Value Collection 152-2-100-.1562 Adjustable Stop Countersink

Product Description

The VALUE COLLECTION 152-2-100-.1562 is a 2-flute adjustable stop countersink designed for precision countersinking in metalworking and fabrication applications. Built from high speed steel (HSS) with a bright polished finish, it delivers clean, accurate countersunk holes for flathead fasteners. The tool features a 100-degree included angle, a 1/2-inch head diameter, and an overall length of 2.5 inches. An integral pilot keeps the cutter centered during operation, while the adjustable stop collar controls countersink depth consistently across repeated operations. The 1/4-28 straight threaded shank allows the stop mechanism to be set and locked at a precise depth, reducing manual measurement between holes.

This countersink is suited for production and maintenance environments where repeatable countersink depth is critical. Machinists, tool and die makers, and maintenance technicians use adjustable stop countersinks when drilling and countersinking flathead screw seats in steel, aluminum, and similar materials. The bright HSS construction is appropriate for general-purpose ferrous and non-ferrous metal applications at moderate cutting speeds.

Key Features

• Adjustable stop collar for repeatable, controlled countersink depth
• Integral pilot centers the cutter and prevents walking
• 2-flute geometry for smooth cutting action
• 100-degree included angle suits common flathead fastener geometries
• High speed steel construction with bright polished coating
• 1/4-28 straight threaded shank for secure stop adjustment

Compatibility

Designed as an OEM-style replacement or direct addition for drill presses, CNC machines, and hand drills accepting a 3/16-inch shank diameter countersink tool.

Installation Notes

This tool is installed and adjusted by machinists or maintenance technicians using standard toolholding equipment. Before mounting, ensure the machine spindle is fully powered down and locked out per applicable lockout/tagout procedures. Set the adjustable stop collar to the desired countersink depth and secure it firmly before beginning production runs. Use appropriate cutting fluid for the workpiece material to extend tool life.
