Robust Material: High Hardness, Wear Resistance & Longer Service Life
Adopting ultra-fine grain tungsten carbide (cemented carbide) with a hardness of HRA91+ (≈HRC80), it far outperforms high-speed steel. Boasting excellent chipping and impact resistance, its cutting edge resists wear even during continuous machining. It delivers a 3 to 5 times longer service life than conventional cutters, significantly reducing tool change frequency.
Triple-flute Design: Stable Cutting, Fast Chip Evacuation & High Efficiency
It combines the superior chip evacuation capability of 2-flute cutters with the high rigid strength of 4-flute cutters, featuring balanced cutting force, excellent vibration resistance and chatter-free machining. Equipped with U-shaped large chip flutes with internal polishing, it enables smooth chip removal without chip adhesion or winding, supports deep cutting and high feed rate, and boosts machining efficiency by 50% to 100% compared with conventional cutting tools.
Colorful Coating: Low Friction, High Surface Finish & High Temperature Resistance
This colorful coating is a DLC diamond-like carbon/nano-TiAlN composite coating with a friction coefficient as low as 0.1-0.2, effectively preventing aluminum chip adhesion and eliminating built-up edges. It endures temperatures above 800℃ without deformation during high-speed cutting, and achieves a surface roughness of Ra0.8-1.6μm with a high-gloss/mirror finish, eliminating the need for subsequent polishing.
Versatile Machining & Stable Precision
Featuring a fully ground precision cutting edge with sharpness and no burrs, it enables one-step rough and finish milling. Compatible with CNC high-speed machining, it is ideal for processing soft materials such as aluminum alloys, copper alloys, acrylics and plastics, delivering outstanding dimensional accuracy and consistent surface finish.
