The HARVEY TOOL 23520 is a solid carbide Woodruff keyseat cutter designed for milling keyseat slots in shafts and bores. It produces a precise semicircular channel that accepts a Woodruff key, securing rotational components in drive assemblies and machine tooling applications. The cutter measures 0.3125 inches in cut diameter with a 0.056 inch cut width and runs on a 5/16 inch straight shank. Six straight teeth deliver clean, repeatable cuts in the slot profile. The solid carbide construction provides rigidity and wear resistance across a range of workpiece materials. Overall length is 2.5 inches.
This keyseat cutter is suited for machinists and toolmakers working on shafts, hubs, and mechanical assemblies where Woodruff key retention is required. Typical applications include production machining and repair work on motors, gearboxes, pumps, and rotating drive components. The straight tooth configuration makes it appropriate for conventional milling operations on manual knee mills and CNC machining centers alike. The bright, uncoated finish is well suited for use in non-ferrous and softer steel materials.
Designed as an OEM-style Woodruff keyseat cutter for use in standard 5/16 inch collets and tool holders on manual mills and CNC machining centers.
Installation and use should be performed by a qualified machinist familiar with milling operations and cutting tool safety. Secure the shank fully in a collet or end mill holder before running the spindle, and confirm that runout is within acceptable limits before cutting. Always follow the machine tool manufacturer's recommended speeds and feeds for carbide tooling, and use appropriate cutting fluid where the workpiece material requires it. Inspect the cutting edges for chipping or wear before each use.
