Keyway Broach Sets

Minute Man broach sets will cut any standard keyway in about 1 minute. To cut a keyway using this method, The duMont Corporation suggests placing a bushing in the bore of a pulley, gear, collar or similar workpiece; then slip a broach of the right keyway size in the slot in the bushing, and press the broach through with an arbor press of the type found in any shop. The total time is about 1 minute compared to almost an hour for setting up a shaper to do the same job.
