Harvey Tool 905250 Woodruff Keyseat Cutter Solid Carbide

Product Description

The HARVEY TOOL 905250 is a Woodruff keyseat cutter designed for milling keyseat slots in rotating shafts and mating components. Built from brazed solid carbide with a straight tooth configuration, this cutter delivers consistent slot geometry in ferrous and non-ferrous materials. It features a 0.75-inch cut diameter, a 0.125-inch cutting width, and a 3/8-inch shank diameter. With 10 teeth and a 3.125-inch overall length, it suits precision keyway work in machine shops and maintenance environments. The bright, uncoated finish is suited for applications where coating buildup would compromise dimensional accuracy.

This cutter is appropriate for keyseat operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It connects via a standard shank interface without a Weldon flat, making it compatible with conventional collet and end mill holder setups. Typical use cases include shaft keyway milling on production and repair work in manufacturing, toolroom, and industrial maintenance settings. Machinists and tool-and-die professionals are the primary users of this cutter type.

Key Features

• Brazed solid carbide construction for rigidity and wear resistance in hard materials
• Straight tooth configuration provides clean, consistent keyseat profiles
• 0.75-inch cut diameter with a 0.125-inch cutting width for standard Woodruff keyseat dimensions
• 10-tooth design distributes cutting load and supports smooth chip evacuation
• 0.030-inch corner radius reduces stress concentration at slot corners
• Bright, uncoated finish suitable for ferrous and non-ferrous workpiece materials

Compatibility

Rated for use on primary workpiece materials including steel, stainless steel, and cast iron, as well as secondary materials including non-ferrous metals, superalloys, titanium, and hard materials. Fits standard 3/8-inch shank collets and end mill holders without a Weldon flat requirement.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with milling machine setup and speeds-and-feeds selection for carbide tooling. Secure the shank fully in a clean, undamaged collet or holder and verify runout before cutting. Do not exceed the cutter's recommended radial and axial depth-of-cut parameters for the workpiece material. Always power down and lock out the spindle before changing or inspecting the cutter.
