Polygon Solution’s 9/16" Hex 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.
PRE-DRILL SIZE
The Recommended Pilot Hole Diameter for a 1/2″ Hex is: .585″
The Recommended Minimum 45° Chamfer for a 1/4″ Hex is: .659″
