    Default Broach for AR15 Mag well needed

    I don't have the exact size needed yet (plans are all at the shop) so Iam inquiring about a general price for a broach. It will be about 3/4" wide x 3" long. It will have to cut four corners that have about 1/4" radius and make it nearly square, down to about a 1/32" radius. The material is 7075 ALuminum and the depth of the area to be broached is about 3". It is a through hole. I want to mount the part in a fixture on an arbor press and use the press to drive the broach through the hole. If all four corners at once would be to expensive or a problem we could do two, then flip the part, shim the broach and push it again for the other two.

    Any assistance is welcome.

    Jim, do you have drawings for your broach? or just for the part?
    Thanks
