SPEEDAIRE 21AA47 Impact Wrench
The SPEEDAIRE 21AA47 is a new air-powered impact wrench built for general-duty fastening work. It delivers 400 ft-lb of breakaway and fastening torque through a 1/4 in NPT female air inlet. The pistol-grip tool runs at a free speed of 11 000 RPM and produces 1 400 impacts per minute. It operates at 90 psi with a 20 cfm air consumption rate.
Suited for general bolting up to 3/8 in
This wrench suits technicians and mechanics who need reliable torque for bolts up to 3/8 in diameter. The three speed settings allow control across a range of tasks. It is not suited for explosive-environment work because it carries no such rating. Buyers who need a cordless electric tool or a higher torque ceiling should look at other product types.
Simple hook-up with 3/8 in hose minimum
Installation requires connecting a 3/8 in minimum hose to the 1/4 in NPT inlet and setting supply pressure between 50 psi and 90 psi. Bottom exhaust directs air away from the work area. The tool runs at 93 dB, so hearing protection is advisable. California Proposition 65 warnings note chemicals linked to cancer and reproductive harm.
