Dynabrade 48337 Angle Air Die Grinder 0.4 Hp 30000 Rpm

Product Description

The DYNABRADE 48337 is a 7-degree offset angle air die grinder built for precision grinding, deburring, and surface finishing in demanding trade and industrial environments. Powered by compressed air at 90 psi, it delivers up to 30,000 RPM through a 1/4-inch collet (6 mm), giving technicians the rotational speed needed for fine metalwork and hard-to-reach angles. The lever-style throttle provides controlled operation, and the rear exhaust directs airflow away from the work surface. At 1 pound, this grinder is lightweight enough for extended overhead or confined-space use. It is typically installed and operated by industrial maintenance techs, fabricators, and HVAC sheet metal workers.

The 48337 suits applications where a straight die grinder cannot reach due to geometry constraints. The 7-degree offset head angle makes it well suited for weld cleanup, port work, and finish grinding on metal components in tight assemblies. It requires a clean, dry compressed air supply at 90 psi and consumes approximately 26 CFM at full load, so an adequately sized compressor and supply line are necessary for sustained use. The lever throttle allows precise speed modulation during delicate finishing passes.

Key Features

• 7-degree offset die grinder head for access in restricted work areas
• 30,000 RPM free speed for high-efficiency material removal and finishing
• Lever-style throttle for variable speed control during operation
• Rear exhaust keeps airflow directed away from the workpiece and operator
• Lightweight at 1 pound, reducing fatigue during extended use
• CE Certified and EAC Certified for compliance in applicable markets

Compatibility

Designed for use with standard 1/4-inch (6 mm) rotary die grinder accessories including mounted points, carbide burrs, and small grinding wheels rated for 30,000 RPM or higher. Requires a compressed air supply at 90 psi with sufficient volume to sustain 26 CFM demand.

Installation Notes

A licensed or qualified pneumatic tool technician should verify that the shop air system can sustain the required 26 CFM at 90 psi before connecting this tool. Always depressurize the air line before attaching or removing the grinder from the supply hose. Inspect the collet and accessory shank for wear or damage before each use, and confirm that all mounted accessories are rated for at least 30,000 RPM. Follow applicable OSHA and ANSI B11 safety standards for abrasive tool operation.
