Value Collection SC2160132 Countersink 1-1/2 in 60 Deg 6 Flute

Product Description

The VALUE COLLECTION SC2160132 is a 6-flute cobalt steel countersink designed for creating conical seat holes in metal workpieces ahead of fastener installation. With a 1-1/2 inch head diameter and a 60-degree included angle, it produces clean, accurate chamfers suited to standard flat-head screw applications. The 3/4 inch straight-cylindrical shank seats securely in drill press or milling machine chucks. Cobalt steel construction provides added heat and wear resistance compared to standard high-speed steel, making it a practical choice when working harder alloys or in production environments where tooling sees sustained use. The bright, uncoated finish keeps the cutting geometry visible during inspection.

This countersink is intended for use in machine shop, fabrication, and maintenance repair operations where precise countersinking of metal is required. It is well suited to drill press, knee mill, and CNC spindle setups. The right-hand cutting direction is standard for the vast majority of rotary machine tool applications. Machinists, tool-and-die technicians, and general metalworking professionals will find this tool fits into common production and job-shop workflows without special toolholding requirements.

Key Features

• 1-1/2 inch head diameter for large-diameter countersink applications
• 60-degree included angle, standard for most flat-head fastener seating
• 6 flutes for improved chip evacuation and surface finish
• Cobalt steel construction offers enhanced heat and wear resistance over standard HSS
• 3/4 inch straight-cylindrical shank fits standard drill press and milling machine chucks
• Right-hand cut, bright uncoated finish, single end, no pilot included

Compatibility

Designed as a standard single-end countersink for use in drill press, milling machine, and CNC spindle setups accepting a 3/4 inch straight-cylindrical shank. Compatible with common machine tool chucks and collet systems sized for 3/4 inch shanks.

Installation Notes

This tool is installed and operated by machinists or metalworking technicians using standard machine tool practices. Secure the shank fully in the chuck or collet before operation and confirm runout is within acceptable limits for the application. Power down and de-energize the machine before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole quality.
