Engineered for Stability and Performance
The 994L-UP series represents a significant advancement in carbide end mill technology, specifically designed by LV Tool for high-speed and high-efficiency machining. This 4-flute end mill incorporates a sophisticated unequal helix and unequal division geometry, a design proven to suppress chatter and vibration. By stabilizing the cutting process, it allows for higher feed rates and deeper cuts, ultimately reducing cycle times and improving productivity. The tool is constructed from premium micro-grain carbide rods, ensuring a tough and reliable foundation for challenging milling tasks on hardened materials.
Advanced Features for Demanding Applications
- Vibration-Dampening Design: The unequal helix and flute spacing effectively counteract harmonic vibrations, resulting in smoother cuts and superior surface quality.
- High-Performance AlTiSiN Coating: A specialized Aluminum Titanium Silicon Nitride coating provides an excellent thermal barrier and high hardness, protecting the tool from wear at elevated cutting temperatures and extending its operational life.
- Optimized Chip Evacuation: A unique double R-groove (U-flute) design facilitates efficient chip breaking and removal, preventing chip packing and ensuring consistent performance, especially in deep slotting and roughing operations.
- Premium Substrate: Manufactured from high-quality solid carbide for exceptional toughness, wear resistance, and rigidity under heavy loads.
- Post-Coating Treatment: A final polishing process after coating enhances surface lubricity and coating adhesion, further boosting tool life by up to 200-300%.
Recommended Applications
- Materials: Ideal for machining Mold Steel, Alloy Steel, Tool Steel, and other Heat-Treated Steels.
- Operations: Highly effective for roughing, slotting, and side milling where stability and chip control are critical.
