Dynabrade 53235 Air Angle Grinder 7 in 8500 Rpm 2 Hp

Product Description

The DYNABRADE 53235 is a pneumatic angle grinder built for heavy-duty material removal, grinding, and surface preparation in industrial and fabrication environments. It accepts a 7-inch wheel and spins at 8,500 RPM, driven by a 2 HP air motor that draws 84 CFM at a 1/2-inch NPT inlet. The 5/8-11 spindle is the standard thread for 7-inch Type 27 and Type 28 grinding and flap discs. Rear exhaust directs spent air away from the work surface, reducing debris interference. This tool is suited for licensed tradespeople, welders, and industrial maintenance technicians working in fabrication shops, structural steel applications, and heavy manufacturing settings.

The 53235 is designed for stationary and portable use wherever a large-diameter angle grinder is required. Typical applications include weld seam grinding, casting cleanup, heavy stock removal on ferrous and non-ferrous metals, and surface conditioning prior to coating or inspection. The 1/2-inch air inlet makes it compatible with standard shop air systems running adequate CFM and pressure for sustained use. Its rear exhaust configuration is especially practical in confined spaces or overhead work where forward exhaust would direct air and debris toward the operator.

Key Features

• 7-inch wheel diameter accepts standard Type 27 and Type 28 grinding discs
• 8,500 RPM free speed for aggressive material removal
• 2 HP pneumatic motor delivers consistent power under load
• 5/8-11 spindle thread — industry-standard for large-diameter abrasive wheels
• Rear exhaust routing keeps work area cleaner and reduces operator debris exposure
• 1/2-inch NPT air inlet compatible with standard industrial air supply lines

Compatibility

Designed for use with 7-inch abrasive grinding wheels and flap discs featuring a 5/8-11 arbor thread, consistent with standard industrial angle grinder accessory sizing.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety and applicable OSHA abrasive wheel standards. Before mounting or changing a wheel, disconnect the air supply and verify the tool is fully depressurized. Ensure the air supply CFM rating meets or exceeds the 84 CFM requirement to prevent power loss under load. Always inspect the abrasive wheel for cracks or damage before mounting, and use the appropriate guard as required by ANSI B7.1 and OSHA 1910.243.
