Am wanting to counterbore M12 capscrews in 4140, a dozen holes. An M12 counterbore from Sutton is well over $200 so that's not an going to happen.
What options do people use?
Would a 20mm 2 flute HSS slot mill be suitable.
I have a Bridgeport style mill with ER32 collets and a drill press.
Although only they only go up to M10, does anyone have any experience with the durability of the H&F counterbore set.
