Value Collection SC2082016 Countersink 82 Degree 6 Flute

Product Description

The VALUE COLLECTION SC2082016 is a single-end, 6-flute countersink designed for right-hand cutting in metal and other standard workshop materials. Built from high-speed steel (HSS) with a bright uncoated finish, it delivers consistent performance on countersinking operations where a clean, accurate 82-degree included angle is required. The straight cylindrical shank measures 0.25 inches in diameter with a shank length of 1 inch, and the cutting head diameter is also 0.25 inches. This tool is sized for use in drill presses, milling machines, and hand drills with compatible collets or drill chucks.

This countersink is suited for residential and commercial shop environments, production lines, and maintenance applications where flat-head fastener seat preparation is a routine task. The 82-degree included angle matches the standard seat geometry for imperial flat-head screws and machine screws commonly used in fabrication, HVAC equipment assembly, electrical enclosures, and plumbing fixture installations. It is installed and operated by machinists, tool-and-die professionals, and skilled tradespeople who require accurate countersink geometry without a pilot guide.

Key Features

• 82-degree included angle (41-degree centerline angle) matches standard imperial flat-head fastener geometry
• 6-flute design provides smoother cutting action and better chip evacuation compared to fewer-flute versions
• High-speed steel construction handles steel, aluminum, brass, and similar materials
• Bright uncoated finish suitable for general-purpose countersinking applications
• Straight cylindrical shank fits standard drill chucks and collets without modification
• Single-end, no-pilot design allows use across a range of hole diameters without a dedicated guide

Compatibility

Designed as a general-purpose OEM-style countersink compatible with standard drill presses, CNC machines, and handheld drills accepting a 0.25-inch straight cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists or trained tradespeople familiar with rotating cutting tools. Secure the workpiece firmly before engaging the tool, and ensure the spindle speed is appropriate for the workpiece material and tool diameter. Wear appropriate eye protection and follow applicable OSHA and shop-safety guidelines when operating cutting tools. Do not exceed the recommended RPM for the material being worked.
