Straight die grinder for precision metalwork
The Ingersoll/Rand G1H350RG4 is a 0.4 hp air-powered straight die grinder built for heavy-duty material removal. Its composite barrel grip reduces vibration during extended use. A locking throttle lever on the top switch prevents accidental starts. The tool runs at 35000 RPM for fast cutting, grinding and polishing.
Upgrade from lower-speed rotary tools
This grinder replaces slower electric rotary tools when consistent high speed and uninterrupted run time are required. The jump is worth it for shops that need sustained 35000 RPM performance without motor overheating. Air power delivers constant torque through long sessions. The heavy-duty rating suits daily industrial workloads.
Fits standard 1/4 in air systems
The 1/4 in NPT female air inlet connects directly to common shop compressor lines. A 1/4 in collet accepts standard carbide burrs and mounted points. Two collet wrenches are included for quick accessory changes. The bare-tool kit assumes the operator already supplies compressed air and lubrication. California Proposition 65 warnings apply.

Questions about this item
What air inlet size and thread does the G1H350RG4 require?
The tool connects to a 1/4 in NPT female air inlet, so your hose or fitting must match that thread.
How do you install the collet and which step is often missed?
Use the two supplied collet wrenches to tighten the 1/4 in collet securely; forgetting to hold the spindle while tightening is the common error.
What routine maintenance will this air grinder need?
Add a few drops of pneumatic tool oil into the air inlet before each use and drain moisture from the compressor tank daily to prevent internal corrosion.
