Product Overview
The Kyocera #17 DRILL 2FL TA SGS56226 is a premium solid carbide drill engineered for high-performance CNC machining. Designed with a DLC-coated sub-micron grain carbide (0.8 μm), this tool delivers exceptional wear resistance, thermal stability, and dimensional accuracy across demanding production environments. The optimized 2-flute geometry ensures efficient chip evacuation and reduced cutting forces, making it ideal for precision hole-making operations in cast iron, ductile iron, grey iron.

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Through-Hole Drilling | ★★★★★ Excellent | Optimal chip evacuation with 2-flute design |
| Blind-Hole Drilling | ★★★★☆ Very Good | Use peck cycle for depths >3×D |
| Counterboring | ★★★★☆ Very Good | Reduce feed by 20% for best surface finish |
| Spot Drilling | ★★★★★ Excellent | Self-centering 140° point angle |
| Micro-Drilling | ★★★☆☆ Good | Requires rigid setup and high-pressure coolant |
Recommended Cutting Conditions
| Parameter | Range | Optimal |
|---|---|---|
| Cutting Speed (V_c) | 50 – 110 m/min | 70 m/min |
| Feed per Revolution (f_n) | 0.09 – 0.24 mm/rev | 0.14 mm/rev |
| Depth of Cut (a_p) | Up to 3.0 × D | 1.8 × D |
| Coolant Pressure | 20 – 70 bar (recommended) | 40 bar |
| Coolant Type | Emulsion (8-10%) or MQL | Emulsion with EP additives |
Operating Guidelines
- Runout: Maintain spindle runout ≤ 0.01 mm for optimal tool life and hole quality.
- Peck Cycle: For holes deeper than 3×D, use a peck depth of 1–1.5×D with full retract to break chips.
- Entry Angle: Ensure perpendicular entry (±1°) to prevent chipping of the cutting edges.
- Coolant: High-pressure through-spindle coolant is strongly recommended for holes >2×D.
- Pre-Drilling: Not required for standard applications; tool is self-centering with 140° point geometry.
- Speed/Feed Ramp: Ramp up to full cutting parameters over the first 2–3 holes to avoid thermal shock.
