Hydraulic Chuck Series

■ Power Hydraulic Chuck “PHC-A”
NT Tool’s standard hydraulic chuck type. It achieves high precision with a runout accuracy of 3 μm at a 4D projection.
Its unique hydraulic chamber mechanism provides excellent vibration damping performance, resulting in a superior surface finish during cutting operations.

■ Slim Hydraulic Chuck “PHC-SB”
An ideal holder for not only interference-prone drilling and reaming operations, but also 5-axis finishing with end mills. This upgraded model features an even slimmer design than its predecessor, while maintaining a high runout accuracy of 3 μm—making it a high-precision, slim hydraulic chuck.

■ Hydraulic Chuck Omega “PHC-H”
A high-clamping-force, high-precision holder that prevents tool slippage, chatter, and deflection—even during heavy-duty machining.
It minimizes uncut areas on the workpiece, reduces the need for zero-cut finishing, and lowers the load on subsequent processes, contributing to shorter cycle times.
