Kyocera D83 0310 CDR01332 — Solid Carbide Micro-Drill
► Product Overview
The Kyocera D83 0310 (MPN: CDR01332) is a precision-engineered solid carbide micro-drill designed for high-precision CNC machining operations. With a nominal diameter of 3.1 mm, this compact tool delivers exceptional dimensional accuracy, superior hole quality, and extended tool life in demanding micro-machining applications. Manufactured in Japan to stringent ISO 9001 quality standards, the D83 series is optimized for small-diameter drilling where precision is paramount.

| MPN | CDR01332 | Manufacturer Part Number (unique identifier) |
| ISO Class | K | Primary workpiece material classification |
| Coating | PVD TiCN | Surface treatment for heat/wear resistance |
► Engineering Dimensions & Geometry
| Parameter | Specification | Tolerance |
|---|---|---|
| Nominal Diameter (D) | 3.1 mm | h7 (±0.005 mm) |
| Overall Length (L) | 38 mm | ±0.3 mm |
| Flute Length (l) | 12 mm | ±0.2 mm |
| Shank Diameter (d) | 3.1 mm | h6 |
| Point Angle | 135° | ±1° |
| Helix Angle | 35° | ±1° |
| Number of Flutes | 2 | — |
| Corner Radius | Standard | ±0.003 mm |
► Grade Details — Key Grade Characteristics
The D83 series utilizes Kyocera's proprietary ultra-fine micro-grain carbide substrate combined with an advanced PVD TiCN multi-layer coating system. This synergistic combination delivers:
- Ultra-fine grain structure (0.3 μm) for superior edge sharpness and micro-fracture resistance
- PVD TiCN coating providing exceptional thermal stability up to 850°C
- High hardness (HRA 93.0) ensuring minimal wear in high-speed micro-machining
- Optimized cobalt binder (6%) balancing hardness with toughness for small diameters
- Low friction coefficient reducing built-up edge and improving chip evacuation in confined spaces
► Grade Comparison Matrix
| Property | D83 0310 | Standard Grade | Competitor A |
|---|---|---|---|
| Hardness (HRA) | 93.0 | 91.5 | 92.0 |
| Transverse Rupture (MPa) | 4,200 | 3,500 | 3,800 |
| Coating Thickness (μm) | 1.8 | 1.2 | 1.5 |
| Max Cutting Temp (°C) | 850 | 700 | 750 |
| Tool Life Index | 100% | 72% | 80% |
► Chipbreaker Profile
The D83 0310 features a precision-ground chipbreaker geometry specifically engineered for Ø3.1 mm micro-drilling operations. The narrow flute profile incorporates a variable helix design with mirror-polished rake surfaces to ensure smooth chip formation and evacuation in small-diameter holes. The proprietary edge preparation minimizes burr formation and reduces cutting forces by up to 18% compared to conventional micro-drill geometries.
| Geometric Feature | Value | Function |
|---|---|---|
| Rake Angle (γ) | 10°–14° | Reduces cutting force, improves chip flow |
| Relief Angle (α) | 8°–10° | Minimizes flank wear, prevents rubbing |
| Edge Preparation | T-land + micro-hone | Enhances edge stability, prevents chipping |
| Flute Polishing | Ra 0.1 μm | Reduces chip adhesion, improves evacuation |
► Recommended Applications & Workpiece Materials
The Kyocera D83 0310 is ideally suited for the following materials and application scenarios:
- Steel Machining: Titanium Alloys, Inconel, Hastelloy
- General Engineering: Precision holes in small components, electronic housings, medical devices
- Automotive: Fuel injector nozzles, sensor housings, valve guides
- Aerospace: Titanium alloy structural elements, heat exchanger tubes
- Die & Mold: Micro-cooling channels, ejector pin holes, venting channels
- Medical: Surgical instrument components, implant fixtures
► 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 >2×D |
| High-Speed Drilling | ★★★★☆ Very Good | Max 15,000 RPM for Ø3.1 mm |
| Precision Drilling | ★★★★★ Excellent | H7 tolerance achievable in stable conditions |
| Deep-Hole Drilling | ★★★☆☆ Good | Max 5×D without pecking; use coolant |
| Micro-Drilling | ★★★★★ Excellent | Stable spindle required < 15,000 RPM |
► Recommended Cutting Conditions
| Material Group | Cutting Speed Vc (m/min) | Feed f (mm/rev) | Coolant |
|---|---|---|---|
| Low-Carbon Steel (< 0.25% C) | 37–47 | 0.040–0.070 | Emulsion / Internal |
| Medium-Carbon Steel (0.25–0.60% C) | 34–44 | 0.040–0.090 | Emulsion / Internal |
| High-Carbon Steel (> 0.60% C) | 31–41 | 0.030–0.070 | Internal / MQL |
| Stainless Steel (Austenitic) | 29–39 | 0.030–0.060 | Internal / High-pressure |
| Cast Iron (Gray / Ductile) | 42–52 | 0.060–0.100 | Dry / Compressed Air |
| Aluminum Alloys | 57–72 | 0.070–0.120 | Dry / MQL |
► Operating Guidelines
To maximize tool life and hole quality with the CDR01332, adhere to the following best practices for micro-drilling:
- Runout Control: Maintain tool runout below 0.005 mm at the tool tip. Use precision collet chucks or shrink-fit holders.
- Peck Drilling: For depths exceeding 2×D, employ a peck cycle with 0.5×D peck depth and 0.2×D retract.
- Coolant Delivery: Ensure internal coolant pressure ≥ 30 bar for effective chip evacuation in small holes. For external coolant, use micro-nozzles directed at the cutting zone.
- Entry Angle: Use a center drill or spot drill (90°–120°) to prevent wandering. Spot depth should be 0.5–1.0 mm.
- Speed Ramp: When starting a new tool, reduce cutting speed by 25% for the first 20 holes to break in the cutting edge.
- Tool Change Interval: Monitor flank wear (VB). Replace tool when VB = 0.1 mm or when hole diameter tolerance is exceeded.
- Storage: Store in original packaging away from humidity and vibration. Avoid contact between cutting edges to prevent micro-chipping.
► Toolholder Compatibility
| Holder Type | Compatibility | Recommendation |
|---|---|---|
| ER Collet Chuck | ER11 / ER16 | Use AAA-grade collets for best runout |
| Hydraulic Chuck | Micro hydraulic / Similar | Excellent damping, ideal for micro-machining |
| Shrink Fit | HSK-E32 / HSK-E40 | Best for high-speed precision work |
| Collet Block | Precision drill chucks | Acceptable for lower-speed applications |
