Value Collection SC4060040 Countersink 60 Degree 3 Flute

Product Description

The VALUE COLLECTION SC4060040 is a single-end, 3-flute countersink designed for right-hand cutting in metal fabrication and general machining applications. Built from high-speed steel (HSS) with a bright/uncoated finish, it features a 60-degree included angle and a 5/8-inch head diameter. The straight-cylindrical shank measures 3/8 inch in diameter with a 1-inch shank length, making it compatible with standard drill chucks and countersink holders. This tool is suited for deburring holes and creating chamfered seat profiles for flat-head fasteners in production and maintenance environments. No pilot is included.

This countersink is used in metal shop, manufacturing, and maintenance-repair-operations (MRO) settings where precise chamfer angles are required before fastener seating. It is appropriate for use in steel, aluminum, and similar workpiece materials typical of light-to-medium machining work. The 60-degree included angle matches standard flat-head machine screw seat geometry commonly encountered in precision assemblies. Machinists, tool-and-die technicians, and maintenance mechanics are the typical end users for this style of countersink.

Key Features

• 60-degree included angle for standard flat-head fastener seating
• 3 flutes for improved chip evacuation and surface finish
• High-speed steel construction for durability across common workpiece materials
• Bright/uncoated finish — suitable for general-purpose countersinking
• Straight-cylindrical 3/8-inch shank fits standard drill chucks and holders
• Single-end design with no pilot — maximizes flexibility across hole sizes

Compatibility

Designed as a general-purpose countersink for use in standard drill presses, milling machines, and hand-drill applications that accept a 3/8-inch straight-cylindrical shank.

Installation Notes

Countersinks are installed and operated by machinists and maintenance technicians using standard drill chucks or dedicated countersink holders. Secure the workpiece fully before operation to prevent rotation or movement. Run at appropriate spindle speeds for the workpiece material — higher speeds for aluminum, reduced speeds for steel — following the tool manufacturer's general speed-and-feed guidelines. Inspect the cutting edges for wear before each use and replace when the chamfer finish degrades.
