Value Collection SC1082016 Countersink 82 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION SC1082016 is a single-flute countersink designed for creating beveled seat recesses in metal and other materials prior to fastener installation. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool operates with a right-hand cutting direction and mounts via a straight-cylindrical shank. The 82-degree included angle conforms to the standard fastener seat geometry used across a wide range of flat-head screw applications. With a 1/4-inch head diameter and 1/4-inch shank diameter, this countersink fits standard drill chuck setups commonly found in machine shops, fabrication environments, and field maintenance operations.

This countersink is suited for single-end countersinking operations where a clean, accurate bevel seat is required. It does not include a pilot and is intended for use in applications where the pilot hole is already established or where a pilotless approach is preferred. The single-flute design provides free cutting action and is well-suited for use in drill presses, CNC machines, and hand-held power drills in both production and maintenance settings. Machinists, fabricators, and general maintenance technicians are the typical end users for this style of tool.

Key Features

• 82-degree included angle matches standard flat-head fastener seat geometry
• Single-flute design promotes free cutting and chip clearance
• High-speed steel construction provides durability across common metals
• Bright, uncoated finish suits general-purpose countersinking applications
• Straight-cylindrical shank fits standard 1/4-inch drill chucks and collets
• No pilot included, allowing use where the pilot hole is pre-drilled

Compatibility

Designed as a general-purpose countersink for use with standard drill chucks and collets accepting a 1/4-inch straight shank, compatible with drill presses, CNC spindles, and hand-held power drills configured for countersinking operations.

Installation Notes

Install the shank securely into the drill chuck or collet before operation and confirm the workpiece is clamped or fixtured to prevent movement. Establish the pilot hole at the correct diameter before countersinking when a pilotless approach requires it. Apply consistent feed pressure and use an appropriate cutting speed for the workpiece material to avoid chatter or tool deflection. Inspect the countersink edge for wear after extended use, as a dull flute can cause an out-of-round seat.
