Dynabrade 57400 Inline Finishing Sander 0.3 Hp

Product Description

The DYNABRADE 57400 is a pneumatic inline finishing sander designed for surface finishing and detail sanding work in industrial and trade environments. Rated at 0.3 horsepower, it draws 18 SCFM of air and operates at an inlet air pressure of 90 psi (6.21 bar). The tool accepts a 1/4 NPT air inlet fitting. At 2.6 pounds and 7 inches in overall length, it is compact enough for work in confined areas and light enough for extended use. This tool is typically installed and operated by industrial maintenance technicians, metal fabricators, auto body technicians, and woodworking professionals who require a controlled, low-profile sanding tool.

The 57400 is suited for inline finishing applications where the tool axis needs to align with the work surface. Typical use cases include final-pass surface prep on metal, wood, and composite materials in shop or field environments. The compact overall length of 7 inches makes it practical for use in areas where a larger random-orbit or right-angle tool would not fit. It is commonly used in production finishing lines, body shops, and custom fabrication shops.

Installation Notes

Installation and operation of this tool should be performed by qualified technicians familiar with pneumatic tool safety practices. Before connecting to an air supply, verify that the air line pressure does not exceed the rated inlet pressure and that an inline filter-regulator-lubricator is installed to protect internal components. Always depressurize the air line before attaching or removing the tool. Follow applicable workplace safety standards and manufacturer guidelines for abrasive accessory selection and secure attachment before operation.
