SPEEDAIRE 21AA86 Straight Die Grinder
The SPEEDAIRE 21AA86 is a medium-duty straight die grinder built for metalworking, woodworking and ceramic finishing. It suits technicians and fabricators who need a compact air tool for precision grinding, deburring and polishing tasks.
0.5 hp motor with 22000 RPM maximum speed
The 0.5 hp motor delivers a maximum free speed of 22000 RPM, providing strong material removal on steel, wood and ceramic. The medium-duty rating means sustained high-load work will require pauses to maintain performance and tool life.

Questions about this item
Will the 1/4 in NPT female air inlet connect directly to the hose on my older compressor?
The grinder has a 1/4 in NPT female air inlet, so it accepts standard 1/4 in NPT male fittings. If your hose ends in the same thread, it connects without an adapter. Otherwise add the correct NPT coupler.
How can I confirm the grinder reaches 22000 RPM after installation?
The tool is rated for 22000 RPM max speed. Under normal shop pressure the throttle lever should spin the collet freely and the exhaust note will sound steady; a handheld tachometer on the collet nut gives a direct reading.
Does the box include the 1/4 in collet and the two spanner wrenches, or must I buy them separately?
The kit contents list the bare tool, a 1/4 in collet and two spanner wrenches. A case is also included. No additional accessories are required to start grinding.
