Value Collection SC1060040 Countersink 60 Deg 1 Flute Hss

Product Description

The VALUE COLLECTION SC1060040 is a single-flute, high-speed steel countersink designed for creating clean, accurate countersunk holes in metal and other materials. It features a 60-degree included angle with a 30-degree centerline angle, a 5/8-inch head diameter, and a 1/2-inch straight cylindrical shank for secure chuck mounting. The bright, uncoated finish suits general-purpose countersinking applications. This tool is suited for machinists, maintenance technicians, and fabricators working with drill presses, milling machines, or hand-held power tools where precise seat geometry is required.

This countersink is intended for countersinking operations in machine shops, fabrication facilities, and maintenance environments. The 60-degree included angle is commonly used for deburring, chamfering, and seating flat-head fasteners in metal workpieces. The single-flute design reduces chatter and produces a smooth finish on the countersunk seat. It is well-suited for both ferrous and non-ferrous materials in light to medium-duty production or repair work.

Key Features

• 60-degree included angle for standard flat-head fastener seating and chamfering
• Single-flute geometry minimizes chatter and improves surface finish quality
• High-speed steel construction provides durability in general-purpose cutting applications
• 1/2-inch straight cylindrical shank fits standard drill chucks and collet holders
• Bright, uncoated finish suitable for use with cutting fluids or dry cutting
• No pilot included — positions freely for flexible countersink placement

Compatibility

Designed as a general-purpose countersink compatible with drill presses, milling machines, and power drills equipped with a standard 1/2-inch or larger chuck or collet system.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Always secure the workpiece firmly before operation and ensure the shank is fully seated and tightened in the chuck or collet before running the tool. Use appropriate cutting fluid or coolant when working with harder metals to extend tool life. Follow all applicable shop safety standards and machine guarding requirements during operation.
