Value Collection SC2082020 Countersink 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2082020 is a single-end, 6-flute countersink designed for right-hand cutting in metalworking and fabrication applications. It features an 82-degree included angle — the standard for flat-head fastener seating — and is manufactured from high-speed steel with a bright, uncoated finish. The straight-cylindrical shank measures 1/4 inch in diameter and 1 inch in shank length, with a 5/16 inch head diameter. This tool is suited for machinists, tool-and-die technicians, and maintenance mechanics who need a reliable, no-frills countersink for production or bench work.

This countersink is used in metalworking shops, MRO maintenance environments, and light manufacturing settings where countersinking operations are performed on steel, aluminum, brass, and similar materials. The 82-degree angle is consistent with the ANSI flat-head screw standard, making it appropriate for creating flush-seating recesses for that fastener type. The 1/4 inch straight shank is compatible with standard drill chucks and collet holders commonly found in drill presses, milling machines, and handheld power drills.

Key Features

• 82-degree included angle meets ANSI flat-head fastener seating standard
• 6-flute geometry provides smooth cutting action and reduces chatter
• High-speed steel construction handles a wide range of common metals
• Bright/uncoated finish — no coating buildup concerns for general-purpose use
• 1/4 inch straight-cylindrical shank fits standard drill chucks and collets
• Single-end design with no pilot — suitable for use with or without a pilot guide

Compatibility

Designed as a general-purpose countersink compatible with standard drill chucks and collet-style holders accepting a 1/4 inch straight shank. Suitable for countersinking operations on steel, aluminum, and other common workpiece materials.

Installation Notes

This tool is installed by a machinist or maintenance technician into a drill press, milling machine, or handheld power drill with a compatible 1/4 inch chuck or collet. Secure the shank firmly before operation to prevent slippage. Use appropriate cutting fluid or coolant when countersinking hardened or heat-sensitive materials. Inspect the cutting flutes for wear or chipping before each use.
