Value Collection SC3060048 Countersink 60 Deg 4 Flute Hss

Product Description

The VALUE COLLECTION SC3060048 is a 4-flute high-speed steel countersink designed for precision countersinking operations in metal fabrication, machining, and assembly work. Built with a 60-degree included angle and a bright uncoated finish, this tool delivers clean, consistent chamfered seats for flathead fasteners. The straight-cylindrical shank measures 1/2 inch in diameter with a shank length of 2-1/4 inches, making it compatible with standard drill chucks and collet holders. Right-hand cutting direction suits conventional CNC and manual drill press setups. At 0.5 pounds, it is a compact, practical tool for daily shop use.

This countersink is suited for use in machine shops, maintenance facilities, and fabrication environments handling metal workpieces. It is appropriate for both production and one-off countersinking tasks where a 60-degree seat angle is required for flathead screws or chamfered hole finishes. The 3/4-inch head diameter makes it effective on small-to-mid-range hole sizes. Machinists, tool-and-die workers, and maintenance technicians are the primary users in both job shop and industrial settings.

Key Features

• 60-degree included angle (30-degree centerline angle) for standard flathead fastener seating
• 4-flute design for smooth cutting action and reduced chatter
• High-speed steel construction for durability across a range of metal materials
• Bright/uncoated finish suitable for general-purpose machining applications
• 1/2-inch straight-cylindrical shank fits standard drill chucks and collet systems
• No pilot included — used as a standalone countersink without guide pin

Compatibility

Designed as an OEM-style replacement or standard countersink for use with any drill press, CNC machining center, or hand drill equipped with a 1/2-inch or larger chuck accepting a straight-cylindrical shank.

Installation Notes

This tool is installed by machinists and tool operators into a compatible drill chuck or collet holder. Ensure the machine spindle is fully powered down and locked out before inserting or removing the countersink. Set spindle speed appropriate to the workpiece material and tool diameter per standard machining reference charts. Secure the workpiece firmly before operation to prevent movement during cutting.
