Anyway, a quick search indicates that 5/16" (0.3135" finished dimension) hex broaches are available from popular distributors MSC Direct and McMaster-Carr at about one-third the price of an 8mm (0.3154" finished dimension) hex broach. About $130 for 5/16" vs. about $400 for 8mm.

What is the actual size of REV's 8mm hex shaft? Will 5/16" work?
Aluminum 8mm hex shaft on MMC has a tolerance of +/- .23mm. That would be .3059in - .3240in. Steel 8mm hex has a tolerance of -0.05mm. Thus 8 - 7.95mm or in inches that's .315 - .313.
