55" Reach Pneumatic Tapping Arm - 400 RPM

55" Reach Pneumatic Tapping Arm - 400 RPM Overview

The Palmgren 55" Reach Pneumatic Tapping Arm is part of the Production-Tap series and is designed for a wide range of general-purpose to heavy-duty tapping applications. Its articulated arm design provides smooth positioning across a large work area, allowing operators to bring the tap directly to the hole on large or multi-level parts.

The arm is equipped with lubricated-for-life bearings at all swivel points and provides weightless operation throughout its working range.

Key Benefits

• Maximum tapping capacity: 9/16" in aluminum.

Ideal Uses & Work Environments

The Palmgren 55" Reach Pneumatic Tapping Arm is well suited for machine shops, fabrication facilities, maintenance departments, and production environments that perform frequent tapping operations. The extended 55-inch reach allows operators to work efficiently across large weldments, fabricated assemblies, plates, frames, and other oversized components without repeatedly repositioning the workpiece.

In addition to creating new threads, the system can be used for re-tapping damaged or heat-treated holes, as well as secondary operations such as reaming, countersinking, chamfering, and finishing. Its versatility makes it a practical solution for both job shops and manufacturing operations looking to improve throughput and reduce manual effort during secondary machining processes.

Designed to Address Common Shop Challenges

Tapping large or awkwardly shaped parts often requires operators to reposition heavy workpieces, move between machines, or perform repetitive manual operations that consume valuable production time. The Shop-Tap pneumatic tapping arm helps eliminate many of these inefficiencies by bringing the tap directly to the workpiece instead of moving the workpiece to the tap.

The extended reach and articulated arm design improve access to difficult tapping locations while reducing operator fatigue during repetitive operations. By simplifying hole positioning and thread creation, the system helps shops complete tapping operations more efficiently and maintain consistent results across production runs.

How to Choose the Right Palmgren Tapping Arm

Palmgren offers pneumatic tapping systems for everything from compact workstations to large production environments. Quick-Tap models provide a compact 37" working envelope for small to medium tapping applications. Shop-Tap models extend reach to 62" for greater coverage across large workpieces. Production-Tap models provide a 55" working envelope and are designed for general-purpose through heavy-duty tapping operations. For shops requiring variable speed control and support for larger tap sizes, the Universal-Tap electric system provides additional flexibility.
