880-P-GM Series | Peripheral Indexable Drill Insert

ZANHO 880-P-GM series is a high-performance peripheral indexable drill insert engineered for the outer edge position of multi-edge drills. Featuring an integrated wiper structure, it ensures exceptional hole tolerance and surface integrity even at low-to-medium feed rates. Optimized for machines with lower power or long tool overhangs, its light-cutting geometry effectively suppresses vibration while providing stable chip control across diverse materials including steel, stainless steel, and tough alloys.

Key Performance & Features

Wiper Technology Integration: Features a specialized wiper edge that smooths the hole wall during drilling, delivering superior surface finish and tighter dimensional tolerances.
Vibration Suppression: Specifically designed to reduce the cutting load on the peripheral edge, making it the ideal choice for setups with limited machine rigidity or large tool overhangs.
Universal Chip Control: The GM chipbreaker geometry is optimized to fragment chips into short segments across multiple material groups, preventing long ribbons from scratching the finished hole.
Balanced Cutting Action: Bridges the gap between edge strength and sharpness, providing stable, long-lasting performance in continuous CNC production.
Broad Application Range: One insert solution for Carbon Steel, Stainless Steel, Cast Iron, High-Temperature Alloys, and Hardened Steel.
