Value Collection SC1082040 Countersink 82 Degree Hss

Product Description

The VALUE COLLECTION SC1082040 is a single-flute, high-speed steel countersink designed for creating clean, chamfered seat profiles in metal and wood substrates. Built with an 82-degree included angle and a bright, uncoated finish, it is suited for standard flathead fastener preparation where consistent countersink geometry is required. The straight-cylindrical shank measures 0.5 inches in diameter, making it compatible with standard drill chucks and countersink holders. With a head diameter of 0.625 inches and a 41-degree centerline angle, it delivers accurate, repeatable results. This tool is typically used by machinists, sheet metal workers, and maintenance tradespeople working with ferrous and non-ferrous materials.

This countersink is intended for general countersinking operations in light manufacturing, maintenance, and fabrication environments. The single-flute design reduces chatter during hand-drill or drill-press operation, making it practical for spot deburring and flathead screw seat prep on steel, aluminum, and plastic. It is a right-hand cutting tool and is used without a pilot, making it suitable for freehand countersinking where a pre-drilled hole guides entry. No pilot is included, so the operator relies on the existing hole for alignment.

Key Features

• 82-degree included angle matches standard flathead fastener geometry
• Single flute reduces chatter for cleaner entry in hand-drill applications
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• 0.5-inch straight-cylindrical shank fits standard drill chucks and countersink holders
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Right-hand cutting direction compatible with standard drill rotation

Compatibility

Designed as a general-purpose countersink for use in drill presses, hand drills, and milling machines accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

This tool is installed by machinists and general tradespeople using standard drill chucks or tool holders. Ensure the drill or press is powered off and the chuck is fully secured before beginning operation. Use appropriate workholding to prevent the workpiece from rotating during the countersinking operation. Do not exceed the recommended spindle speeds for the material being cut, and inspect the cutting edge for wear before each use.
