Value Collection C1100403 Woodruff Keyseat Cutter Hss

Product Description

The VALUE COLLECTION C1100403 is a Woodruff keyseat cutter designed for milling the semicircular keyway slots used in shaft-and-hub assemblies. Built from high speed steel (HSS) with a bright, uncoated finish, this cutter features a 0.375 inch cutting diameter, a 0.125 inch cutting width, and a 0.5 inch straight shank that mounts directly into standard milling machine collets or arbor holders. With 6 straight teeth and an overall length of 2.125 inches, it produces clean, accurate Woodruff key slots in steel, aluminum, and similar materials. It meets ANSI Standard Number 403, also referenced as Old Standard Number 213. Machinists and tool-and-die professionals rely on this type of cutter for precision keyseat work on rotating shafts.

This cutter is suited for use on manual knee mills and CNC milling machines in job shop, maintenance, and production environments. Typical applications include cutting Woodruff keyseats on motor shafts, spindles, and similar components where a keyed connection is required between a shaft and a gear, pulley, or hub. The straight tooth configuration is well suited to conventional milling operations where chip clearance and tool rigidity are priorities.

• 0.125 inch cutting width produces a precise, standard-width slot
• High speed steel construction provides wear resistance across common workpiece materials
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• 6 straight teeth for clean slot geometry and consistent chip evacuation
• 0.5 inch shank diameter fits standard milling collets and tool holders

Compatibility

Designed as a standard ANSI 403 Woodruff keyseat cutter, also catalogued under Old Standard Number 213, compatible with milling machines equipped with a 0.5 inch collet or arbor holder.

Installation Notes

Installation and use of this cutter should be performed by a qualified machinist familiar with milling machine operation and cutting tool safety. Secure the shank firmly in a properly sized collet or tool holder before operation and verify runout before cutting. Always power down and lock out the machine before changing cutters. Feed direction, spindle speed, and depth of cut should be selected based on workpiece material and machine capability — do not exceed the tool manufacturer's recommended parameters for HSS tooling.
