The VALUE COLLECTION C2100404 is a Woodruff keyseat cutter designed for milling the semicircular keyseats used in shaft-and-hub assemblies. Built from M42 cobalt high-speed steel with a bright, uncoated finish, this cutter delivers solid wear resistance in ferrous and harder workpiece materials. It features a 0.5-inch cut diameter, a 0.125-inch cutting width, and a 1/2-inch shank diameter for secure tool-holder engagement. With 10 straight teeth and a 2.125-inch overall length, it conforms to ANSI standard 404 (Old Standard Number 3). Machinists and tool-and-die workers use this type of cutter on milling machines and machining centers where precise keyseat geometry is required.
This cutter is suited for producing Woodruff keyseats in shafts, spindles, and similar components where a half-moon key fits into a mating hub keyway. It is appropriate for general-purpose machine shop use in both production and maintenance environments. The straight-tooth configuration is effective in conventional milling operations on steel, cast iron, and similar materials. Typical applications include pump shafts, motor shafts, and gearbox components where Woodruff keys are specified by design or drawing.
Designed as an OEM-style replacement or direct-use Woodruff keyseat cutter conforming to ANSI standard 404, suitable for use in standard 1/2-inch shank tool holders on vertical milling machines and machining centers.
Installation and use of this cutter is performed by qualified machinists on milling machines or machining centers. Secure the 1/2-inch shank firmly in an appropriate end mill holder or collet chuck before operation, and verify runout before cutting. Always power down and lock out the spindle before mounting or removing the cutter. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
