Keyway Machining for Mining and Heavy Equipment Manufacturers

When your equipment moves earth, hauls payloads, or operates in brutal conditions, failure isn’t an option. That’s why OEMs and rebuilders across the mining and heavy equipment sectors trust Keyseaters.com for internal keyway machining that holds up under pressure.

We cut keyways in heavy, hardened, and oversized parts—no broach tooling required. Just clean, accurate internal slots delivered fast.

Keyway Broaching for Food Augers

Keyways Built for Extreme Torque and Load

Your parts power:

  • Dozers

  • Crushers

  • Hydraulic drives

  • Conveyors

  • Mining trucks

  • Drilling rigs

  • Loaders and graders

And every shaft, hub, coupling, or gear in those systems relies on a keyway to hold torque and stay aligned.

We cut keyways that don’t slip, round out, or taper under stress.

We Work with OEMs, Rebuilders & Job Shops

  • Heavy equipment manufacturers

  • Mining fleet rebuilders

  • Hydraulic drive system builders

  • Power transmission suppliers

  • Repair shops handling oversized parts

Short runs, one-offs, or contract work—we can handle it. And we’re used to parts weighing hundreds of pounds.
