Manufacturers of keyseat millers since 1903, these machine tool attachments mill full depth keyways in blind or open end bores in one pass. For use in gears, impellers, stub shafts, couplings, pump sleeves – any part requiring an internal keyway or slot. Closed-end oil slots, straight splines, radius arc splines, slots with radius corners or full radius and V-shaped or two-step keyways can be produced. Our company offers a complete line of stock-sized tools ranging from ½” to 3 ½” diameter with an array of cutter widths available to meet customer requirements. Custom designs are also available. Tooling is manufactured for manual machines and is adaptable to CNC equipment. As an alternative to EDM or right angle heads, our tools create a faster turnaround at significant cost savings.
