Value Collection C1100505 Woodruff Keyseat Cutter Hss Ansi 505

Product Description

The VALUE COLLECTION C1100505 is a Woodruff keyseat cutter designed for milling semicircular keyways into shafts and mating components. It features a 0.625-inch cut diameter and a 0.1563-inch (5/32 inch) cutting width, with a straight-tooth configuration that provides clean, consistent cuts in keyseat applications. The cutter is ground from high speed steel (HSS) with a bright, uncoated finish and carries ANSI Standard Number 505 (Old Standard 6). The 1/2-inch straight shank mounts directly into standard milling machine collets or arbors, making setup straightforward for machinists and tool-and-die professionals.

This keyseat cutter is suited for use on manual milling machines and CNC mills in machine shops, maintenance facilities, and production environments. It is used when cutting Woodruff keyseats in accordance with ANSI standards on shafts sized for the No. 505 keyseat profile. Applications include shaft-to-hub assemblies in mechanical drives, gearboxes, and general power transmission components where a properly fitted Woodruff key is required. The 8-tooth straight configuration is appropriate for both ferrous and non-ferrous workpiece materials at standard cutting speeds for HSS tooling.

Key Features

• 0.625-inch cut diameter and 0.1563-inch cutting width per ANSI 505 standard
• Straight-tooth design for consistent keyseat geometry
• High speed steel construction for durability across common workpiece materials
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• 1/2-inch straight shank for compatibility with standard collets and arbors
• 8 teeth for smooth chip evacuation in keyseat milling operations

Compatibility

Designed as an ANSI 505 Woodruff keyseat cutter (Old Standard 6) for use in standard milling machine setups requiring a 0.625-inch diameter, 0.1563-inch wide keyseat profile on a 1/2-inch shank.

Installation Notes

Installation is performed by machinists using a vertical or horizontal milling machine. Secure the shank firmly in a collet or arbor before cutting and verify runout before engaging the workpiece. Follow standard shop safety practices including workholding, speed and feed selection appropriate for HSS tooling, and eye protection. Do not exceed the rated cutting geometry for the selected workpiece material.
