Benchdog chamfer tool

a tool to chamfer your dog holes. 

It uses a 12x12x2.2mm carbide insert to cut 1mm chamfers into the dog holes

its also got a hole for 2 15x3mm magnets to pull out magnetic doghole covers like the ones here: https://www.printables.com/model/1149681-magnetic-benchdog-hole-covers

I'm using the inserts here:
