Thread: Hex Blind Hole in Polyester Resin
25/10/2014 18:55:03

Is it necessary for the hex to be full depth or could the lower half or so be a hole of a diameter that is large enough to clear the points of the hex. I have cut 1/4 hex in aluminium to a depth 5/8 inch, with a home made rotary broaching chuck. I can't imagine that you material is particularly hard so you could concave the front of the broach to give a more aggressive cut. Best of luck
