Value Collection SC4082032 Countersink 82 Deg 3 Flute Hss

Product Description

The VALUE COLLECTION SC4082032 is a single-end, 82-degree included-angle countersink designed for right-hand cutting in metal and general-purpose machining applications. Built from high-speed steel (HSS) with a bright/uncoated finish, it delivers reliable performance for countersinking fastener seats in ferrous and non-ferrous materials. The 3-flute geometry provides a smooth cutting action and a clean, chatter-reduced finish in the countersunk recess. With a 1/2-inch head diameter and a straight-cylindrical 3/8-inch shank, this tool mounts directly into standard drill presses, lathes, or hand drills without adapters.

This countersink is suited for shop, manufacturing, and maintenance applications where standard 82-degree flat-head fastener seating is required. It handles typical countersinking tasks in steel fabrication, sheet metal work, and general machining setups. The straight shank and common head geometry make it a practical everyday tool for machinists, maintenance technicians, and tool-and-die trades working with right-hand drilling equipment. No pilot is included, so the operator centers the tool using the existing clearance hole.

Key Features

• 82-degree included angle (41-degree centerline angle) matches standard flat-head fastener geometry
• 3-flute design reduces chatter and produces a cleaner countersunk finish
• High-speed steel construction handles ferrous and non-ferrous materials
• Bright/uncoated finish — no coating to chip or peel during regrinding
• Straight-cylindrical 3/8-inch shank fits standard drill chucks without adapters
• Single-end, no-pilot design for use with pre-drilled clearance holes

Compatibility

Designed as an OEM-style replacement or direct-use countersink compatible with standard 3/8-inch straight-shank drill chucks on drill presses, lathes, and hand drills requiring an 82-degree countersink geometry.

Installation Notes

This tool is installed by machinists or maintenance trades using standard drill chuck equipment. Secure the workpiece firmly before operation and ensure the spindle speed is appropriate for the material being countersunk — HSS tooling generally requires lower speeds in harder materials. No pilot is included; center the countersink over an existing clearance hole to prevent walking. Inspect the cutting edges before each use and do not force the tool if deflection or chatter is present.
