Value Collection SC1082100 Countersink 82 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION SC1082100 is a single-flute, high-speed steel countersink designed for creating conical seat recesses in metal and other hard materials. Built with an 82-degree included angle and a 1-inch head diameter, this tool produces clean, accurate countersinks for flat-head fastener applications. The straight cylindrical shank measures 0.5 inches in diameter for secure chuck retention. The bright, uncoated finish suits general-purpose countersinking where coating is not required. This tool is installed and operated by machinists, tool and die workers, and maintenance professionals using standard drill presses or hand-held drilling equipment.

This countersink is suited for single-end countersinking operations in shop and field environments. The 82-degree included angle matches the standard American flat-head screw seat geometry, making it appropriate for preparing holes to accept 82-degree flat-head fasteners in metal fabrication, maintenance, and general machining work. The right-hand cutting direction is compatible with conventional clockwise spindle rotation on standard drill presses, milling machines, and hand drills. No pilot is included, so a pre-drilled guide hole or steady hand technique is required for accurate centering.

Compatibility

Designed as a general-purpose OEM-style countersink for use with standard drill presses, milling machines, and hand drills accepting a 0.5-inch straight cylindrical shank.

Installation Notes

This tool is typically operated by machinists or maintenance technicians using a drill press, milling machine, or hand drill. Secure the shank firmly in the chuck before operation and verify spindle rotation is set to right-hand (clockwise) before engaging the workpiece. Clamp the workpiece securely to prevent movement during countersinking. Follow applicable shop safety standards and wear appropriate eye protection when operating rotary cutting tools.
