Keo 943-000-049 Woodruff Keyseat Cutter Hss Straight Tooth

Product Description

The KEO 943-000-049 is a Woodruff keyseat cutter designed for milling keyseat slots in shafts and other machined components. It features a straight tooth configuration, a 0.51-inch cut diameter, and a 0.0625-inch cutting width, making it suited for precision slotting operations requiring tight dimensional control. Manufactured from high speed steel (HSS) with a bright, uncoated finish, this cutter is built for use in manual and CNC milling applications. It has a 0.5-inch shank diameter and an overall length of 2.0625 inches. Installation is handled by machinists and toolroom professionals working to ANSI standard 204.

This cutter is appropriate for both production and maintenance machining environments where Woodruff keyseats must be cut to standard dimensions. The 943-000-049 is rated for use on a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hardened alloys. It carries the ANSI 204 designation and corresponds to Old Standard Number 1, making it a direct fit for applications calling out either standard. Typical use cases include shaft keyway preparation in drive assemblies, gear hubs, and pulley mountings.

Key Features

• Straight tooth configuration for clean, consistent keyseat slot geometry
• High speed steel construction provides durability across a wide range of workpiece materials including hardened alloys and superalloys
• Bright, uncoated finish - no coating to chip or delaminate during regrinding
• Conforms to ANSI 204 and Old Standard Number 1 for straightforward specification matching
• 0.3750-inch neck length supports reach into standard keyseat depths without interference
• Not oversized - ground to nominal dimension, suitable for direct application without post-grind compensation

Compatibility

Designed as an OEM-style Woodruff keyseat cutter conforming to ANSI standard 204 (Old Standard Number 1), compatible with standard 0.5-inch shank milling arbors and collet holders. Suitable for cutting keyseats in steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hardened alloys.

Installation Notes

This cutter is installed and operated by machinists using a milling machine with an appropriate arbor or collet rated for a 0.5-inch shank. The workpiece and machine spindle must be fully stopped and locked out before mounting or removing the cutter. Verify that the arbor and cutter mating surfaces are clean and free of chips before tightening. Follow applicable shop safety standards and machine manufacturer guidelines for speeds and feeds based on workpiece material.
