Keyway MachiningPFI provides custom keyseating services, has decades of experience in the processes and has cut thousands of internal keyways. We have more than one hundred bore and keyway combinations in both US and metric sizes.

PFI has the keyseating capability to cut through hole and blind hole keyways including blind keyways with a groove or radius at the end.

PFI’s Mitts and Merrill keyseater can handle almost any bore and keyway combinations that you may need up to 3.5″ (63.5mm) wide through a 30″ long part.

PFI is able to cut shallow keyways, slightly deeper keyways, special widths, and keyways with a radius on the corners to prevent stress cracks. PFI can also custom broach specialized keyways such as but not limited to: square, hex, and double “D” holes.
