Aerospace-Grade Keyway Machining for Flight-Critical Components

Precision isn’t a luxury in aerospace—it’s a mandate. At Keyseaters.com, we specialize in high-accuracy internal keyway machining for aerospace and defense suppliers who demand nothing less than flawless execution.

From titanium couplings to stainless actuators and critical gear assemblies, we cut keyways to spec, hold tight tolerances, and deliver fast—so your supply chain stays lean and compliant.

Keyway Broaching for Food Augers

Trusted by Tier 1 & Tier 2 Aerospace Suppliers

Whether you’re building for:

  • Flight control systems

  • Power transmission in aircraft

  • Satellite components

  • UAV or defense robotics

  • Ground support vehicles

  • Military-grade pumps and valves

We help you meet demanding specs and timelines without broaching tooling or costly EDM setups.

Precision Machining for Critical Parts

Common aerospace and defense components we cut keyways into:

  • Shaft couplings and adapters

  • Precision gears

  • Servo motor components

  • Actuator hubs

  • Transmission parts

  • Weapon mount hardware

All machined in-house with direct oversight and rigorous inspection.
