|Broach gauges can be used to make sure that the size of the hexagon
or square hole has been machined properly. Broach gauges are held to
Polygons broach gauges are made as GO and NO/GO pairs. Each gauge (or Gage) is designed to be held by hand and inserted into the hexagon or
square hole. If the NO/GO gauge fits, then the hole is too large and the
part fails inspection. If the GO gauge fits, then the hole is the right
size and the part will pass inspection. If the hole was too small the GO
gauge would not have fit inside. Gauges also can help to determine of
there is too much twist in the form, a common feature of holes
manufactured using the rotary broaching process.
Broach gauges are made of durable hardened M-2 tool steel. Broach
gauges have no taper, and are made to custom shapes and sizes. For more
