Value Collection SC3060040 Countersink 60 Degree 4 Flute Hss

Product Description

The VALUE COLLECTION SC3060040 is a single-end, 4-flute countersink designed for deburring, chamfering, and countersinking operations in metal and similar materials. Built from high-speed steel (HSS) with a bright uncoated finish, it delivers reliable cutting performance for general-purpose shop use. The 60-degree included angle produces a standard countersink profile suitable for flat-head fastener seating. The 1/2-inch straight-cylindrical shank fits standard drill chucks and collet holders commonly found on drill presses, CNC machines, and hand drills. Installation and use require no pilot, making it a straightforward tool for machinists, tool-and-die tradespeople, and maintenance technicians.

This countersink is suited for light to moderate production work where standard 60-degree chamfers are required on drilled holes. The 5/8-inch head diameter handles a practical range of hole sizes for fastener prep work. The 2-1/4-inch shank length provides adequate reach for most benchtop and machine-tool setups. It is a single-end tool, meaning the cutting geometry is on one end only, which is the standard configuration for machine-mounted countersinking operations in fabrication and maintenance environments.

Key Features

• 60-degree included angle for standard flat-head fastener countersinking
• 4-flute cutting geometry for smooth, consistent material removal
• High-speed steel construction for durability in general metalworking applications
• 1/2-inch straight-cylindrical shank compatible with standard drill chucks and collets
• Bright uncoated finish suitable for use with cutting fluids
• No-pilot design for straightforward setup and operation

Compatibility

Designed for use with drill presses, milling machines, and hand-held power drills equipped with a 1/2-inch or larger chuck or collet system. Suitable for countersinking operations in steel, aluminum, and similar machinable materials.

Installation Notes

Secure the 1/2-inch shank firmly in a properly sized drill chuck or collet before operation. Ensure the workpiece is clamped securely to prevent movement during the countersinking operation. Use an appropriate cutting fluid or lubricant when working with harder metals to prolong tool life. Inspect the cutting flutes for wear or damage before each use and replace the tool if chipping or dullness is observed.
