Right-Angle Die Grinder for Industrial Finishing
This new Ingersoll/Rand G1A120RG4 is a composite-bodied right-angle die grinder built for light material removal, deburring, cleaning rough castings and weld cleanup. Its ergonomic D-shaped grip and patent-pending soft-mount system reduce vibration to limit operator fatigue during extended use in shipbuilding, heavy machinery, oil and gas or aerospace environments.
Suited for Detail Finishing Not Heavy Stock Removal
The tool suits technicians who need a manoeuvrable grinder for intricate finishing tasks in tight corners where a straight grinder cannot reach. It is not for operators who require high-torque material hogging or sustained heavy-duty cutting because the 0.4 hp motor is sized for precision work rather than aggressive stock removal.
0.4 hp Motor Defines the Application Envelope
The 0.4 hp rating is the single specification that decides whether this grinder matches the job; it delivers enough speed for light finishing and deburring but lacks the power for rapid grinding of thick welds or hard metals. Buyers must match that output to the intended task to avoid overloading the motor.

Questions about this item
How much vibration and heat does the 0.4 hp motor produce during extended use?
The patent-pending soft-mount system cuts vibration to protect the motor and switch, while the composite body stays cool during long finishing jobs.
What air supply and fittings are required to run the 1/4 in NPT female inlet?
You need a compressed-air line that delivers 120 psi at the tool, plus a matching 1/4 in NPT male quick-connect and suitable hose.
Will this die grinder accept the collets and accessories I already use on my older straight grinders?
The right-angle head uses the same 1/4 in collet standard, so existing carbide burrs, mounted points and sanding discs fit directly.
