Value Collection SC4082056 Countersink 82 Degree 3 Flute

Product Description

The VALUE COLLECTION SC4082056 is a single-end, 3-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel with a bright uncoated finish, it features an 82-degree included angle and a 7/8-inch head diameter. The straight-cylindrical shank measures 1/2 inch in diameter for secure chuck engagement. Weighing 0.5 pounds, this tool is suited for machinists, tool-and-die techs, and maintenance professionals who need consistent countersink geometry for fastener seating and hole preparation.

This countersink is used in general metalworking, maintenance repair, and light manufacturing environments where 82-degree flat-head fastener prep is required. The 3-flute design provides a balance of cutting speed and surface finish quality in ferrous and non-ferrous materials. It fits standard drill presses, milling machines, and hand drill setups with a 1/2-inch chuck or collet. No pilot is included, making it appropriate for use with a drill press vise or center-guided fixture to maintain hole alignment.

Key Features

• 82-degree included angle (41-degree centerline angle) for standard flat-head fastener countersinking
• 3-flute geometry balances material removal rate with finish quality
• High-speed steel construction provides durability across ferrous and non-ferrous workpieces
• Bright uncoated finish — no coating buildup risk in tight-tolerance applications
• 1/2-inch straight-cylindrical shank fits standard drill chucks and collets
• Single-end design with no pilot for flexible use across hole sizes

Compatibility

Designed as a standard-geometry countersink for use in drill presses, milling machines, and hand drills equipped with a 1/2-inch chuck or collet, suitable for countersinking 82-degree flat-head fastener holes in metal, wood, and composite materials.

Installation Notes

Machinists and maintenance technicians should secure the workpiece firmly before operation to prevent walkout, as this tool does not include a pilot. Use appropriate cutting fluid or lubricant when working ferrous metals to extend tool life and improve finish. Always verify spindle speed is set to a rate appropriate for the workpiece material and head diameter before engaging the cut. Inspect the shank seating in the chuck or collet before each use to confirm concentricity.
