   Davis Keyseater Keyway Cutting
Our Davis Keyseaters have a keyway capacity of 1/16" to 1-1/2" wide and up to 18" high.

Using the multiple tooth cutter principle, the DAVIS KEYSEATER is the fastest cutting, most precise, and easiest to operate keyseater on the market.

The DAVIS KEYSEATER is unequalled by other keyseaters in terms of cutting speed and precision. Davis multiple tooth cutters allow more strokes per minute, are faster cutting than single tooth cutters, save set-up time and eliminate length of stroke adjustments. Actual cases of cutting times in various materials using the Model 15 DAVIS KEYSEATER (Automatic) are described below.
