Composite Straight Die Grinder
The Ingersoll/Rand G1H200RG4 is a new air-powered straight die grinder built with a composite body for reduced weight during extended use. It delivers 0.4 hp at a maximum speed of 20,000 RPM and accepts 1/4 inch collets for standard accessories. A locking throttle lever on the barrel grip helps prevent accidental starts.
Air Supply Requirements
The tool connects via a 1/4 inch NPT female air inlet and requires a compressed air source capable of sustaining the rated speed under load. Performance will drop if the supply pressure or volume falls below what the motor demands at 20,000 RPM. Ensure your compressor and hose diameter can maintain adequate flow without excessive pressure loss at the inlet.
Compatibility Check
Verify that your air line uses a 1/4 inch NPT male fitting to match the tool inlet without adapters. Confirm the collet size matches the shank diameter of the burrs or mounted stones you intend to run. Buyers who need a right-angle head or a different collet capacity should look for an alternative model.

Questions about this item
Which collet size should I choose for this die grinder?
The tool comes with a fixed 1/4 in collet, so no alternative size is offered.
What does the 20,000 RPM rating mean in everyday use?
It allows fast material removal on metal and composite surfaces when supplied with adequate air flow.
How does the 1/4 in NPT female air inlet limit performance?
The inlet size caps the maximum air volume the tool can draw, which in turn limits sustained power output.
