Value Collection C1200710 Woodruff Keyseat Cutter Hss Ansi 710

Product Description

The VALUE COLLECTION C1200710 is a Woodruff keyseat cutter designed for milling semicircular keyseats into shafts and mating components. Built from high speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in general machining and tool room applications. The cutter measures 1.25 inches in diameter with a 0.2188 inch (7/32 inch) cutting width and a 1/2 inch shank diameter, giving it a compact, controlled profile suited for standard Woodruff key slot work. With 14 staggered teeth and a 2.2188 inch overall length, it produces smooth cuts while reducing chatter on manual and CNC milling machines alike.

This cutter is used in machine shops, maintenance facilities, and production environments where Woodruff key slots are required in shafts, hubs, and similar workpieces. The staggered tooth configuration handles both ferrous and non-ferrous materials commonly encountered in general mechanical assembly. It conforms to ANSI Standard Number 710, also referenced under Old Standard Number 20, making it a direct fit for shops specifying keyseat cutters by those designations. Machinists and tool and die makers are the primary users.

Key Features

• 1.25 inch cut diameter produces a standard Woodruff keyseat profile
• 0.2188 inch (7/32 inch) cutting width matches ANSI 710 slot dimensions
• 14 staggered teeth reduce chatter and improve surface finish
• High speed steel construction provides good wear resistance across common workpiece materials
• Bright, uncoated finish — no coating variables to account for during setup
• 1/2 inch shank diameter fits standard milling machine collets and arbors

Compatibility

Conforms to ANSI Standard Number 710 (Old Standard Number 20). Designed as a standard Woodruff keyseat cutter for use in any milling machine or horizontal mill accepting a 1/2 inch shank.

Installation Notes

Installation is performed by machinists on manual or CNC milling machines. Secure the 1/2 inch shank in a properly sized collet or arbor before beginning any cut, and confirm the machine spindle is fully stopped before tool changes. Set cutting depth and feed rate according to the workpiece material and machine capability — do not force the cutter beyond its rated geometry. Inspect the cutter for chipped or worn teeth before each use.
