Value Collection SC3082032 Countersink 82 Deg 4 Flute Hss

Product Description

The VALUE COLLECTION SC3082032 is a 4-flute, single-end countersink designed for right-hand cutting in metal fabrication and general machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance without a pilot. The included angle measures 82 degrees with a centerline angle of 41 degrees, making it suited for standard fastener seat preparation. The straight-cylindrical shank measures 0.5 inches in diameter with a shank length of 2.25 inches. This tool is typically installed in a drill press, milling machine, or hand drill by machinists and tool-and-die tradespeople.

This countersink is used to create angled seats for flat-head screws and fasteners in sheet metal, aluminum, mild steel, and similar workpiece materials. The 82-degree included angle matches the seating geometry required by many aerospace and industrial flat-head fastener standards. It is suited for both production and maintenance environments where a clean, burr-free countersink seat is required without a pilot guide.

Key Features

• 82-degree included angle for flat-head fastener seat preparation
• 4-flute design for smooth, chatter-resistant cutting action
• High-speed steel construction for durability across common metals
• Bright/uncoated finish — no coating buildup affecting dimensional accuracy
• Straight-cylindrical shank, 0.5 inches diameter, compatible with standard chucks
• Single-end, no-pilot design for use with drill press or hand-held setups

Compatibility

Designed as an OEM-style replacement or standard tooling option for drill presses, milling machines, and hand drills accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tradesperson familiar with rotary cutting tools. Secure the straight-cylindrical shank firmly in the chuck before operation and ensure the workpiece is clamped to prevent movement. Use appropriate cutting fluid or lubrication when countersinking steel to extend tool life and improve finish quality. Inspect the cutting edges before each use and replace the tool if chipping or wear is detected.
