1. Product Overview
The Kyocera SGS34517 is a premium 2FL square weldon flat engineered for demanding CNC milling operations. Featuring a 1/2 (0.500") cutting diameter featuring a sharp 90° corner for precise square shoulder milling, this solid carbide endmill is optimized for general machining, mold & die, aerospace components. Manufactured in Japan to exacting tolerances, the SGS34517 combines an ultra-fine grain carbide substrate with an advanced PVD coating to deliver exceptional tool life, superior surface finish, and reliable performance in high-speed machining environments.

6. Chipbreaker Profile
While endmills do not feature traditional insert-style chipbreakers, the SGS34517 incorporates advanced flute geometry that functions as an integrated chip management system:
- Variable Helix Design: Unequal flute spacing minimizes harmonic vibration and chatter, improving surface finish and tool life.
- Positive Rake Face: Optimized rake angle reduces cutting forces and heat generation, enabling smooth chip evacuation.
- Core Thickness: Reinforced core design provides rigidity for aggressive milling parameters without deflection.
- Flute Profile: Parabolic flute form with polished surfaces ensures efficient chip flow, preventing recutting and built-up edge.
- Edge Preparation: Chamfered edge (0.1×45°) balances sharpness with edge durability for the intended workpiece range.
7. Recommended Applications & Workpiece Materials
The PR1535 grade and 1/2 2FL geometry make the SGS34517 ideally suited for the following materials and industries:
| Workpiece Material | Machinability | Recommended Operation |
|---|---|---|
| Tool Steel (H13, D2, A2) | Excellent | Roughing to finishing |
| Inconel & Nickel Superalloys | Very Good | Semi-finishing & finishing |
| Stainless Steel (304, 316, 17-4PH) | Good | Profiling & cavity milling |
| Titanium Alloys (Ti-6Al-4V) | Good | High-speed finishing |
Industries: Aerospace, Automotive, Mold & Die, Medical Device Manufacturing, General Engineering.
8. Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| Roughing | Excellent | High material removal rates, stable chip formation |
| Semi-Finishing | Good | Balanced speed and surface quality |
| Finishing | Very Good | Mirror finish capability on pre-hardened steels |
| Profiling | Recommended | Precise contour following, minimal deflection |
| Cavity Milling | Ideal | Deep cavity access with efficient chip evacuation |
9. Recommended Cutting Conditions
The following parameters are starting recommendations for the SGS34517. Adjust based on machine rigidity, workpiece material, and desired surface finish:
| Parameter | Symbol | Recommended Range | Unit |
|---|---|---|---|
| Cutting Speed | Vc | 120-180 | m/min |
| Feed per Tooth | fz | 0.08-0.15 | mm/tooth |
| Axial Depth of Cut | ap | 1.0-3.0 | ×D |
| Radial Depth of Cut | ae | 0.3-0.5 | ×D |
| Spindle Speed (approx.) | n | 3,000-12,000 | RPM |
| Coolant Strategy | — | Air blast / MQL / Flood | — |
Note: For hardened steels (>45 HRC), reduce Vc by 15-20% and use air blast or MQL to prevent thermal cracking.
10. Operating Guidelines
- Runout Check: Ensure toolholder TIR is less than 0.005 mm (0.0002") to prevent uneven wear and premature failure.
- Ramping: Use helical ramp entry with a maximum angle of 2° for pocketing operations to minimize impact loading.
- Plunging: Center-cutting capability allows direct axial plunging at 30-50% of recommended feed rate.
- Chip Evacuation: Maintain adequate coolant pressure or compressed air to clear chips from the cutting zone, especially in deep cavities.
- Tool Life Monitoring: Inspect cutting edges after every 30 minutes of machining; replace when flank wear exceeds 0.15 mm or chipping is visible.
- Storage: Store in original packaging away from moisture and corrosive environments to preserve coating integrity.
11. Toolholder Compatibility
The SGS34517 features a precision-ground shank compatible with industry-standard toolholding systems:
| Toolholder Type | Compatible Series | Max Runout |
|---|---|---|
| ER Collet Chuck | ER20, ER25, SYIC 1/2", Techniks 1/2" | ≤0.005 mm |
| Hydraulic Chuck | Schunk, Haimer, Mapal | ≤0.003 mm |
| Shrink Fit | Haimer, Bilz, Rego-Fix | ≤0.002 mm |
| Milling Chuck | NT Tool, BIG Kaiser | ≤0.005 mm |
Recommendation: For maximum performance and tool life, use a hydraulic or shrink-fit toolholder with runout ≤0.003 mm.
