Here are the specifications (its a cheap electric version, but I ONLY need it for removing and installing blades): Wrench length: 11 5/8" Powerful 7 amp, 120V motor 2100 RPM, 2400 BPM 235 pounds of torque The socket size is 1/2" (pretty standard from what I have seen). Those are about the same numbers for torque I see on a lot of air impact wrenches of similiar value. I know it won't be as good, but I'm on a budget! Thanks y'all for any advice! And again, I know electric isn't as good, but should this get the blades off and on?
