XOMT 04/05/06/07/08/09/11/13/15-PD | Inner Edge U-Drill Insert

ZANHO XOMT-PD series is a high-performance central/inner edge indexable drill insert specifically designed for paired use in "King Crown" style U-drills. Featuring a specialized granular chipbreaker, it effectively breaks chips at the low linear speeds found at the drill center, preventing stringy chip entanglement. Engineered with reinforced chamfered edges and a multi-corner polygonal structure, it provides exceptional impact resistance and cost-efficiency for drilling carbon steel, alloy steel, and cast iron.

Key Performance & Features

Specialized Inner Edge Design: Specifically optimized for the central position of indexable drills where cutting conditions are most severe due to near-zero linear speed.
Granular Chipbreaker Structure: Multiple protrusions force chips to fragment into short grains, preventing the formation of ribbon-like chips that cause hole clogging.
Reinforced Tip Integrity: Heavily chamfered cutting edges are designed to withstand the intense axial impact at the drill core, reducing the risk of sudden tool failure.
Economic Multi-Edge Geometry: Polygonal structure provides multiple usable cutting corners per insert, maximizing tool utilization and lowering the cost-per-hole.
System Compatibility: Engineered to work in perfect synchronization with SPMT outer inserts for balanced drilling forces and superior hole tolerance.
