Keyway Cutting Services for Precision Internal Keyways
Looking for expert keyway cutting services? At Keyseaters.com, we specialize in precision internal keyway machining using heavy-duty vertical keyseating machines. Whether you’re working with gears, pulleys, or shafts—we deliver clean, accurate keyways that meet tight tolerances and fast lead times.
We work with all common metals—including stainless steel, hardened alloys, aluminum, and more—and serve manufacturers across the U.S. with high-mix, low-volume and recurring production runs.
Why Choose Keyseating for Internal Keyways?
Keyseating is the ideal method for cutting internal keyways in components where broaching or wire EDM falls short. Here’s why:
Better for hard metals: Handles materials like 17-4 stainless and tool steels with ease
No need for thru-holes: Perfect for blind keyways and enclosed components
High precision: Clean internal profiles, tight tolerances
Low tooling cost: Efficient for one-off and small batch production
If your part requires accuracy and strength, keyseating is often the best solution.
