Rotary Broach Custom Options

hex-broach-custom-across-the-flats
Our Hex Rotary Broaches can be ordered in custom dimensions. Can’t find the size you’re looking for? Polygon Solutions provides fast delivery on custom ½” or 8mm shank hexagon rotary broaches. Simply specify the desired across flat dimension when ordering. Polygon’s manufacturing tolerance is +0/-.0005”. For example, a custom hex broach with 0.1234” across flat dimension is part number H01234B.
Hex Rotary Broach Custom Broaching Depth
If you need a hex rotary broach to cut deeper than our standard dimensions, perhaps to clear a counter-bore, you can request a custom cut length. Custom cut lengths may be limited by the back-taper on the side of the hex broach, or manufacturing limitations. Please call (239) 628-4800 for more information. Rotary broaching more than 1-2x the across flat dimension may not be successful. Broaches may also be weakened because of a deeper cut length.
Hex Rotary Broach Custom Rake Angle
If you need a hex rotary broach to cut deeper than our standard dimensions, perhaps to clear a counter-bore, you can request a custom cut length. Custom cut lengths may be limited by the back-taper on the side of the hex broach, or manufacturing limitations. Please call (239) 628-4800 for more information. Rotary broaching more than 1-2x the across flat dimension may not be successful. Broaches may also be weakened because of a deeper cut length.
Single vent holes are standard with hex rotary broach forms larger than .079″ and allow air and/or fluid to pass though the hex broach and reduce any hydraulic pressure that may occur when broaching a blind hole. Polygon’s rotary broach tool holder is also designed with this feature. However, an additional cross vent hole can be added for holders without the pressure relief system.
Hex Rotary Broach Custom Dimensions
All of Polygon Solution’s hexagon rotary broaches are manufactured with a +0/-.0005” tolerance. However, hex broaches can be manufactured to a tighter +0/-.0004” tolerance. If you want to use the broach as a gauge, the hex broach can also be manufactured without a back-taper. For more information, see Rotary Broach Gauges.
Custom Corner Radius
If you part allows for a corner radius, we can add a spun ground diameter to the hex broach to remove the sharp corners. The spun ground diameter is useful for reducing the chip size and pressure required for long tool life and successful rotary broaching operations.
