The built-in insulating rubber ring prevents internal rusting and seizing,
blocks dust and debris from entering and damaging the bearings,
and avoids difficult tool installation or removal.
This prevents severe tool holder jamming and ensures usability.

The tool shank features a 360-degree precision arrangement of needle rollers,
delivering high load-bearing capacity for vibration-free, heavy-duty milling operations across wide ranges.
It ensures strong clamping force and high precision.

Thickened inner and outer walls enhance rigidity to withstand heavy cutting loads.
A unique slotted structure ensures uniform clamping without deformation,
achieving powerful holding force and stable runout accuracy.
