How does a power milling holder achieve high clamping force?

PAC Tools power milling holders use a mechanical wedge or cam system to apply strong, uniform pressure on the tool shank. This results in exceptionally high clamping force for stable, heavy-duty machining.

Is a power milling chuck suitable for both solid carbide and HSS tools?

Yes, PAC Tools power chucks are compatible with both solid carbide and HSS tools. They offer secure clamping and high performance across a wide range of materials and tool types.

What is the typical clamping torque generated?

PAC Tools power milling holders can generate clamping torque ranging from 200 to 600 Nm, depending on the holder size. This makes them ideal for aggressive milling and roughing operations.

Can I use a power milling holder for interrupted cutting?

Yes, PAC Tools power holders are built for tough conditions, including interrupted cuts. Their rigid grip minimizes tool deflection and vibration, ensuring reliable performance in demanding operations.

Can power chucks be used with shell or face mills?

Yes, PAC Tools power chucks can be used with shell mills and face mills when equipped with appropriate adapters or arbor interfaces. They deliver the rigidity needed for accurate surface machining.
