Key Performance & Features

Trigon Geometry Specialist: Designed for high-efficiency indexable drills, utilizing a unique triangle shape with 2 effective cutting edges for balanced drilling forces.
Advanced Chip Control: The ring-shaped flow guide cavity optimizes chip fragmentation and guides them out of the hole, perfectly suited for U-drills with internal coolant systems.
Reinforced Edge Integrity: Negative land treatment on the cutting edge significantly enhances resistance to micro-chipping and handles the impact of forging crusts or oxide layers.
Inner/Outer Pairing Logic: Engineered for precision paired assembly; ensure correct inner and outer edge insert placement to achieve optimal hole diameter and surface finish.
Broad Material Versatility: A robust general-purpose solution for Carbon Steel, Alloy Steel, Cast Iron, and general Stainless Steel, reducing workshop inventory requirements.
