Value Collection SC1082116 Countersink 82 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION SC1082116 is a single-flute, high-speed steel countersink designed for deburring and countersinking operations in metal and general-purpose machining applications. Built with an 82-degree included angle, it conforms to standard flat-head fastener geometry used across most production and maintenance environments. The 1-1/4 inch head diameter provides consistent material removal, while the 3/4 inch straight-cylindrical shank seats securely in standard drill chucks and collet holders. The bright, uncoated finish suits a wide range of ferrous and non-ferrous workpieces. This tool is installed and operated by machinists, tool-and-die workers, and maintenance technicians working with drill presses, CNC machining centers, or hand-held power tools.

The SC1082116 countersink is suited for right-hand cutting in single-pass countersinking operations on flat or low-profile surfaces. The single-flute design reduces chatter and produces a cleaner seat compared to multi-flute options in interrupted or hand-fed applications. It does not include a pilot, making it compatible with pre-drilled pilot holes sized to the fastener specification. Typical use cases include countersinking for flat-head machine screws, sheet metal assemblies, and structural fabrication work requiring flush fastener seating. This tool does not function as a drill and is intended for countersinking only.

Key Features

• 82-degree included angle matches standard flat-head fastener geometry
• Single flute reduces chatter and improves surface finish in hand-fed operations
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• 3/4 inch straight-cylindrical shank fits standard drill chucks and collet holders
• 1-1/4 inch head diameter for consistent countersink seat formation
• Bright uncoated finish — no pilot included, requires pre-drilled hole

Compatibility

Designed as an OEM-style replacement or standard supply countersink for use in drill presses, CNC machining centers, and hand-held power tools accepting a 3/4 inch straight-cylindrical shank. No specific model compatibility data was provided by the manufacturer.

Installation Notes

Installation is performed by machinists or maintenance technicians. Ensure the machine spindle is fully stopped and power is off before inserting or removing the tool from the chuck or collet. Secure the 3/4 inch shank fully within the chuck jaws or collet to the recommended engagement depth for the toolholder being used. Always pre-drill a pilot hole to the appropriate fastener diameter before countersinking — do not use this tool as a drill. Operate at speeds appropriate for the workpiece material and tool diameter per standard machining reference tables.
