Value Collection CS2160032 Countersink 1/2 in 6 Flute Cobalt

Product Description

The VALUE COLLECTION CS2160032 is a single-end cobalt steel countersink designed for creating clean, accurately angled seat recesses in metal and hard materials. It features a 1/2 inch head diameter and an 82-degree included angle, making it suitable for flat-head fastener seating where precise angular control is required. The 6-flute design distributes cutting load evenly, reducing chatter and producing a smoother finish compared to fewer-flute designs. A 1/4 inch straight cylindrical shank provides secure, repeatable chuck engagement. The bright, uncoated finish is standard for cobalt-grade tooling used in ferrous and high-strength material applications. Machinists and tool-and-die tradespeople are the primary installers of this tool.

This countersink is used in machining, fabrication, and maintenance applications where flat-head screws or bolts must sit flush or below the workpiece surface. It is well suited for use in drill presses, CNC machining centers, and hand-held power tools with a standard 1/4 inch chuck or collet. Typical applications include metal plate work, structural fabrication, and precision assembly operations requiring consistent countersink geometry. The 82-degree included angle aligns with imperial flat-head fastener standards commonly found in general manufacturing and repair environments.

Key Features

• 1/2 inch head diameter with 82-degree included angle for imperial flat-head fastener seating
• 6-flute configuration reduces chatter and improves surface finish quality
• Cobalt steel construction provides heat and wear resistance in hard or abrasive materials
• 1/4 inch straight cylindrical shank fits standard chucks and collets
• Bright, uncoated finish — no coating buildup to interfere with tight-tolerance work
• Single-end design, no pilot included, for open-tolerance countersinking applications

Compatibility

Designed as a standard single-end countersink for use with 1/4 inch straight-shank chucks and collets in drill presses, CNC equipment, and portable power tools performing countersinking operations on metal and similar hard materials.

Installation Notes

Install and remove this tool only when the spindle is fully stopped and the machine is powered down. Secure the shank fully in the chuck or collet to the manufacturer-specified engagement depth before operation. Use appropriate cutting fluid or lubricant when working with hard ferrous metals to extend tool life. Wear appropriate PPE including eye protection when operating any rotary cutting tool.
