466.1: Denotes the specific tooling style code family (closely related to the multi-application 460.1 series).
1020: Indicates a 10.20 mm cutting diameter (DC).
032: Specifies the usable drilling depth capability, designed for 3xD (3 times the diameter) applications.
A1: Indicates a standard metric cylindrical shank configuration (DIN 6535-HA).
XM: Identifies the specialized chip breaker profile designed for multi-material efficiency.
Core Technical Features
SOlid Carbide Construction: Provides the high rigidity and heat resistance required for automated CNC machining lines.
Internal Coolant Channels: Features built-in micro-channels for axial concentric fluid flow. This allows high-pressure coolant (typically 20 bar) to deliver lubrication straight to the drill point, ensuring reliable chip evacuation and lower thermal wear
Multi-Material Versatility: Engineered to work seamlessly across different material groups including steels, stainless steels, and cast irons.
