Ingersoll Rand G1H250FG4 Horizontal Grinder | 0.4 HP | 25,000 RPM | 1/4″ Collet | Front Exhaust

Description

For high-speed deburring, edge cleanup, and localized material removal with shank-mounted accessories, the Ingersoll Rand G1H250FG4 Horizontal Grinder combines a 0.4 HP pneumatic motor with 25,000 RPM free speed and a 1/4-inch collet. The horizontal configuration keeps the accessory aligned with the tool body for direct access to openings, edges, narrow surfaces, and fabricated components where a straight approach supports controlled grinding and finishing.The Ingersoll Rand G1H250FG4 uses its collet to grip compatible carbide burrs, mounted points, and other 1/4-inch shank accessories selected for the material and required finish. Its higher spindle speed favors smaller accessories designed for rapid cutting and surface conditioning, while the front exhaust directs discharged air toward the front of the tool. Buyers should consider exhaust direction when selecting the grinder for work around loose debris, dust, or surfaces where airflow at the work area may affect the process.Type: Horizontal Grinder | Model: G1H250FG4 | Series: G1 Series | Configuration: Horizontal | Motor Power: 0.4 HP | Free Speed: 25,000 RPM | Collet Size: 1/4″ | Exhaust: FrontFeatures:0.4 HP pneumatic motor provides power for high-speed deburring, grinding, and localized surface-finishing operations.25,000 RPM free speed supports productive 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.Horizontal configuration provides straight-line accessory alignment for working on edges, openings, grooves, and accessible internal surfaces.Front exhaust directs discharged air toward the front of the grinder and should be considered when positioning the tool around debris and the workpiece.Collet-mounted configuration allows accessory selection according to the workpiece material, surface profile, and required finish.G1 Series speed-and-power combination supports repetitive grinding and deburring with smaller mounted accessories.Made in USA: Applications:Metal fabrication deburring cut edges, cleaning openings, and removing localized material from fabricated components.Foundry and casting cleanup removing flash, parting lines, and small surface imperfections with compatible carbide burrs or mounted abrasives.Industrial maintenance and MRO cleaning machinery parts, refining repair areas, and preparing localized surfaces during equipment service.Automotive and transportation repair finishing brackets, housings, ports, and components where straight-line accessory access is practical.General manufacturing performing repetitive edge finishing, deburring, and localized grinding on production parts.FAQs:Q: What accessories fit the Ingersoll Rand G1H250FG4?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 does the 25,000 RPM specification mean?A: It is the grinder’s free speed, meaning rotational speed without load. Actual working speed can vary with the accessory, applied pressure, workpiece material, and available compressed-air supply.Q: How does the 0.4 HP G1H250FG4 differ from higher-powered G3 Series grinders?A: The G1H250FG4 combines a 0.4 HP motor with higher 25,000 RPM speed for compatible smaller mounted accessories, while the supplied G3 configurations use higher-power 1.35 HP motors at lower speeds. Tool selection should be based on accessory size, material-removal requirements, access, and the workpiece.Q: Can conventional grinding wheels be installed on this model?A: This grinder uses a 1/4-inch collet for compatible shank-mounted accessories. Do not install threaded-spindle grinding wheels or accessories that are not intended for the tool’s collet configuration.Q: What should be considered with the front exhaust configuration?A: Front exhaust directs discharged air toward the accessory end of the tool. Position the grinder and workpiece so exhaust airflow does not unnecessarily disturb loose debris or direct contaminants toward the operator or surrounding personnel. .variation-details { width: 100%;
