Value Collection FAC0660CO Cobalt Face Angle Cutter

Product Description

The VALUE COLLECTION FAC0660CO is a cobalt face angle cutter designed for precision countersinking, chamfering, and deburring operations on metal workpieces. Built from uncoated cobalt high-speed steel, it delivers reliable cutting performance in ferrous and non-ferrous materials where heat resistance and edge retention are required. The cutter features a 60-degree included angle, a 3/4-inch large diameter, and a 5/16-inch small diameter, with a 17/32-inch width of cut. The 3/8-inch shank diameter with a Weldon flat provides positive drive and resists slippage under load. Overall length is 2-3/32 inches. Machinists and toolroom techs reach for this style of cutter when a consistent chamfer angle and clean finish are the primary objectives.

This cutter is suited for use in vertical machining centers, drill presses, and manual knee mills. It handles countersinking bolt-hole patterns, chamfering sharp edges before assembly, and spot-facing operations on steel, cast iron, aluminum, and similar materials. The Weldon flat shank is compatible with standard end mill holders and side-lock toolholders, making it straightforward to set up in most shop environments. It is typically installed by machinists, tool-and-die makers, and maintenance technicians working in job shops, production facilities, or industrial maintenance settings.

Key Features

• Cobalt high-speed steel construction for improved heat resistance and edge retention compared to standard HSS
• 60-degree included angle for standard chamfering and countersinking applications
• 3/4-inch large diameter with 17/32-inch width of cut for consistent material removal
• 3/8-inch shank with Weldon flat for positive drive in side-lock and end mill holders
• Uncoated finish — suitable for use with cutting fluid on ferrous and non-ferrous materials
• Compact 2-3/32-inch overall length for use in tight setups and short-reach applications

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for 3/8-inch shank end mill holders and side-lock toolholders with Weldon flat seats, as found on standard vertical machining centers and drill press setups.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the shank fully in a side-lock holder, aligning the set screw to the Weldon flat before tightening to prevent axial movement. Ensure the spindle is at a complete stop and the machine is powered down before changing or inspecting cutters. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
