Value Collection C2100202 Woodruff Keyseat Cutter

Product Description

The VALUE COLLECTION C2100202 is a Woodruff keyseat cutter designed for machining semicircular keyseats into shafts and bores. It features a 0.25 inch cut diameter and a 0.0625 inch cutting width, making it suited for precision slotting work on small shaft assemblies. The cutter is manufactured from M42 cobalt high-speed steel, which provides increased heat resistance and hardness retention compared to standard M2 HSS — an important characteristic when cutting harder workpiece materials or running at elevated feeds. The bright, uncoated finish keeps the cutting edges sharp and clearly visible for inspection. Machinists, tool and die makers, and maintenance technicians use this style of cutter on manual or CNC milling machines.

This keyseat cutter is suited for applications in general machining, maintenance repair, and toolroom work where Woodruff key slots are required in shafts, spindles, or similar cylindrical components. With 6 straight teeth, it produces clean, flat-bottomed slots consistent with the ANSI 202 standard (Old Standard 201). A 0.5 inch straight shank seats in standard collet chucks or end mill holders. The 2.0625 inch overall length provides adequate reach for most standard milling setups without excessive overhang.

Key Features

• M42 cobalt HSS construction for improved hardness and heat resistance over standard HSS
• 0.25 inch cut diameter and 0.0625 inch cutting width per ANSI Standard 202
• 6 straight teeth for clean, flat-bottomed Woodruff keyseats
• Bright, uncoated finish — no additional coating to affect edge geometry
• 0.5 inch straight shank for use in standard collet chucks and end mill holders
• 2.0625 inch overall length for versatile setup in vertical or horizontal milling machines

Compatibility

Designed as an OEM-style replacement or standard toolroom cutter conforming to ANSI 202 (Old Standard 201) for use in any milling machine equipped with a 0.5 inch collet or end mill holder.

Installation Notes

This cutter is installed and operated by machinists on vertical or horizontal milling machines. Secure the 0.5 inch shank firmly in a collet chuck or end mill holder before beginning the cut, and verify runout before engaging the workpiece. Always ensure the spindle is fully stopped and the machine is powered down before changing or inspecting cutters. Use appropriate cutting fluid or coolant recommended for cobalt HSS tooling when cutting harder alloys.
