High-Performance HSS Roughing End Mill for Demanding Applications
The LV 9918WW is a coarse-pitch, long-flute roughing end mill manufactured from high-cobalt high-speed steel (HSS). This specialized composition provides exceptional wear resistance and a significantly extended service life, even under rigorous machining conditions. It is engineered for high-efficiency material removal, making it a reliable tool for heavy-duty roughing tasks.
Key Features & Benefits
- Premium High-Cobalt Steel: Constructed from high-grade HSS with an elevated cobalt content, ensuring superior hardness, heat resistance, and tool longevity.
- Long-Flute Design: The extended flute length is ideal for deep pocketing, slotting, and peripheral milling operations, allowing for greater depth of cut.
- Excellent Wear Resistance: The tool's material and geometry are optimized to withstand abrasive wear, resulting in consistent performance and reduced tool replacement costs.
- Optimized for Roughing: The coarse-pitch design facilitates rapid chip evacuation, preventing chip packing and enabling higher feed rates during rough machining.
Primary Applications
The LV 9918WW is specifically designed for machining low to medium hardness materials. It is highly effective for:
- Iron (e.g., Cast Iron, Ductile Iron)
- Carbon Steel (e.g., Low-carbon, Medium-carbon Steel)
- General Steel Alloys
