► Grade Details — Key Grade Characteristics
The D91 series utilizes Kyocera's proprietary micro-grain carbide substrate combined with an advanced PVD TiCN multi-layer coating system. This synergistic combination delivers:
- Ultra-fine grain structure (0.5 μm) for superior edge sharpness and toughness
- PVD TiCN coating providing exceptional thermal stability up to 900°C
- High hardness (HRA 92.5) ensuring minimal wear in high-speed applications
- Optimized cobalt binder (8%) balancing hardness with fracture resistance
- Low friction coefficient reducing built-up edge and improving chip evacuation
► Grade Comparison Matrix
| Property | D91 1450 | Standard Grade | Competitor A |
|---|---|---|---|
| Hardness (HRA) | 92.5 | 91.0 | 91.5 |
| Transverse Rupture (MPa) | 3,800 | 3,200 | 3,400 |

| Tool Life Index | 100% | 75% | 82% |
► Chipbreaker Profile
The D91 1450 features an optimized chipbreaker geometry specifically engineered for Ø14.5 mm drilling operations. The flute profile incorporates a variable helix design with polished rake surfaces to ensure smooth chip formation and evacuation. The proprietary edge preparation minimizes burr formation and reduces cutting forces by up to 15% compared to conventional geometries.
| Geometric Feature | Value | Function |
|---|---|---|
| Rake Angle (γ) | 12°–15° | Reduces cutting force, improves chip flow |
| Relief Angle (α) | 8°–10° | Minimizes flank wear, prevents rubbing |
| Edge Preparation | T-land + hone | Enhances edge stability, prevents chipping |
| Flute Polishing | Ra 0.2 μm | Reduces chip adhesion, improves evacuation |
► Recommended Applications & Workpiece Materials
The Kyocera D91 1450 is ideally suited for the following materials and application scenarios:
- Steel Machining: Aluminum Alloys, Copper, Brass
- General Engineering: Structural components, shafts, housings, flanges
- Automotive: Engine blocks, transmission cases, brake components
- Aerospace: Titanium alloy structural elements (with adjusted parameters)
- Die & Mold: Precision holes in tool steel and hardened materials
- Energy Sector: Pump housings, valve bodies, pipeline components
► Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimal chip evacuation, minimal burr |
| Blind-Hole Drilling | ★★★★☆ Very Good | Use peck cycle for depths >3×D |
| High-Speed Drilling | ★★★★★ Excellent | Coating optimized for elevated temps |
| Precision Drilling | ★★★★★ Excellent | H7 tolerance achievable in stable conditions |
| Stack Drilling | ★★★☆☆ Good | Ensure rigid clamping, reduce feed 10% |
| Micro-Drilling | ★★★★☆ Very Good | Stable spindle required < 8,000 RPM |
► Recommended Cutting Conditions
| Material Group | Cutting Speed Vc (m/min) | Feed f (mm/rev) | Coolant |
|---|---|---|---|
| Low-Carbon Steel (< 0.25% C) | 40–55 | 0.05–0.10 | Emulsion / Internal |
| Medium-Carbon Steel (0.25–0.60% C) | 35–50 | 0.05–0.13 | Emulsion / Internal |
| High-Carbon Steel (> 0.60% C) | 30–45 | 0.03–0.10 | Internal / MQL |
| Stainless Steel (Austenitic) | 25–40 | 0.02–0.08 | Internal / High-pressure |
| Cast Iron (Gray / Ductile) | 50–65 | 0.08–0.15 | Dry / Compressed Air |
| Aluminum Alloys | 70–90 | 0.10–0.20 | Dry / MQL |
► Operating Guidelines
To maximize tool life and hole quality with the CDR00847, adhere to the following best practices:
- Runout Control: Maintain tool runout below 0.01 mm at the tool tip. Use precision collet chucks or hydraulic holders.
- Peck Drilling: For depths exceeding 3×D, employ a peck cycle with 1×D peck depth and 0.3×D retract.
- Coolant Delivery: Ensure internal coolant pressure ≥ 20 bar for effective chip evacuation. For external coolant, use high-flow nozzles directed at the cutting zone.
- Entry Angle: Use a chamfer or center drill to prevent wandering on inclined surfaces. Minimum chamfer: 0.2 mm × 45°.
- Speed Ramp: When starting a new tool, reduce cutting speed by 20% for the first 10 holes to break in the cutting edge.
- Tool Change Interval: Monitor flank wear (VB). Replace tool when VB = 0.3 mm or when surface finish degrades.
- Storage: Store in original packaging away from humidity. Avoid contact between cutting edges to prevent chipping.
► Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| ER Collet Chuck | ER16 / ER20 / ER25 | Use AA-grade collets for best runout |
| Hydraulic Chuck | HydroForce / Similar | Excellent damping, ideal for high-speed |
| Shrink Fit | HSK-A63 / HSK-E40 | Best for high-speed precision work |
| Weldon Shank | Side-lock holders | Acceptable for lower-speed applications |
