Value Collection C21001211 Woodruff Keyseat Cutter

Product Description

The VALUE COLLECTION C21001211 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, it delivers reliable cutting performance on a range of ferrous and non-ferrous workpiece materials. The cutter measures 1.375 inches in cutting diameter with a 0.375-inch cutting width, runs on a 1/2-inch shank, and carries 14 straight teeth arranged for clean, stable cuts. Machinists and toolroom technicians install this cutter on manual or CNC milling machines wherever precise Woodruff keyseat geometry is required.

This cutter is suited for production and maintenance machining operations that require ANSI 1211 (Old Standard F) Woodruff keyseat geometry. Typical applications include cutting keyseats in motor shafts, pump shafts, gear bores, and similar power-transmission components in both job-shop and industrial maintenance environments. The straight-tooth configuration makes it appropriate for conventional milling passes where a consistent, flat-bottomed keyseat profile is needed.

Key Features

• M42 cobalt HSS construction provides increased heat and wear resistance compared to standard M2 HSS cutters
• 14 straight teeth deliver a stable cutting action and a clean keyseat floor
• Conforms to ANSI 1211 (Old Standard F) Woodruff keyseat standard for consistent fit with mating keys
• Bright, uncoated finish suitable for general-purpose machining without added coating cost
• 1/2-inch shank diameter fits standard milling machine arbors and collet chucks
• 2.375-inch overall length provides adequate clearance in typical milling setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for milling machines accepting a 1/2-inch shank Woodruff keyseat cutter conforming to ANSI standard 1211.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with milling machine setup and cutting-tool safety. Ensure the milling machine spindle is fully stopped and locked out before mounting or removing the cutter. Secure the shank firmly in the arbor or collet to the machine manufacturer's specification before cutting. Use appropriate cutting fluid or coolant for the workpiece material, and do not exceed the recommended feed and speed parameters for cobalt HSS tooling.
