Value Collection SC1060020 Countersink 60 Degree Hss

Product Description

The VALUE COLLECTION SC1060020 is a single-flute, high-speed steel countersink designed for creating clean, accurately angled seat recesses in metal and similar materials. Built with a 60-degree included angle and a 30-degree centerline angle, it cuts in a right-hand direction and is suited for precision countersinking work in machining and fabrication environments. The 1/4-inch straight-cylindrical shank fits standard drill chucks and collet holders. The bright, uncoated finish keeps the tool ready to run as delivered, without additional prep. This tool is typically handled by machinists, tool-and-die professionals, and skilled fabricators.

This countersink is intended for countersinking applications where a 60-degree seat angle is required. The single-flute geometry reduces chatter and produces a smooth finish in the recess. The 5/16-inch head diameter and 1/4-inch shank make it suitable for smaller fastener seat preparation in light machining setups. It does not include a pilot and is not a countersink head only — it is a complete, single-end tool ready for use in a drill press, milling machine, or hand drill with an appropriate chuck.

Key Features

• 60-degree included angle for standard fastener seat preparation
• Single-flute design reduces chatter and promotes smooth cutting
• High-speed steel construction provides good wear resistance for general machining
• 1/4-inch straight-cylindrical shank fits common drill chucks and collets
• 5/16-inch head diameter suited for smaller fastener applications
• Bright, uncoated finish — no additional prep required before use

Compatibility

Designed for use with standard drill presses, milling machines, or hand drills equipped with a chuck or collet accepting a 1/4-inch straight shank, in applications requiring a 60-degree countersink seat angle.

Installation Notes

Secure the 1/4-inch shank firmly in the chuck or collet before operation and verify there is no runout before cutting. Power down the machine completely before changing or adjusting the tool. Use appropriate cutting speeds for the workpiece material — excessive speed can reduce tool life in high-speed steel tooling. Follow applicable shop safety practices and wear proper eye protection during operation.
