Chicago Pneumatic CP3030-418R Angle Die Grinder

SKU CH-YBNA-P18DC

A right-angle air die grinder delivering 18,000 RPM free speed with 0.54 hp for industrial grinding and finishing tasks

  • 18,000 RPM free speed for rapid material removal
  • 54 hp motor delivers strong torque in a compact body
  • Gearless design reduces vibration and extends tool life
  • Aluminium handle with composite cover stays cool during extended use
  • Rear exhaust directs air away from the workpiece

Right-Angle Die Grinder for Industrial Finishing

The Chicago Pneumatic CP3030-418R is a compact air die grinder built for metal fabrication, weld blending and deburring in tight spaces. Its gearless right-angle head and lightweight aluminium housing with a composite cover reduce operator fatigue during extended use. Variable-speed control via the throttle lever allows precise material removal on ferrous and non-ferrous workpieces. Industrial-grade ball bearings support continuous production demands.

1/4-Inch NPT Air Inlet and 90 psi Requirement

Connection to the supply line uses a 1/4 in NPT female inlet with a minimum 3/8 in hose to deliver the required 90 psi. At full load the tool draws 21.0 CFM, while a typical 15-second run averages 5.25 CFM. Verify that the compressor and piping can sustain this flow before installation. An undersized supply will cause pressure drop and speed loss under load.

Sustained Output at 18,000 RPM Free Speed

The 0.54 hp motor maintains 18,000 rpm free speed when the air supply meets the 21.0 CFM demand at 90 psi. Rear exhaust directs air away from the work surface during long grinding passes. Gearless construction eliminates gear-mesh heat buildup, so power delivery stays consistent over repeated cycles. Included wrenches simplify collet changes for minimal downtime between tasks.

Questions about this item

What does 18,000 RPM free speed mean when the grinder is under load?

Free speed is the no-load maximum; under load the speed drops and actual material removal depends on the 0.54 hp motor and the 21.0 CFM air supply at 90 psi.

How does the 1/4 in NPT air inlet and 3/8 in minimum hose size limit airflow?

The 1/4 in NPT inlet and 3/8 in hose must deliver 21.0 CFM at 90 psi; undersized hose or fittings will restrict flow and reduce the 0.54 hp output.

What clearance is needed for the right-angle head and overall length?

The right-angle head measures 4 7/16 in and the overall length is 6 7/8 in, so the work area must accommodate those dimensions for the collet to reach the workpiece.
