I need to cut a very small T-slot (similar to those found on Sherline milling table). Having little knowledge of proper nomenclature, the main slot leading down to the "T" section is 1/4", depth to the bottom of the "T" is .185", dia. of the cutter should be around .408", and the cutter face (thickness of the cutter) should be ~.090".
I can't find a T-slot cutter close to that size. The main probelm is with the width of the cutter face. The thinnest face is 15/64" with a dia of 9/16". This is too large for my application.
I have found Woodruff cutters that approximate the size that would fit my application.
The material being used is aluminum. Can Woodruff cutters be used to cut a T-slot? What problems can I expect? Do you know of a place that I can purchase a real T-slot cutter that meets my requirments?
