An interesting tool for an unknown (presumably light duty finishing) purpose, it may have have an RAAF or DoD background.
MT3 shank 2 1/8" dia x 3" long body, the included angle measures at between 8.5° to 9° so maybe 13.2 taper per side. There has been an amateurish attempt to use it judging by the spin marks and divot on the shank but the flutes are sharp and undamaged.
Pick up at Laidley 4341 or pay for postage, weight is 1.2kg so a 3kg Australia Post satchel will do the trick.
