Value Collection SC3060100 Countersink 60 Degree 4 Flute Hss

Product Description

The VALUE COLLECTION SC3060100 is a 4-flute high-speed steel countersink designed for precision chamfering and countersinking operations in metal fabrication and machining applications. With a 60-degree included angle and a 1-inch head diameter, this tool produces clean, accurate seat profiles for flat-head fasteners. The bright, uncoated finish makes it suitable for use on a range of common workpiece materials. The straight cylindrical shank measures 0.5 inches in diameter and 2.25 inches in length, providing secure chuck engagement on standard drill presses and milling setups. Machinists and tool and die professionals are the primary users of this style of countersink.

This countersink is suited for single-end countersinking operations in production and maintenance machining environments. The right-hand cutting direction is standard for conventional drill press and CNC spindle operation. The 60-degree angle is a common specification for metric and specialty fastener seating as well as center-drilling preparation. This tool does not include a pilot and does not feature a countersink head-only design, making it a standalone cutting tool intended for direct chuck mounting.

Key Features

• 60-degree included angle (30-degree centerline angle) for precise fastener seat geometry
• 4-flute design provides balanced cutting action and improved finish quality
• High-speed steel construction offers durability across a range of common workpiece materials
• Bright uncoated finish for general-purpose countersinking without specialized coating requirements
• 0.5-inch straight cylindrical shank for compatibility with standard drill press and milling chucks
• Single-end tool with no pilot, designed for direct chuck mounting

Compatibility

Designed as a general-purpose countersink for use in standard drill press, milling machine, or CNC spindle setups accepting a 0.5-inch straight cylindrical shank.

Installation Notes

Installation and use of this countersink should be performed by qualified machinists or tooling professionals. Secure the shank fully in the chuck and verify concentricity before operation. Always power down and lock out the machine before changing tooling. Set spindle speed appropriate to the workpiece material and tool diameter per standard machining practice before engaging the cut.
