Thread: Gunsmithing advice re HSS milling bits

Can anyone tell me if you are able to grind HSS milling bits to change their length or profile ?

I'm wanting a 3/8th 60 degree HSS dovetail cutter for opening up an existing front sight dovetail to take a larger 3/8th sight base.
Closest thing I can find is this 10mm one

Wondering if you could grind a little off the bottom then the shoulder width would come in a little from 10mm to 3/8th"

Or even better would there be someone out there that actually has a 3/8th dovetail cutter mill ?
And no Robbie at Gunworks doesn't have one as nice little things like that just get wrecked in a working gunsmiths shop.

Cheers
