Frequently Asked Questions

1. How does a hydraulic tool holder differ from a mechanical collet chuck? ▼

Hydraulic tool holders from PAC Tools use internal oil pressure to apply even clamping force around the tool shank. This provides better accuracy, vibration damping, and easier tool changes compared to mechanical collet chucks.

2. What materials are best suited for hydraulic tool holders? ▼

PAC Tools hydraulic holders work best with tools made of solid carbide or high-speed steel (HSS) with h6 tolerance. These materials ensure a secure fit and high-performance in precision machining.

3. Can I use hydraulic tool holders for reaming or finishing? ▼

Yes, PAC Tools hydraulic holders are ideal for reaming, fine boring, and finishing operations. Their superior runout control and vibration damping enhance surface finish and tool life.

4. How do I insert a tool into a hydraulic chuck correctly? ▼

To insert a tool, align it to the proper depth mark, then tighten using the hydraulic key or screw as per PAC Tools’ instructions. Ensure the bore and shank are clean to maintain precision.

5. Can I use torque limiting tools or gauges with hydraulic holders? ▼

Yes, PAC Tools hydraulic holders are compatible with torque-limiting tools. This prevents over-tightening, ensures safe tool clamping, and maintains consistent machining accuracy.

6. How do I ensure maximum runout control during tool setup? ▼

Use high-quality h6 shank tools, clean all contact surfaces, and follow PAC Tools’ insertion guidelines. Proper setup and maintenance are key to achieving runout as low as 3 microns.
