SKU CH-6589-JT10S

Right-angle pneumatic file delivers 5,000 strokes per minute with a 1/4-inch stroke, consuming 18 CFM at 90 psi

  • Delivers 5000 strokes per minute for rapid material removal
  • 2 hp motor provides consistent power in a compact design
  • 1/4 in stroke length enables precise control on detailed work
  • 0 CFM at full load ensures steady pneumatic performance
  • Composite housing reduces weight while maintaining durability

Right-Angle Air File for Tight Spaces

The Dynabrade 12250 RA Air File is a pneumatic tool designed for metal finishing in confined areas. Its right-angle configuration allows access where straight files cannot reach. Technicians working on automotive bodywork or industrial fabrication will find it suited for detailed material removal tasks.

Sustained Operation at Rated Pressure

At 90 psi the tool delivers 5000 strokes per minute with a 1/4 inch stroke length while consuming 18.0 CFM at full load. The lever throttle provides direct speed control during extended use. A built-in air flow regulator helps maintain consistent performance, and the composite housing reduces vibration transmitted to the operator during long sessions.

Upgrade from Hand Filing or Larger Tools

This air file replaces manual hand filing for faster, more uniform results on edges and corners. It also serves as a compact alternative to bulkier pneumatic grinders when workspace is limited. The jump is worthwhile for shops that regularly need precise, powered filing in restricted access points and have a compressor capable of supplying the required airflow.

Questions about this item

How much air does the Dynabrade 12250 RA Air File consume when running continuously at full load?

It draws 18.0 CFM at full load and requires a steady 90 psi supply to maintain its 5000 SPM stroke rate throughout the day.

What existing air-line fittings and hose must I already have to connect this 1/4 in NPT inlet tool?

You need a 1/4 in NPT coupler on your supply line and a minimum 3/8 in inside-diameter hose to deliver the required 18.0 CFM without excessive pressure drop.

Will the 1/4 inch stroke length and right-angle composite housing fit the same workspaces as my older straight pneumatic files?

The 6 5/8 in overall length and right-angle composite housing let it reach tight corners where straight files cannot, while the 1/4 in stroke matches standard finishing work.
