Value Collection SC3082100 Countersink 82 Deg 4 Flute Hss

Product Description

The VALUE COLLECTION SC3082100 is a single-end, 4-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright/uncoated finish, this tool produces clean, chamfered seat geometry for fastener heads in ferrous and non-ferrous materials. The 82-degree included angle (41-degree centerline angle) matches standard flat-head screw specifications used widely in manufacturing and assembly work. With a 1-inch head diameter and a 0.5-inch straight-cylindrical shank, this countersink fits standard drill chucks and collet systems without adapters. No pilot is included, making it a dedicated countersinking tool run at controlled feed rates for precision results.

This countersink is suited for job-shop machining, maintenance and repair operations, and production assembly environments where accurate countersink geometry is required. It is appropriate for use in drill presses, CNC machining centers, and manual milling setups. The 82-degree angle is the standard specification for flat-head fasteners in aerospace and general metalworking applications. Machinists and tooling technicians working with carbon steel, alloy steel, aluminum, and similar materials will find this tool compatible with common shop workflows requiring precise countersink seat preparation.

Key Features

• 82-degree included angle matches standard flat-head fastener seat geometry
• 4-flute design promotes smooth cutting action and reduced chatter
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• Bright/uncoated finish with no pilot — dedicated countersinking without pilot interference
• 0.5-inch straight-cylindrical shank fits standard drill chucks and collet holders
• Single-end tool for straightforward chuck mounting and replacement

Compatibility

Designed as an OEM-style replacement countersink for use in drill presses, CNC machining centers, and manual mill setups accepting a 0.5-inch straight-cylindrical shank.

Installation Notes

Installation and operation of this countersink should be performed by a qualified machinist or tooling technician. Secure the shank fully in a drill chuck or collet before operation and verify zero runout before cutting. Power down and de-energize the spindle completely before changing or adjusting the tool. Follow machine manufacturer guidelines for appropriate spindle speed and feed rate when countersinking the target material.
