Key Performance & Features

Light Cutting Specialist: Engineered for low-to-medium load drilling, providing an exceptionally smooth cutting action in non-ferrous and soft materials.
Low-Friction ZK Chipbreaker: Multiple flow-guide grooves combined with dot protrusions reduce the contact area between chips and the rake face, suppressing heat buildup.
Superior Hole Quality: Optimized geometry guides chips to curl and fracture efficiently, ensuring excellent hole dimensional accuracy and surface smoothness.
Aluminum & Cast Iron Optimization: Specifically tuned for sticky materials like aluminum alloys and short-chip materials like cast iron.
Micro-Honed Edges: Precision micro-honing on the cutting edge ensures sharpness while maintaining enough stability for continuous light-duty CNC production.
