SPEEDAIRE 21AA88 0.5 hp Die Grinder
The SPEEDAIRE 21AA88 is a straight die grinder rated at 0.5 hp with a maximum speed of 22000 RPM. It features a 1/4 in NPT female air inlet and a 1/4 in collet for accessory mounting. The barrel grip design and included safety throttle lever with lock-off switch support controlled operation on ceramic, steel and wood.
Medium-duty straight grinder for metal and woodwork
This tool suits technicians and fabricators performing medium-duty grinding, deburring or finishing tasks using a straight-line air tool. Buyers who need an angled head for tight access, a larger collet capacity or a kit with mounted abrasives included should look at alternative configurations.
1/4 in collet size determines accessory fit
The 1/4 in collet accepts only accessories with matching shank diameters, so users must verify their bits and burrs match this dimension. The 1/4 in NPT female inlet requires a compatible hose fitting to supply compressed air for operation.
