Engineered for High-Performance Graphite Machining

The LV Tool 4DDMRS series is a 4-flute, deep-groove ball end mill specifically designed for the high-speed machining of abrasive and challenging materials. Its core strength lies in the advanced diamond coating, which provides exceptional hardness, superior wear resistance, and excellent thermal conductivity. These properties ensure a significantly longer tool life compared to conventional uncoated or standard coated end mills, reducing downtime and tooling costs for manufacturers.

Key Features and Benefits

Advanced Diamond Coating: Delivers extreme hardness for maximum abrasion resistance when machining graphite and composites.
4-Flute Ball Nose Design: Optimized for smooth and precise 3D contouring and finishing operations, ensuring excellent surface quality.
Deep Groove Geometry: Enhances chip evacuation, preventing clogging and maintaining stable cutting performance even in deep pocketing applications.
Extended Tool Life: The robust coating minimizes friction and heat buildup, drastically increasing the operational lifespan of the tool and lowering cost-per-part.
Versatile Application: Ideal for machining graphite electrodes, fiberglass reinforced plastics (FRP), carbon fiber reinforced plastics (CFRP), and other composite materials.
