Chipbreaker Profile
The 8,0 mm drill features a optimized flute profile with a proprietary chipbreaker geometry designed to curl and evacuate chips efficiently, preventing chip packing and reducing cutting forces. The 2-flute design provides wide flute channels for superior chip evacuation even in deep-hole (5xD) applications.
| Feature | Specification |
|---|---|
| Flute Type | Parabolic, 2-flute |
| Chipbreaker Style | Continuous helical groove with polished flanks |
| Flute Surface Finish | Ra 0.2 μm (mirror polish) |
| Chip Form | 6–9 mm C-type / short spiral (steel) |
| Evacuation Efficiency | ≥ 95% at recommended feeds |
Recommended Applications & Workpiece Materials
| Material Group | ISO Code | Machinability | Recommended |
|---|---|---|---|
| Carbon Steel (≤ 0.5% C) | P.1 – P.2 | ★★★★★ | Yes – Excellent |
| Alloy Steel (≤ 900 N/mm²) | P.3 – P.4 | ★★★★☆ | Yes – Very Good |
| Stainless Steel (Austenitic) | M.1 – M.2 | ★★★☆☆ | Yes – Good (reduce Vc 20%) |
| Cast Iron (Gray / Nodular) | K.1 – K.3 | ★★★★☆ | Yes – Very Good |
| Aluminum Alloy (Si ≤ 10%) | N.1 – N.2 | ★★★★★ | Yes – Excellent (uncoated preferred) |
| Hardened Steel (45–55 HRC) | H.1 – H.2 | ★★☆☆☆ | Conditional – Reduce parameters |
| Titanium Alloy | S.1 – S.2 | ★★☆☆☆ | Conditional – Use flood coolant |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Optimal chip evacuation; use peck cycle for >3xD |
| Blind-hole Drilling | ★★★★☆ | Ensure adequate coolant flow; retract to clear chips |
| Stack Drilling | ★★★☆☆ | Clamp workpieces firmly; watch for inter-layer burrs |
| Cross-hole Drilling | ★★★☆☆ | Reduce feed by 30% at intersection point |
| Enlarging / Reaming | ★★☆☆☆ | Not recommended; use dedicated reamer for tolerance |
| Trepanning | ★☆☆☆☆ | Not applicable – solid tool design |
Recommended Cutting Conditions
| Workpiece Material | Vc (m/min) | fn (mm/rev) | Coolant |
|---|---|---|---|
| Low-Carbon Steel (C35) | 88 | 0.2 | Internal / External (8% emulsion) |
| Alloy Steel (42CrMo4) | 73 | 0.17 | Internal / External (8% emulsion) |
| Stainless Steel (316L) | 73 | 0.16 | High-pressure internal (70 bar) |
| Gray Cast Iron (GG25) | 108 | 0.2 | External or dry (compressed air) |
| Aluminum Alloy (AlSi10Mg) | 161 | 0.24 | External (synthetic coolant) |
| Hardened Steel (50 HRC) | 48 | 0.12 | High-pressure internal (70 bar) |
Operating Guidelines
- Peck Cycle: For holes deeper than 3xD, use a peck depth of 1–1.5xD with full retraction to clear chips.
- Coolant Pressure: Maintain minimum 20 bar internal coolant pressure for effective chip evacuation in 5xD applications.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent walk-off on angled surfaces.
- Spindle Warm-up: Run spindle at 50% Vc for 2–3 minutes before full-load operation to stabilize thermal expansion.
- Tool Life Check: Monitor flank wear (VB). Regrind or replace when VB exceeds 0.15 mm for finish holes or 0.25 mm for roughing.
- Storage: Store in original packaging away from humidity and direct sunlight. Avoid contact with other tools to prevent edge damage.
Toolholder Compatibility
| Toolholder Model | Type | Compatibility |
|---|---|---|
| ST32-DR10 | Hydraulic Chuck | Direct fit, shank Ø 8.0 mm |
| HSK63F-DR06 | Shrink Fit | Requires HSK-A63 interface |
| ST20-DR06 | Collet Chuck (ER32) | Use ER32-6 collet for Ø 8.0 mm |
Note: Runout at the tool tip should not exceed 0.01 mm for optimal hole quality and tool life. Always balance toolholder assemblies for high-speed operation (>10,000 rpm).
