Value Collection SC2160016 Countersink 1/4 in 60 Deg 6 Flute

Product Description

The VALUE COLLECTION SC2160016 is a single-end cobalt steel countersink designed for deburring and chamfering operations on metal and hard materials. It features a 1/4-inch head diameter, a 60-degree included angle, and six flutes for smooth, efficient material removal. The straight-cylindrical shank measures 1/4 inch in diameter for secure chuck retention. The bright, uncoated finish preserves the cobalt steel substrate, offering good heat and wear resistance without an additional coating layer. This tool is well suited for machinists, toolmakers, and fabricators working in shop or field environments where consistent countersink geometry is required.

This countersink is intended for countersinking applications in metal fabrication, maintenance repair, and general machining work. The 60-degree included angle is commonly used for chamfering fastener seats and deburring drilled holes in steel, stainless steel, and similar ferrous materials. The right-hand cut direction is compatible with standard drill presses, CNC machines, and hand-held electric drills operating in conventional rotation. No pilot is included, making it a standard free-cutting countersink suitable for hand-fed or machine-fed operations.

Key Features

• 1/4-inch head diameter with a 60-degree included angle for consistent chamfer geometry
• Six-flute design promotes smooth cutting action and reduces chatter on hard materials
• Cobalt steel construction provides elevated heat resistance for drilling and countersinking in ferrous metals
• Right-hand cut direction compatible with standard drill rotation
• Straight-cylindrical 1/4-inch shank fits common chuck sizes on drill presses and hand drills
• Bright, uncoated finish — no additional coating to alter dimensional tolerances

Compatibility

Designed as an OEM-style single-end countersink for use in standard 1/4-inch or larger chucks on drill presses, hand drills, and CNC machines performing countersinking operations on metal workpieces.

Installation Notes

Install in a compatible 1/4-inch or larger keyed or keyless chuck, ensuring the shank is fully seated and securely tightened before operation. Power down and de-energize the machine before changing tooling. Use appropriate cutting fluid or coolant when countersinking hard ferrous alloys to extend tool life. Eye protection and proper workholding are required during all machining operations.
