Value Collection SC5082D7 Countersink 82 Deg Hss

Product Description

The VALUE COLLECTION SC5082D7 is a single-end, straight-shank countersink designed for countersinking and deburring operations in metal and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool features an 82-degree included angle and a 41-degree centerline angle, making it suited for standard flathead fastener seat preparation. The shank diameter measures 5/8 inches, and the tool accepts a cutting diameter range from 1 inch minimum to 2 inches maximum. It is a flute-free design, meaning it operates as a burring-style countersink rather than a chip-fluted cutter. Machinists, toolmakers, and general shop technicians are the typical end users.

This countersink is used in machine shop, fabrication, and general metalworking environments where flathead screw seats or chamfered hole entries are required. The 82-degree angle corresponds to the standard included angle for 82-degree flathead fasteners commonly used in aerospace and industrial assembly. The 1 to 2 inch cutting diameter range positions this tool for larger-diameter countersink work, beyond the range of standard small-shank countersinks. It is appropriate for use in drill presses, milling machines, or CNC setups where a straight-cylindrical shank mount is available.

Key Features

• 82-degree included angle matches standard flathead fastener geometry for accurate seat preparation
• High-speed steel construction provides durability across a range of workpiece materials
• Cutting diameter range of 1 inch to 2 inches handles larger countersink applications
• 5/8-inch straight-cylindrical shank for secure chuck or collet mounting
• Bright, uncoated finish for straightforward inspection and general-purpose use
• Suitable for both countersinking and deburring operations in a single tool

Compatibility

Designed as an OEM-style replacement or direct-use countersink for machine shop and fabrication setups requiring a straight-cylindrical shank countersink with an 82-degree included angle and a 1 to 2 inch cutting diameter range.

Installation Notes

This tool is installed and operated by machinists or toolroom technicians. Secure the 5/8-inch straight shank firmly in an appropriate drill chuck, end mill holder, or collet before operation. Always power down and lock out the machine before changing tooling. Do not exceed the cutting diameter range of the tool or use it on workpiece materials beyond the rated capability of high-speed steel without verifying appropriateness.
