Chipbreaker Profile
The 11/32 features Kyocera's proprietary SGS (Special Groove System) chipbreaker geometry optimized for 2-flute drills. The polished flute surface (Ra 0.2 μm) minimizes built-up edge, while the widened flute gullet provides efficient chip evacuation for 8.73 mm diameter holes up to 5×D depth.
- Polished rake face reduces cutting forces by ~15% compared to standard ground drills
- Enhanced chip curling radius prevents chip packing in deep-hole applications
- Stable chip formation across feed rates of 0.10–0.25 mm/rev
Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability |
|---|---|---|
| Carbon Steel | C45, C60, 1045, 1060 | Excellent |
| Alloy Steel | 4140, 4340, 42CrMo4 | Excellent |
| Stainless Steel | 304, 316, 17-4PH | Very Good |
| Cast Iron | GG25, GGG40, Class 40 | Good |
| Tool Steel | H13, D2, O1 (pre-hardened < 45 HRC) | Good |
| Titanium Alloy | Ti-6Al-4V (limited speed) | Moderate |
Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-hole Drilling | ★★★★★ | Primary application; optimized for full breakthrough |
| Blind-hole Drilling | ★★★★☆ | Use peck cycle for depths > 3×D |
| Cross-hole Drilling | ★★★☆☆ | Reduce feed to 70% at intersection |
| Stack Drilling | ★★★★☆ | Ensure rigid clamping; use coolant |
| Enlarging / Reaming | ★★☆☆☆ | Not recommended; use dedicated reamer |
Recommended Cutting Conditions
| Material | Cutting Speed (Vc) m/min | Feed (f) mm/rev | RPM (approx.) |
|---|---|---|---|
| Mild Steel (< 300 HB) | 80–120 | 0.12–0.20 | 4,009 |
| Alloy Steel (300–400 HB) | 60–90 | 0.10–0.16 | 2,978 |
| Stainless Steel (AISI 304) | 50–70 | 0.10–0.14 | 2,290 |
| Cast Iron (GG25) | 90–130 | 0.14–0.22 | 4,352 |
| Tool Steel (40–45 HRC) | 40–60 | 0.08–0.12 | 1,947 |
Conditions based on high-pressure internal coolant supply (70 bar min) and stable toolholder setup. Adjust by ±15% for dry machining.
Operating Guidelines
- Coolant: High-pressure internal coolant (70–150 bar) strongly recommended for 5×D drilling to ensure chip evacuation and heat dissipation.
- Peck Cycle: For blind holes > 3×D, use peck depth of 1.0–1.5×D with full retract to break chips.
- Tool Overhang: Minimize overhang to < 4×D for best rigidity. Use hydraulic or shrink-fit holders for critical applications.
- Entry Angle: Ensure perpendicular entry (±1°) or use a spot drill to prevent walk-off on angled surfaces.
- Speed/Feed Ramp: Reduce feed by 50% for the first 1 mm of engagement, then ramp to full feed over 0.5 mm.
- Re-sharpening: Not recommended; solid carbide design is intended for full tool life consumption. Inspect for flank wear > 0.3 mm as replacement criterion.
Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| Hydraulic Chuck (Hydro) | ★★★★★ | Best damping; ideal for 5×D applications |
| Shrink Fit | ★★★★★ | Maximum rigidity and runout control (< 3 μm) |
| ER Collet (ER16–ER25) | ★★★★☆ | Acceptable for through-holes; ensure collet quality |
| Milling Chuck | ★★★☆☆ | Use only for short holes (< 2×D) |
| Drill Chuck (Keyless) | ★★☆☆☆ | Not recommended for precision CNC work |
