Ingersoll Rand 3107G Air Die Grinder 27000 Rpm 1/4 Inch

Product Description

The INGERSOLL RAND 3107G is a heavy-duty air die grinder from the Edge Series, designed for grinding, deburring, and surface preparation in demanding trade and industrial environments. It runs at a free speed of 27,000 RPM and accepts a 1/4-inch collet, making it compatible with a wide range of mounted grinding bits, carbide burrs, and abrasive stones. The composite housing keeps weight low while maintaining durability under continuous use. Ball bearing construction supports the spindle for extended service life. Rear exhaust directs air away from the work surface, improving visibility and reducing debris blowback during precision work.

The 3107G is suited for metal fabrication shops, HVAC duct work, pipefitting, and general mechanical service where tight clearances or finish work require a compact rotary tool. Its 1/4-inch collet is the industry-standard size for die grinder accessories, giving technicians access to a broad selection of tooling. The 1/3 self-locking throttle reduces operator fatigue during extended use and helps maintain consistent speed without constant trigger pressure. This grinder is a fit for both production environments and field service applications.

Key Features

• 27,000 free speed RPM for fast material removal and finish grinding
• 1/4-inch collet accepts standard die grinder bits, burrs, and stones
• Durable composite housing reduces overall tool weight
• Ball bearing construction for extended spindle life under load
• Rear exhaust directs spent air away from the work area
• 1/3 self-locking throttle for reduced hand fatigue during prolonged use

Compatibility

Designed as a heavy-duty pneumatic die grinder accepting standard 1/4-inch shank rotary tooling; compatible with any regulated compressed air supply meeting the tool's inlet requirements.

Installation Notes

Installation and operation should be performed by a qualified technician familiar with pneumatic tooling. Before connecting to an air supply, verify the line pressure matches the tool's rated operating range and ensure an inline air filter and lubricator are present to protect internal components. Never exceed the rated free speed when selecting grinding accessories, as abrasive wheels and mounted points carry their own maximum RPM ratings that must meet or exceed the tool speed. Disconnect the air supply before changing collet tooling.
