Value Collection SC2182024 Countersink 3/8 in 82 Deg 6 Flute

Product Description

The VALUE COLLECTION SC2182024 is a single-end cobalt steel countersink designed for creating accurate, chamfered seat profiles in ferrous and high-strength materials. With a 3/8-inch head diameter and an 82-degree included angle, this tool produces the correct seat geometry for flat-head fasteners conforming to standard 82-degree specifications. The 6-flute configuration delivers smooth cutting action and a clean finish in a single pass. The straight-cylindrical, 1/4-inch shank mounts directly into standard drill chucks or quick-change holders. This countersink is sold individually and arrives with a bright, uncoated finish ready for immediate use.

This countersink is suited for use in metal fabrication, maintenance and repair, and light manufacturing environments where precise countersinking of pilot-drilled holes is required. The 82-degree angle matches the seating geometry of most common flat-head machine screws and sheet metal screws used across industrial and commercial applications. Machinists, tool-and-die technicians, millwrights, and skilled maintenance trades will find this tool appropriate for bench-drill, drill-press, and hand-drill use on steel, stainless, and similar materials.

Key Features

• Cobalt steel construction for improved heat and wear resistance in harder workpiece materials
• 82-degree included angle matches standard flat-head fastener seating geometry
• 6-flute design reduces chatter and produces a smoother countersink surface
• 3/8-inch head diameter suitable for common flat-head screw sizes
• 1/4-inch straight-cylindrical shank fits standard drill chucks and quick-change systems
• Bright, uncoated finish — no pilot, single-end configuration for straightforward setup

Compatibility

Designed as an OEM-style replacement or direct-use countersink for drill-press and hand-drill applications requiring an 82-degree flat-head seat profile with a 1/4-inch shank interface.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance tradespeople familiar with rotating cutting tools. Secure the 1/4-inch shank firmly in the chuck before operation and verify that the workpiece is clamped or fixtured to prevent movement. Always start the countersink in a pre-drilled pilot hole to maintain concentricity and reduce side-loading on the flutes. Use appropriate cutting fluid for steel applications and inspect the cutting edges for wear before each use.
