Product Details

Hard alloy round bar used for making milling cutters

Material & Durability

Engineered for Resilience. Crafted from premium YG6X and YG8 solid carbide, our tools strike the perfect balance between extreme hardness and industrial-grade toughness. This "Tough-Hard" synergy ensures the tool can withstand high-speed vibrations without chipping.

Precision Manufacturing

Ultra-Smooth Chip Evacuation. Each bit is fully ground with a mirror-finish flute to minimize friction. The high-precision concentricity (h6 tolerance) ensures that your digital cutter produces perfectly vertical edges on thick acrylic and PVC boards.

 

Standard 3mm, 3.175mm (1/8"), 4mm, and 6mm shanks available to fit most high-speed spindles.

Performance at Speed

High-RPM Stability. Optimized for spindles reaching up to 60,000RPM. Our specialized spiral geometry prevents "material re-welding" (melting) by efficiently ejecting hot chips away from the cutting path—critical for heat-sensitive plastics.

 

Optimized 35° or 45° spiral angles ensure smooth chip evacuation and a superior surface finish.

Tailored Solutions

Fully Customizable Geometry. We offer more than just standard sizes. From Single-Flute Spiral for soft plastics to Multi-Flute for aluminum and composites, we provide custom helix angles and advanced coatings (TiAlN/DLC) to triple your tool life.

 

Optimized Spiral Angle: Our tools feature a unique spiral geometry that forces chips upwards and away from the cut, preventing material re-welding and heat buildup.
