Product Overview
The Kyocera #35 DRILL 2FL TC SGS58410 is a premium solid carbide twist drill engineered for high-performance holemaking in CNC machining centers. Featuring a 2-flute design with a 140° point angle and 30° helix angle, this tool delivers exceptional chip evacuation, superior hole quality, and extended tool life in demanding production environments. The ultra-fine grain carbide substrate combined with an advanced PVD coating ensures stable performance across a broad spectrum of workpiece materials.

Chipbreaker Profile
The SGS58 series employs a precision-ground helical flute geometry with an optimized chipbreaker land width of 0.42 mm. The flute profile features a 0.70 mm rake face and a controlled clearance angle of 8°–10°, promoting efficient chip curling and evacuation. This design minimizes built-up edge (BUE) in ductile materials and reduces cutting forces by up to 15% compared to standard geometries, ensuring stable drilling depth-to-diameter ratios of up to 5×D in steels and 8×D in aluminum alloys.

Recommended Cutting Conditions
| Workpiece Material | Cutting Speed (Vc) | Feed per Rev (fn) | Coolant |
|---|---|---|---|
| Carbon Steel (C45) | 40-60 m/min | 0.05-0.10 mm/rev | Internal / External |
| Stainless Steel (304) | 25-40 m/min | 0.05-0.10 mm/rev | High-pressure internal |
| Aluminum Alloy (6061) | 80-120 m/min | 0.05-0.10 mm/rev | Mist / Air blast |
| Cast Iron (GG25) | 40-60 m/min | 0.05-0.10 mm/rev | Dry / Compressed air |
| Titanium (Ti-6Al-4V) | 20–35 m/min | 0.05-0.10 mm/rev | High-pressure internal |
Note: Values are starting recommendations. Optimize based on machine rigidity, workpiece setup, and coolant delivery. Reduce Vc by 20% for depth-to-diameter ratios > 3×D.
Operating Guidelines
- Run-out check: Ensure spindle run-out is < 0.01 mm at the tool tip to prevent premature corner chipping.
- Peck cycle: For depths > 3×D, use a peck depth of 1×D–1.5×D with full retract to clear chips.
- Coolant pressure: Maintain minimum 20 bar (290 psi) internal coolant pressure for holes > 2×D.
- Entry angle: Use a 90° entry or chamfer the hole entrance to avoid drill walk on inclined surfaces.
- Speed ramp: Gradually ramp spindle speed over 3–5 seconds to avoid thermal shock to the carbide.
- Tool change: Inspect flank wear (VB) after every 50 holes; regrind or replace when VB > 0.2 mm.
- Storage: Store in original packaging at < 40% humidity to protect coating integrity.
