Value Collection SC2160012 Cobalt Countersink 3/16 in

Product Description

The VALUE COLLECTION SC2160012 is a single-end cobalt steel countersink designed for creating beveled recesses that allow flat or oval-head fasteners to sit flush with or below a workpiece surface. With a 3/16 inch head diameter and a 60-degree included angle, this tool is suited for light-duty countersinking in ferrous and non-ferrous materials. Six flutes provide smooth chip evacuation and a clean, finished seat. The straight-cylindrical shank measures 3/16 inch in diameter, making it compatible with standard drill chucks and quick-change holders. Right-hand cutting direction follows standard rotation for most drill presses and hand drills. No pilot is included. This countersink is typically installed by machinists, tool-and-die workers, metalworkers, and experienced tradespeople performing precision fastener prep work.

This countersink is suited for general countersinking applications in machine shops, fabrication environments, and maintenance settings. The cobalt steel construction offers improved heat and wear resistance compared to standard high-speed steel, making it a practical choice when working with harder materials or in higher-production scenarios. The single-end design keeps the tool compact and straightforward to deploy in standard rotating equipment. It is appropriate for use in both manual and machine-fed drilling setups where a 60-degree seat angle is required by the fastener specification.

Key Features

• 3/16 inch head diameter with a 60-degree included angle for standard flat-head fastener seating
• Six flutes for efficient chip removal and a clean countersunk finish
• Cobalt steel construction for enhanced heat resistance and extended tool life in harder materials
• Right-hand cut, matching standard drill rotation — no special setup required
• Straight-cylindrical 3/16 inch shank fits standard drill chucks and quick-change systems
• Single-end design with no pilot — provides flexibility for operator control of centering

Compatibility

Designed for use in standard drill presses, CNC machining centers, and hand drills with chuck capacity accommodating a 3/16 inch straight shank, wherever a 60-degree countersink is required by fastener specification.

Installation Notes

This countersink is installed and operated by machinists, fabricators, and skilled tradespeople using standard rotating equipment. Secure the straight shank firmly in the chuck before operation and verify that the workpiece is clamped or fixtured to prevent movement. Apply appropriate cutting fluid when working with harder ferrous materials to preserve tool life. Inspect the cutting edges before each use and remove the tool from service if chipping or wear is observed.
