Product Overview
The Kyocera D89 0310 is a premium solid carbide drill engineered for high-precision hole-making in CNC machining centers. Manufactured in Japan from ultra-fine grain carbide, this drill delivers exceptional hole accuracy, superior surface finish, and extended tool life in demanding production environments.
With a diameter of 3.10 mm and advanced point geometry, the D89 0310 is optimized for precision drilling in carbon steel, alloy steel, stainless steel. Its rigid body design and optimized helix angle ensure stable chip evacuation and minimal deflection, even in deep-hole applications up to 3×D.

Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability | Recommended? |
|---|---|---|---|
| Carbon Steel | C45, C50, 1045, 1050 | ★★★★★ | ✓ Optimal |
| Alloy Steel | 4140, 4340, 8620 | ★★★★☆ | ✓ Optimal |
| Stainless Steel | 304, 316, 410, 420 | ★★★☆☆ | ✓ Good |
| Cast Iron | GG25, GGG40, FC250 | ★★★★☆ | ✓ Optimal |
| Tool Steel | H13, D2, O1 (≤ 35 HRC) | ★★☆☆☆ | ~ Conditional |
Application Map by Operation
| Operation | Suitability | Max Depth | Hole Tolerance |
|---|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | 3×D | H7–H8 |
| Blind-Hole Drilling | ★★★★☆ Very Good | 3×D | H8 |
| Spot Drilling | ★★★★★ Excellent | 0.5×D | Positioning |
| Chamfering | ★★★☆☆ Good | 0.2×D | Visual |
| Peck Drilling | ★★★★☆ Very Good | 5×D with peck | H8 |
Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fz (mm/rev) | Coolant |
|---|---|---|---|
| Carbon Steel (C45) | 100–140 | 0.10–0.18 | Emulsion 6–8% |
| Alloy Steel (4140) | 80–120 | 0.08–0.15 | Emulsion 6–8% |
| Stainless Steel (304) | 60–90 | 0.08–0.12 | High-pressure internal |
| Cast Iron (GG25) | 90–130 | 0.12–0.20 | Air blast acceptable |
| Tool Steel (H13) | 50–70 | 0.06–0.10 | Oil or high-performance coolant |
Start at the lower end of the range for new applications or less rigid setups. Increase speed gradually while monitoring tool wear and hole quality. For deep-hole drilling (>2×D), reduce feed by 15–20%.
Operating Guidelines
- Coolant: Flood coolant is essential for steel and stainless steel applications. For deep-hole drilling, use through-spindle coolant (TSC) at minimum 20 bar pressure.
- Runout: Maintain tool runout ≤ 0.01 mm at the tool tip. Excessive runout causes uneven wear and oversized holes.
- Pre-drilling: For holes > 2×D, consider a pilot hole at 0.5×D depth to ensure straight entry.
- Peck Cycle: Use peck drilling (Q) = 1×D for depths > 2×D. Retract fully to clear chips before subsequent pecks.
- Tool Life: Monitor corner wear and margin wear. Resharpening is not recommended for solid carbide drills. Replace when wear land exceeds 0.2 mm.
- Storage: Store in original protective tube. Avoid contact with other tools to prevent edge damage. Keep in dry environment.
Toolholder Compatibility
The D89 0310 features a cylindrical shank compatible with standard collet chucks, hydraulic chucks, and shrink-fit holders. Recommended holder systems:
| Holder Type | Taper / Interface | Max Runout | Best For |
|---|---|---|---|
| Hydraulic Chuck | HSK-A63, BT40, BT50 | ≤ 0.005 mm | High-precision finishing |
| Shrink-Fit Holder | HSK-A63, BT40, BT50 | ≤ 0.003 mm | High-speed machining |
| ER Collet Chuck | HSK-A63, BT40, BT50 | ≤ 0.015 mm | General purpose |
