1/4" maximum work diameter, 60° outside chamfering mill.
An outside chamfering mill breaks the edge on the end of a round part in one pass, square to the axis and the same all the way round. You size it by the work, not by the cut: this one fits over anything up to 1/4" diameter, and one tool covers every part size below that.
The cutting mouth opens to 5/16" with a 3/64" recess hole. The body is 1/2" diameter and 1" long, and it screws onto a 5/16-24 threaded shank, 5/16" deep.
High-speed steel, hardened for wear resistance. The grind is completely chatterless, and the tool can be resharpened many times — so it is bought once and kept, not consumed.
It needs a shank. This mill has no shank of its own — it threads onto a straight threaded shank. We stock 5/16-24 shanks in 1/4" shank, 3/8" shank, 1/2" shank.
