Lathe Tool Holder Proxxon PD 400 — Proxxon precision tool post for PD 400 lathe

The Proxxon PD 400 lathe tool holder is a precision tool post designed to secure cutting tools on the Proxxon PD 400 lathe. It accepts interchangeable tool bits and provides a stable mounting platform on the lathe carriage, allowing accurate positioning for turning, facing and light machining operations on small metal and wood workpieces. The tool holder is intended for hobbyists and small workshop applications where compact size and repeatable alignment are required.

Advantages

The tool post offers rigid clamping of cutting tools to reduce vibration and maintain consistent cutting geometry during light machining. Its compact design integrates with the lathe carriage without significantly increasing overall tool overhang, supporting precise, repeatable tool placement. Construction and fitment are matched to the lathe model to simplify installation and adjustment, enabling controlled depth of cut and smoother surface finishes on small parts.

Suitable for

• Turning and facing small diameter shafts and rods
• Light profiling and finishing on metal and wood components
• Repeating simple operations where fixed tool angles are sufficient
• Hobby model making, repair work and small batch production

Key specifications

• Compatible mounting interface for the Proxxon PD 400 lathe carriage
• Accepts standard interchangeable square or rectangular tool bits suitable for small lathes
• Compact footprint to minimize tool overhang and preserve clearance
• Rigid clamping mechanism for stable tool retention during light cuts
• Suitable for precision work on small metal and wooden parts

How to use

Fit the tool holder to the lathe carriage following the lathe manufacturer’s instructions to ensure correct orientation and secure fastening. Install a suitably sized tool bit into the tool holder, align it to the lathe center height, and clamp firmly. Set the tool angle and position for the intended operation, then perform test cuts at light depths to confirm alignment and clearances before proceeding with final machining passes.

Usage recommendations

Use sharp, appropriately profiled tool bits and make light finishing cuts to preserve part accuracy and surface quality. Regularly check and retighten clamping screws and confirm tool center height after tool changes. For heavier cutting or interrupted cuts, consider tools and fixtures rated for higher rigidity and larger machines.
