Ingersoll Rand 345MAX Pneumatic Angle Grinder | 0.88 HP | 12,000 RPM | 5/8" - 11 Thread | Rear Exhaust

Ingersoll Rand 345MAX Pneumatic Angle Grinder combines a 0.88 HP air motor with a 12,000 RPM free speed to support efficient grinding and finishing operations. Part of the Ingersoll Rand MAX Series, this pneumatic grinder accommodates 5-inch grinding wheels and features a 5/8"-11 threaded spindle for compatible abrasive accessories. Its internal governor regulates motor performance to help maintain operating speed under load, supporting consistent material removal when working on metal surfaces. The right-angle configuration makes the tool suitable for grinding welds, preparing metal edges, and removing unwanted material during fabrication, vehicle repair, and equipment maintenance.

The 345MAX features a lightweight composite housing with an enhanced grip design and an auxiliary handle for controlled two-handed operation. Weighing 3.37 lbs and measuring 9.6 inches in length, the grinder balances motor output with manageable tool weight for repeated grinding tasks. A built-in lubricating wick improves lubrication of the bevel and pinion gear set, helping protect the angle drive components during operation. The variable-speed lever allows operators to control speed and power delivery, while the rear exhaust directs discharged air away from the grinding area. Operating at 90 PSI, the tool requires a 1/4-inch NPTF air inlet and a recommended 3/8-inch air hose.
