You know that tool you screw on the axle and hammer to get the axle out of the bearing?
This is it's opposite, it pulls the axle back into the bearing.
Concur with brwrench, never seen one of these adv as a T or A tool, given the way T axle is setup it wouldn't be usefull anyhow, dunno how the A's are setup tho.
Nice rugged looking only function counts tool : )
