Grade Details - Key Grade Characteristics
KW10 — Ultra-fine grain uncoated carbide for non-ferrous materials, delivering mirror finishes and extended edge sharpness.
- Micro-grain carbide substrate (0.5–0.8 μm grain size) for high edge integrity
- Advanced PVD multi-layer coating reduces friction and built-up edge formation
- Optimized cobalt binder content balances hardness and toughness
- Thermal stability up to 900°C cutting temperature
Grade Comparison Matrix
| Grade | Coating | Primary Material | Speed Capability |
| PR1535 | TiAlN PVD | Steel & Alloy Steel | High (80–120 m/min) |
| CA6535 | TiSiN PVD | Stainless Steel | Medium-High (60–100 m/min) |
| PR1725 | TiAlN+CrN | Cast Iron | High (100–140 m/min) |
| KW10 | Uncoated | Aluminum & Non-Ferrous | Very High (150–300 m/min) |
Chipbreaker Profile
The D91 series features a polished flute surface with optimized helix geometry and a specialized margin design that promotes efficient chip evacuation. The thinned web design reduces thrust forces by up to 25% compared to conventional drills, while the polished chip flutes prevent material adhesion—critical for aluminum & non-ferrous applications.
Recommended Applications & Workpiece Materials
Perfect for aluminum alloys, copper, brass, and engineered plastics requiring burr-free holes.
- CNC machining centers and turning centers with through-tool coolant
- High-volume production drilling where tool change intervals impact throughput
- Applications requiring tight hole tolerances (IT8–IT9 achievable)
- Blind and through-hole drilling up to 3×D without pecking
Application Map by Operation
| Operation | Suitability | Conditions |
| Through-Hole Drilling | ✓ Excellent | Standard feed/rev, coolant ON |
| Blind-Hole Drilling | ✓ Excellent | Reduce feed 20% at bottom, coolant ON |
| Stack Drilling | ✓ Good | Use rigid setup, min. 1.5×D clamping |
| Cross-Hole Intersection | △ Moderate | Reduce speed 30% at intersection |
| Inclined Entry | ✓ Good | Spot drill recommended >15° incline |
Recommended Cutting Conditions
| Parameter | Minimum | Recommended | Maximum |
| Cutting Speed (Vc) | 60 m/min | 105 m/min | 150 m/min |
| Spindle Speed (n) | 1768 RPM | 3094 RPM | 4420 RPM |
| Feed per Rev (fn) | 0.135 mm/rev | 0.175 mm/rev | 0.215 mm/rev |
| Depth of Cut (ap) | 1.0×D | 2.0×D | 3.0×D |
| Coolant Pressure | 20 bar | 40 bar | 70 bar |
Operating Guidelines
- Always use high-quality water-miscible coolant or oil with 8–12% concentration
- Ensure tool runout does not exceed 0.02 mm at the tool tip
- For holes deeper than 2.5×D, use peck drilling cycle with 1×D peck depth
- Verify chip evacuation; long chips indicate insufficient feed or coolant
- Replace tool when flank wear (VB) reaches 0.3 mm or when burr formation increases
Toolholder Compatibility
| Holder Type | Compatibility | Notes |
| Hydraulic Chucks (Hydro) | ✓ Excellent | Best damping, recommended for >2×D |
| Shrink Fit Holders | ✓ Excellent | Maximum torque transmission, high-speed safe |
| ER Collets (ER25/ER32) | ✓ Good | Use precision collets; max runout 0.01 mm |
| Side-Lock (Weldon) | ✓ Good | Secure for heavy feeds; check balance rating |
