Value Collection SC2082048 Countersink 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2082048 is a single-end, 6-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright/uncoated finish, it features an 82-degree included angle and a straight-cylindrical shank measuring 0.5 inches in diameter. The shank length is 1.3125 inches, and the head diameter is 0.75 inches. This countersink does not include a pilot and is intended for use in drill presses, CNC machines, and handheld power tools where controlled countersinking of fastener seats is required. Machinists, tool-and-die workers, and maintenance technicians are the primary users.

The SC2082048 is suited for countersinking screw and bolt holes in steel, aluminum, and other common metals in both shop and field settings. The 82-degree included angle matches the standard flat-head machine screw geometry used in most industrial and general-purpose assembly work. Its straight-cylindrical shank seats securely in standard drill chucks and collet holders without modification.

Key Features

• 82-degree included angle matches standard flat-head fastener geometry
• 6-flute design provides smooth cutting action and improved chip evacuation
• High-speed steel construction handles a broad range of common metals
• Bright/uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Single-end design; no pilot included for use with pre-drilled pilot holes

Compatibility

Designed as a general-purpose countersink for use in drill presses, CNC machining centers, and power drills equipped with a standard chuck or collet accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, CNC machine, or handheld drill. Secure the shank fully in the chuck or collet before operation and verify that the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid or lubricant when countersinking harder metals to extend tool life. Inspect the cutting edges for wear before each use and replace the tool if chipping or dullness is observed.
