Ingersoll Rand G1A120FG4 G1 Series Angle Grinder | 0.4 HP | 12,000 RPM | 1/4" Collet | Front Exhaust

For controlled deburring, contour finishing, and localized material removal with angle-head access, the Ingersoll Rand G1A120FG4 G1 Series Angle Grinder combines a 0.4 HP pneumatic motor with 12,000 RPM free speed and a 1/4-inch collet. The angle configuration positions compatible shank-mounted accessories for working on edges, recesses, weld areas, and contoured components where approaching the surface from the side can improve tool placement and operator control.

The Ingersoll Rand G1A120FG4 secures compatible carbide burrs, mounted points, and other 1/4-inch shank accessories through its collet system. Compared with higher-speed G1 angle grinder configurations, its 12,000 RPM free speed provides a lower-speed option for accessories and applications that require a different rotational-speed range. The front exhaust directs discharged air toward the accessory end of the tool, so grinder orientation and airflow should be considered when working around loose debris and contaminants.

Type: Angle Grinder | Model: G1A120FG4 | Series: G1 Series | Configuration: Angle | Motor Power: 0.4 HP | Free Speed: 12,000 RPM | Collet Size: 1/4" | Exhaust: Front

Features:

• 0.4 HP pneumatic motor supplies power for deburring, contour grinding, edge finishing, and localized surface-preparation work.
• 12,000 RPM free speed supports compatible shank-mounted accessories selected for the material, application, and required finish.
• 1/4-inch collet accepts properly matched carbide burrs, mounted points, and other accessories with compatible shank dimensions.
• Angle-head configuration supports accessory positioning on edges, recesses, contoured surfaces, and weld areas that may be awkward to approach with a horizontal grinder.
• Front exhaust directs discharged air toward the accessory end of the tool and should be considered when positioning the grinder around debris and the workpiece.
• Lower-speed configuration provides an alternative to faster G1 angle grinders when the selected accessory or finishing process calls for reduced rotational speed.
• Collet-mounted accessory system allows tooling to be selected according to workpiece material, geometry, and surface-preparation requirements.

Made in USA:

Applications:

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

FAQs:

• Q: What accessories can be used with the Ingersoll Rand G1A120FG4?
  A: Use compatible accessories with a 1/4-inch shank, such as properly rated carbide burrs and mounted points. Confirm the accessory dimensions, material suitability, and maximum operating-speed rating before use.
• Q: When would the 12,000 RPM configuration be selected instead of a faster G1 angle grinder?
  A: The 12,000 RPM configuration can be selected when the chosen accessory, accessory diameter, workpiece material, or finishing process calls for lower rotational speed. Always follow the accessory manufacturer's recommended operating-speed range.
• 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 difficult to reach or control with a straight horizontal grinder.
• Q: Can conventional grinding wheels be installed on this model?
  A: No. This grinder uses a 1/4-inch collet for compatible shank-mounted accessories and is not configured with a threaded spindle and guard for conventional grinding wheels.
• Q: What should operators consider with the front exhaust?
  A: Front exhaust directs discharged air toward the accessory end of the grinder. Position the tool and workpiece so airflow does not unnecessarily disturb loose debris or direct contaminants toward the operator or nearby personnel.
