Value Collection SC4060016 Countersink 60 Deg 3 Flute Hss

Product Description

The VALUE COLLECTION SC4060016 is a single-end, straight-shank countersink designed for metal fabrication and machining work. Built from high-speed steel with a bright uncoated finish, it cuts a 60-degree included angle with three flutes in a right-hand direction. The 1/4-inch head diameter and 3/16-inch straight cylindrical shank make it compatible with standard drill chucks and collet holders. This tool is suited for machinists, tool-and-die workers, and general metalworking shops that need consistent, clean countersunk holes for flat-head fastener seating.

This countersink is used in drill press, CNC, and hand-drill applications where a 60-degree countersink profile is required. The 3-flute geometry provides a balance between chip clearance and surface finish quality. It does not include a pilot, making it versatile for use across varying hole diameters within its head size range. Typical applications include deburring, chamfering, and fastener-seat preparation in steel, aluminum, and similar metals.

Key Features

Compatibility

Designed as an OEM-style single-end countersink for use in standard drill press, CNC, or hand-drill setups requiring a 60-degree countersink profile with a 3/16-inch straight cylindrical shank.

Installation Notes

This tool is installed and operated by machinists or skilled tradespeople familiar with rotating cutting tools. Secure the shank firmly in the chuck or collet before operation and confirm the workpiece is clamped to prevent movement. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life. Follow standard shop safety practices including eye protection and proper spindle speed selection for the material being cut.
