Any one know where to buy a 7/16 or 11 mm 60 degree dovetail cutter. I have searched all over the internet and can’t find one. Cutting several dovetails for air rifle front globe sight in aluminum bar stock. This is for the 4-h shooting club.

I don't know why you couldn't make cut one with a straight end mill...cut two and three with any 60 deg cutter you have. Be sure and calculate your proper depth before you start.

MSC or McMaster-Carr should have what you're looking for.

Basically I made two offset cuts. Had a dozen to do..
