Keyseating is a type of machining process where the internal shapes & forms that make up a machine key are cut using a reciprocating, single-point cutting tool (like the shaping process). The keyseating cutter is secured in a holder by a clamp. It can move vertically within a tool guide when paired with a feed bar. Internal keyways and other straight-sided shapes and forms are generally cut by keyseating machines, also known as keyseaters, in non-production parts.

What are hex key stocks?

Hex key stocks, also called hex shaft stocks / hex stocks, are frequently used for transmission shafts, axles, machine mounts, drill bits, tool shafts and gearbox output shafts. Hex key stocks save money on machining expenses as they do not need a key or keyway to lock the shaft to a hub or gear.
