Dynabrade 51857 Compact Air Router 0.7 Hp 20000 Rpm

Product Description

The DYNABRADE 51857 is a compact pneumatic router designed for precision material removal, trimming, and routing tasks in industrial and trade environments. Powered by compressed air, it delivers 0.7 hp and spins at 20,000 RPM through a 1/4 inch collet, making it well-suited for controlled, high-speed routing in tight workspaces. The tool connects via a 1/4 NPT inlet and requires 90 psi supply pressure with an air consumption of 38 CFM. It is typically installed and operated by millwrights, maintenance technicians, woodworking professionals, and fabricators working in production or shop settings.

The 51857 is built for compact router applications where a smaller tool footprint is needed without sacrificing rotational speed. It fits into routing jigs, laminate trimming setups, and light-duty material shaping operations across woodworking, composites, and light metalworking trades. Its pneumatic drive makes it well-matched to environments where electric tools are restricted or where continuous-duty operation is required on an air supply already serving other tools at the work station.

Key Features

• 20,000 RPM free speed supports high-speed routing and trimming operations
• 0.7 hp pneumatic motor delivers consistent power from a standard shop air supply
• 1/4 inch collet accepts common router bit shanks used in trade and production work
• 1/4 NPT air inlet fits standard pneumatic fittings and quick-connect couplers
• 90 psi operating pressure is compatible with typical industrial compressed air systems
• Compact form factor allows use in confined spaces and routing jig applications

Compatibility

Designed as a compact pneumatic router compatible with standard 1/4 inch collet router bits and 1/4 NPT compressed air supply lines operating at 90 psi.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety practices. Before connecting or disconnecting the tool, depressurize the air line and verify the supply pressure does not exceed the rated 90 psi maximum. Use a properly sized air regulator, filter, and lubricator in the supply line to protect the motor and maintain consistent performance. Ensure all collet and bit connections are fully secured before applying air pressure to the tool.
