For high-speed deburring, contour grinding, and localized surface preparation where side-entry access improves tool positioning, the Ingersoll Rand G1A200FG4 G1 Series Angle Grinder combines a 0.4 HP pneumatic motor with 20,000 RPM free speed and a 1/4-inch collet. The angle configuration positions compatible shank-mounted accessories for controlled contact with edges, recesses, weld areas, and fabricated components that may be awkward to approach with a horizontal grinder.
The Ingersoll Rand G1A200FG4 uses its collet to secure compatible carbide burrs, mounted points, and other 1/4-inch shank accessories selected for the material and required finish. Its front exhaust directs discharged air toward the accessory end of the tool, making grinder orientation important when working around loose debris and contaminants. The combination of 20,000 RPM speed, angle-head access, and collet-mounted tooling supports repetitive finishing work in fabrication, casting cleanup, equipment repair, and general manufacturing.
Type: Angle Grinder | Model: G1A200FG4 | Series: G1 Series | Configuration: Angle | Motor Power: 0.4 HP | Free Speed: 20,000 RPM | Collet Size: 1/4" | Exhaust: Front
Features:
- 0.4 HP pneumatic motor supplies power for deburring, localized grinding, edge finishing, and surface-preparation operations.
- 20,000 RPM free speed supports material removal with compatible shank-mounted accessories rated for the tool's operating speed.
- 1/4-inch collet accepts properly matched carbide burrs, mounted points, and other accessories with compatible shank dimensions.
- Angle-head configuration supports side-entry access to edges, recesses, weld areas, and surfaces that may be difficult 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.
- Collet-mounted accessory system allows tooling to be selected according to the workpiece material, geometry, and required surface finish.
- G1 Series configuration provides a focused combination of pneumatic power, accessory speed, and angle-head maneuverability for repeated finishing work.
Made in USA: 
Applications:
- Metal fabrication — deburring cut edges, blending localized weld areas, and cleaning fabricated parts with compatible mounted accessories.
- 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 refining localized surfaces during equipment service.
- Automotive and transportation repair — finishing brackets, housings, joints, and components where angle-head access improves accessory positioning.
- General manufacturing — performing repetitive edge finishing, deburring, and localized material removal on production components.
FAQs:
- Q: What accessories can be used with the Ingersoll Rand G1A200FG4?
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: What is the advantage of the angle configuration?
A: The angle head positions the accessory for side-entry access to edges, recesses, weld areas, and 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 does the 20,000 RPM specification mean?
A: It is the grinder's free speed, meaning rotational speed without load. Actual working speed varies with accessory selection, applied pressure, workpiece material, and the available compressed-air supply. - Q: What should be considered with the front exhaust configuration?
A: Front exhaust directs discharged air toward the accessory end of the grinder. Position the tool and workpiece so exhaust airflow does not unnecessarily disturb loose debris or direct contaminants toward the operator or nearby personnel.
