The company is now offering a complete set of high speed steel broaches, guide bushings and necessary shims for cutting 1/8", 3/16", 1/4" and 3/8" keyways in 36 keyway combinations. In addition to its four broaches, the No. 10-10A combination set includes 18 bushings with diameters increasing in 1/16" increments from 1/2" to 1 9/16". The Minute Man No. 10-10A set will handle a wide range of keyway cutting in machine maintenance or parts production work.
The complete broach set is furnished in a varnished hardwood box and is available off-the-shelf through local industrial distributors. The broaches supplied are high speed steel, push-type broaches and can be used with any hydraulic press with adequate throat depth. They require no special skill or setup time.
Other keyway broach sets, also available from stock, contain smaller or larger broaches and bushings and extend the range of keyway sizes that can be cut from 1/16" to 3/4" keyways in bores from 1/4" to 3" bore diameter.
