Product Overview
The Kyocera 3/4 2FL Square End Solid Carbide Endmill (MPN: SGS33335) is a premium-grade cutting tool engineered for slotting operations in modern CNC machining centers. Manufactured from Fine grain carbide and finished with TiAlN (Titanium Aluminum Nitride) coating, this endmill delivers exceptional wear resistance, thermal stability, and extended tool life under demanding cutting conditions. The 2FL design with 30° helix angle is optimized for aluminum, non-ferrous metals, plastics, ensuring superior chip evacuation and minimal cutting forces.

Chipbreaker Profile
Wide-flute design with center-cutting capability and polished rake face for efficient chip removal in slotting and plunging operations.
- Precision-ground cutting edges with edge preparation (T-land + hone) for improved edge stability
- Polished flute surfaces reduce friction and prevent material buildup during aluminum and stainless steel machining
- Variable pitch design minimizes harmonic vibration and chatter in high-speed operations
- Core-thinning geometry at the end teeth enhances center-cutting performance and plunge capability

Note: Values are starting recommendations. Optimize based on machine rigidity, coolant delivery, and workpiece clamping. Use high-pressure coolant for stainless steel and titanium applications.
Operating Guidelines
- Runout Control: Maintain tool runout below 0.01 mm (0.0004") at the cutting edge to prevent uneven wear and premature failure.
- Coolant Strategy: Use water-soluble coolant at 6–8% concentration for steel and cast iron. For aluminum, apply flood coolant or MQL to prevent built-up edge.
- Chip Evacuation: Ensure adequate air blast or coolant pressure to clear chips from the cutting zone, especially in deep cavity milling and slotting.
- Speed Ramp: When starting a new tool, reduce cutting speed by 20% for the first 5 minutes to allow the coating to "season" and achieve optimal adhesion.
- Tool Life Monitoring: Monitor flank wear (VB). Resharpen or replace when VB exceeds 0.2 mm for roughing or 0.1 mm for finishing operations.
- Vibration Damping: Use shortest possible overhang. For L/D ratios exceeding 4:1, consider using vibration-damping toolholders or reduced cutting parameters.
Toolholder Compatibility
