Value Collection SC4060048 Countersink 60 Degree 3 Flute

Product Description

The VALUE COLLECTION SC4060048 is a single-end, straight-shank countersink designed to produce clean, accurate 60-degree countersunk seats in metal workpieces. Machined from high-speed steel with a bright, uncoated finish, it features three flutes and a right-hand cutting direction. The 3/4-inch head diameter and 1/2-inch straight-cylindrical shank make it compatible with standard drill chucks and collet holders. This tool is suited for machinists, toolroom technicians, and maintenance professionals who need reliable countersinking performance on the bench or in a production environment.

This countersink is intended for countersinking applications in metal fabrication, maintenance repair, and general machining operations. The 60-degree included angle is commonly used for fastener seat preparation and deburring operations where a consistent chamfer is required. The straight-cylindrical shank seats securely in standard drill press chucks and milling machine collets, making it a straightforward choice for shop use. No pilot is included, so proper center alignment is the responsibility of the operator.

Key Features

• 60-degree included angle with a 30-degree centerline angle for standard countersink profiles
• Three flutes for balanced cutting action and chip clearance
• High-speed steel construction for durability across a range of metals
• Bright, uncoated finish — no coating to chip or peel
• 1/2-inch straight-cylindrical shank fits standard drill chucks and collet holders
• Single-end design with no pilot included

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and hand-held drill applications where a 1/2-inch straight-shank tool is accepted.

Installation Notes

This tool is typically installed by machinists or toolroom technicians in a drill press, milling machine, or hand drill with a compatible chuck or collet. Secure the shank fully in the chuck and verify runout before beginning the cut. Work at appropriate spindle speeds for the workpiece material — high-speed steel tools require lower speeds on harder materials to prevent heat buildup. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before operation.
