Product Overview
The Kyocera 3,2 DRILL 2FL SGS61069 is a premium-grade solid carbide drill featuring the PR1535 substrate. Engineered for high-precision holemaking in CNC machining centers, this tool delivers exceptional dimensional accuracy, superior surface finish, and extended tool life across a broad spectrum of workpiece materials. The optimized 2-flute geometry ensures efficient chip evacuation and minimal cutting forces, making it ideal for both through-hole and blind-hole applications in high-volume production environments.

Chipbreaker Profile
The SGS series features a polished flute surface with an optimized chipbreaker geometry designed for 3.2-mm diameter drilling. The chipbreaker ensures:
- Controlled chip curling with a radius of 1.1 mm
- Reduced cutting force by 15% compared to standard geometries
- Prevention of chip packing in deep-hole applications up to 6×D
- Smooth chip evacuation through polished flutes (Ra 0.2 μm)
- Minimized built-up edge (BUE) on sticky materials like stainless steel

|---|---|---|---|
| Through-hole Drilling | ★★★★★ | 5×D | Optimal chip evacuation |
| Blind-hole Drilling | ★★★★☆ | 3×D | Use peck cycle for >2×D |
| Stack Drilling | ★★★★☆ | — | Ensure clamping rigidity |
| Cross-hole Drilling | ★★★☆☆ | 2×D | Reduce feed by 30% |
| Enlarging | ★★★★☆ | 3×D | Pre-drill with smaller diameter |
Recommended Cutting Conditions
| Material | Vc (m/min) | fn (mm/rev) | RPM (approx.) |
|---|---|---|---|
| Carbon Steel (roughing) | 73 | 0.104 | 7261 |
| Carbon Steel (finishing) | 93 | 0.07 | 9250 |
| Stainless Steel 304 | 51 | 0.083 | 5083 |
| Cast Iron GG25 | 80 | 0.125 | 7987 |
| Aluminum 6061 | 232 | 0.156 | 23127 |
| Titanium Ti-6Al-4V | 29 | 0.062 | 2904 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant pressure, and workpiece clamping. Use internal coolant (20+ bar) for optimal performance.
Operating Guidelines
- Run-in Period: Reduce feed by 20% for the first 50 holes to stabilize cutting edge micro-geometry.
- Coolant: Water-miscible coolant (6-8% concentration) at 20+ bar pressure. Minimum flow rate 8 L/min.
- Pecking: For depths >2×D, use a peck cycle with retract to 0.5×D above hole bottom.
- Entry Angle: Ensure perpendicular entry (±0.5°) or use a spot drill to prevent chipping.
- Exit Strategy: Reduce feed by 50% in the last 1 mm to prevent burr formation on through-holes.
- Tool Life Monitoring: Replace when flank wear (VB) reaches 0.15 mm or when surface roughness exceeds Ra 1.6 μm.
- Storage: Store in original packaging at 15-25°C with <60% humidity to prevent coating degradation.
