Very Good | Ensure adequate peck cycle for chip clearance |
| Stack Drilling | ★★★☆☆ Good | Use reduced feed; clamp plates firmly |
| Cross-Hole Drilling | ★★★☆☆ Good | Reduce speed by 20% at intersection |
| Enlarging / Reaming | ★★☆☆☆ Fair | Not recommended; use dedicated reamer |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed f (mm/rev) |
|---|---|---|
| Carbon Steel (≤ 300 HB) | 82-122 | 0.15-0.26 |
| Stainless Steel (≤ 280 HB) | 52-82 | 0.10-0.18 |
| Aluminum & Alloys | 155-205 | 0.21-0.36 |
| Cast Iron (≤ 250 HB) | 72-112 | 0.15-0.26 |
| Tool Steel (≤ 45 HRC) | 62-102 | 0.15-0.23 |
Note: Start at the lower end of the range and increase based on machine rigidity, coolant delivery, and hole depth-to-diameter ratio. For holes deeper than 3×D, reduce Vc by 15% and use a peck cycle.
Operating Guidelines
- Coolant: High-pressure internal coolant (70–100 bar) is strongly recommended for holes > 2×D. Use water-soluble coolant with 8–10% concentration.
- Peck Cycle: For 3×D–5×D: peck at 1.5×D increments. For > 5×D: peck at 1.0×D increments with full retract.
- Entry Angle: Ensure perpendicular entry (±0.5°) or use a spot drill / chamfer to prevent walk.
- Speed/Feed Ramp: Ramp to full speed over 2–3 seconds; do not plunge at full RPM.
- Tool Life Check: Monitor flank wear (VB). Regrind or replace when VB = 0.15–0.20 mm for steel, 0.10–0.15 mm for stainless.
- Chip Inspection: Chips should be small, curled, and consistent. Long stringers indicate feed is too low or speed is too high.
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| Hydraulic Chuck (HSK-A63) | ★★★★★ Excellent | Best damping; recommended for high-precision work |
| Shrink Fit Chuck | ★★★★★ Excellent | Maximum torque transmission; balanced for high RPM |
| Precision Collet (ER25, ER32) | ★★★★☆ Very Good | Ensure collet is < 0.005 mm runout |
| Milling Chuck | ★★★☆☆ Good | Acceptable for short holes; check clamping force |
| Drill Chuck (Keyless) | ★★☆☆☆ Fair | Not recommended for production; use only for manual setups |
