Value Collection SC4082024 Countersink 82 Deg 3 Flute Hss

Product Description

The VALUE COLLECTION SC4082024 is a single-end, straight-cylindrical-shank countersink designed for deburring and countersinking operations in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool features an 82-degree included angle and three flutes for smooth, controlled material removal. The 1/4-inch straight shank fits standard drill chucks and quick-change collet systems. With a 3/8-inch head diameter and a right-hand cutting direction, it produces clean, accurate countersink profiles in steel, aluminum, and similar materials. No pilot is included. Machinists, tool-and-die technicians, and fabricators are the primary users of this tool.

This countersink is suited for bench-top drill press work, CNC machining centers, and hand-held drill applications where an 82-degree countersink profile is required — the standard angle for flat-head machine screws used in most North American fastener applications. It is appropriate for light to medium production work in job shops, maintenance environments, and general metalworking. The single-end construction means the tool is replaced rather than re-indexed when worn.

Key Features

• 82-degree included angle matches the standard flat-head screw profile for North American fastener applications
• Three flutes provide balanced cutting action and reduce chatter on entry
• High-speed steel construction offers good toughness for interrupted cuts and general-purpose use
• Bright, uncoated finish suitable for use with cutting fluid or dry on non-ferrous materials
• 1/4-inch straight-cylindrical shank fits standard drill chucks and collets without an adapter
• No pilot required, allowing use across a range of hole diameters within the head capacity

Compatibility

Designed as a general-purpose countersink for use in standard drill chucks and collet holders accepting a 1/4-inch straight shank. Compatible with drill presses, milling machines, and hand-held power drills.

Installation Notes

This tool is installed and used by machinists and fabricators following standard machine-shop practices. Secure the shank firmly in the chuck or collet before use and verify runout is within acceptable limits to prevent chatter. Use a low spindle speed with cutting fluid when working hardened or stainless materials to extend tool life. Inspect the cutting edges before each use and replace the tool when flute edges show visible wear or chipping.
