Value Collection C1100406 Woodruff Keyseat Cutter

Product Description

The VALUE COLLECTION C1100406 is a Woodruff keyseat cutter designed for milling the semicircular keyseats found in shafts and mating components. It features a 0.75-inch cutting diameter and a 0.125-inch cutting width, making it suited for standard Woodruff key slot applications. The cutter is ground from high speed steel (HSS) and left uncoated with a bright finish, providing good edge retention across a range of ferrous and non-ferrous workpiece materials. With 10 straight teeth and a 0.5-inch shank diameter, it mounts directly into standard milling machine collets or end mill holders. Machinists and toolroom technicians are the primary users of this tool.

This cutter conforms to ANSI Standard Number 406 (Old Standard Number 7), positioning it as a direct fit for keyseat work on shafts requiring a 0.75-inch wide by 0.125-inch deep seat profile. It is used in general machining environments including job shops, maintenance and repair operations, and production toolrooms where Woodruff key drives are specified on rotating assemblies such as pump shafts, motor shafts, and gearbox components. The 2.125-inch overall length provides adequate reach for standard milling setups.

Compatibility

Conforms to ANSI Standard Number 406 (Old Standard Number 7). Designed as an OEM-style replacement or direct-use cutter for any milling application requiring a standard Woodruff keyseat of this size class.

Installation Notes

This cutter is installed by machinists in milling machines equipped with a 0.5-inch collet or end mill holder. Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the cutter. Secure the shank with appropriate torque per the machine tool manufacturer's collet or holder specification. Follow standard shop safety practices including the use of cutting fluid where appropriate for the workpiece material.
