Value Collection 28632 Countersink 1 in 82 Degree 6 Flute Hss

Product Description

The VALUE COLLECTION 28632 is a single-piece countersink bit designed to chamfer and deburr pre-drilled holes in metal, wood, and composite materials. It features a 1-inch head diameter and an 82-degree included angle, making it well suited for flathead fastener seating applications that require a flush or recessed finish. The 6-flute design distributes cutting load evenly, reduces chatter, and produces a smoother surface finish compared to lower flute-count alternatives. The tool is manufactured from high speed steel, providing adequate hardness and wear resistance for general-purpose machining operations. Machinists, tool-and-die workers, and maintenance technicians are the primary installers of this style of countersink.

This countersink is used in general metalworking, fabrication, and machine shop environments where consistent chamfer geometry is required ahead of flathead fastener installation. The 82-degree included angle is the standard angle for unified inch-series flathead screws, making this tool appropriate for production and repair work on steel, aluminum, and similar workpiece materials. The 1/2-inch shank diameter is compatible with standard drill chucks and collet holders commonly found in drill presses, milling machines, and hand drills.

Key Features

• 1-inch head diameter for chamfering larger-diameter holes and fastener seats
• 82-degree included angle matches unified inch-series flathead fastener geometry
• 6-flute construction minimizes chatter and improves surface finish quality
• High speed steel construction provides hardness suitable for general-purpose metalworking
• 1/2-inch shank diameter fits standard drill chucks and collet holders

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and hand drills equipped with a 1/2-inch or larger chuck or collet system. Suitable for flathead fastener applications using unified inch-series screw standards.

Installation Notes

This tool is installed and operated by machinists, fabricators, or maintenance technicians using standard rotating machine equipment. Secure the workpiece firmly before operation and ensure the spindle is fully stopped before changing or inspecting the bit. Use appropriate cutting fluid or lubricant when countersinking steel to extend tool life and improve finish quality. Follow applicable shop safety standards and wear appropriate eye protection during all machining operations.
