Dynabrade 48503 Air Disc Sander 2 in 25000 Rpm 0.4 Hp

Product Description

The DYNABRADE 48503 is a pneumatic handheld disc sander designed for aggressive material removal and surface finishing in professional trade environments. Running at 25,000 RPM and powered by compressed air at 90 psi, this tool delivers consistent performance on a 2-inch disc pad. It draws 23 CFM of air flow and produces 0.4 hp of output power. The 1/4-inch inlet fitting connects to standard shop air lines. Exhaust exits from the rear of the tool, directing airflow away from the work surface and the operator. HVAC fabricators, pipefitters, metalworkers, and general contractors are the typical users.

The 48503 is suited for small-area grinding, deburring, and surface preparation tasks where a compact footprint is required. The 2-inch disc size makes it effective in tight spaces and contoured surfaces where larger disc sanders cannot reach. It is commonly used on metal, weld seams, and composite materials in both shop and field settings. The tool ships with a wrench included for disc changes and routine maintenance.

Installation Notes

Installation and operation should be performed by qualified trade personnel familiar with pneumatic tool safety practices. Before connecting to an air supply, verify the line pressure does not exceed 90 psi and that the air supply is equipped with a filter-regulator-lubricator unit appropriate for air-powered tools. Disconnect the air supply before changing discs or performing any maintenance. Follow OSHA and applicable workshop safety standards when operating high-speed abrasive tools.
