Ingersoll Rand G1A120RG4 G1 Series Air Angle Grinder | 0.4 HP | 12,000 RPM | 1/4" Collet | Rear Exhaust

For controlled deburring, contour grinding, and localized surface preparation where side-entry access improves tool placement, the Ingersoll Rand G1A120RG4 G1 Series Air Angle Grinder combines a 0.4 HP pneumatic motor with 12,000 RPM free speed and a 1/4-inch collet. The angle-head configuration positions compatible shank-mounted accessories for working along edges, around weld areas, inside recesses, and across contoured components where a straight die grinder may be harder to align.

The Ingersoll Rand G1A120RG4 secures carbide burrs, mounted points, and other compatible 1/4-inch shank accessories through its collet system. A collet grips the accessory shank directly, allowing tooling to be matched to the workpiece material, surface profile, and required finish. The 12,000 RPM configuration provides a lower-speed option within the G1 angle-grinder range, while the rear exhaust routes discharged air away from the immediate grinding area.

Type: Air Angle Grinder | Model: G1A120RG4 | Series: G1 Series | Configuration: Angle | Motor Power: 0.4 HP | Free Speed: 12,000 RPM | Collet Size: 1/4" | Exhaust: Rear

Features:

• 0.4 HP pneumatic motor provides power for deburring, contour grinding, weld cleanup, and localized surface-finishing work.
• 12,000 RPM free speed supports controlled abrasive action with compatible shank-mounted accessories.
• 1/4-inch collet accepts properly matched carbide burrs, mounted points, and other accessories with compatible shank dimensions.
• Angle-head configuration helps position the accessory against edges, recesses, weld areas, and contoured surfaces.
• Rear exhaust directs discharged air away from the immediate grinding interface and workpiece.
• Lower-speed configuration provides an option for accessories and applications that do not require the higher rotational speeds of other G1 Series grinders.
• Collet-mounted tooling can be selected according to the material, surface geometry, and desired finish.

Made in USA:

Applications:

• Metal fabrication — removing burrs, blending localized weld areas, and refining edges on fabricated parts and assemblies.
• Foundry and casting cleanup — removing flash, parting lines, and surface imperfections from compatible cast components.
• Industrial maintenance and MRO — cleaning machinery parts, preparing repair areas, and correcting localized surface damage.
• Automotive and equipment repair — finishing brackets, housings, joints, and components where angle-head access improves positioning.
• General manufacturing — performing repetitive contour finishing, edge cleanup, and localized material removal on production components.

FAQs:

• Q: What accessories fit the Ingersoll Rand G1A120RG4?
  A: Use properly rated accessories with a compatible 1/4-inch shank, such as suitable carbide burrs and mounted points. Confirm the accessory dimensions, workpiece compatibility, and maximum operating-speed rating before use.
• Q: What is the benefit of the angle-head configuration?
  A: The angle head provides side-entry access to edges, recesses, weld areas, and contoured surfaces that may be harder to approach with a straight horizontal grinder.
• Q: When should a 12,000 RPM grinder be selected?
  A: The lower-speed configuration can suit accessories, accessory diameters, materials, or finishing processes that call for reduced rotational speed. Always follow the accessory manufacturer's recommended operating range.
• Q: Can conventional grinding wheels be installed on this model?
  A: No. This tool uses a 1/4-inch collet for compatible shank-mounted accessories and is not configured with the threaded spindle and guard required for conventional grinding wheels.
• Q: What does rear exhaust mean?
  A: Rear exhaust routes discharged air toward the back of the grinder rather than around the collet and immediate work surface, helping reduce airflow disturbance near the grinding area.
