Keyway Machining for Gear and Sprocket Manufacturers

Making quality gears and sprockets is only half the battle—they still need a precise internal keyway to lock into place. That’s where we come in.

At Keyseaters.com, we specialize in internal keyway machining for gear manufacturers, power transmission shops, and OEMs. Whether you’re cutting carbon steel, stainless, or hardened alloy components, we deliver repeatable, high-tolerance keyways with fast turnaround and zero tooling investment.

Keyway Broaching for Food Augers

Built for Power Transmission Applications

Gears and sprockets are torque-critical components. A poorly machined keyway risks backlash, misalignment, or even complete failure in the field.

Our shop is optimized for:

  • Spur gears

  • Helical gears

  • Sprockets (all pitch sizes)

  • Pulleys and timing wheels

  • Internal drive hubs and couplings

We hit tight tolerances with zero taper, ensuring a clean engagement with mating shafts.

Better Than Broaching, Faster Than EDM

Why leading gear shops send their parts to us:

  • No broach tooling required

  • Ideal for short and mid-size production runs

  • Compatible with blind bores

  • Cuts hardened alloys with ease

  • Rush jobs and same-week delivery available
