Polygon Solution’s 7/64″ Square Rotary Broach cutting tools are designed for superior performance when machining aluminum, brass, and mild steel. Polygon recommends drilling the pilot hole 3% oversize for hexagon forms. Pilot holes should also include a 45° chamfer and extra depth for chip accumulation. Expect reduced tool life when broaching tougher materials and tighter pilot holes.
