Value Collection SC2182040 Countersink 6 Flute Cobalt

Product Description

The VALUE COLLECTION SC2182040 is a single-end cobalt steel countersink designed for creating conical seat holes in metal and hard materials. With a 5/8 inch head diameter, an 82-degree included angle, and six flutes, this tool delivers smooth, chatter-resistant cuts in ferrous and non-ferrous metals. The straight cylindrical shank measures 1/2 inch in diameter, making it compatible with standard drill chucks and tool holders. It carries a bright, uncoated finish and is configured for right-hand cutting. This countersink is well suited for machinists, fabricators, and maintenance technicians working in production or job-shop environments.

This countersink is intended for countersinking fastener seats in steel, stainless steel, aluminum, and similar materials where an 82-degree flat-head screw seat is required. The cobalt steel construction handles harder workpiece materials and elevated cutting temperatures better than standard high-speed steel, making it a practical choice for production drilling, CNC setups, or manual drill press work. No pilot pin is included, so the tool self-centers in pre-drilled holes. It is sold as a single piece.

Key Features

• 5/8 inch head diameter with an 82-degree included angle for standard flat-head fastener seats
• Six flutes for smooth chip evacuation and reduced chatter on ferrous metals
• Cobalt steel construction resists heat buildup when cutting hardened or stainless materials
• 1/2 inch straight cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction, single-end design, no pilot included
• Bright uncoated finish — no coating buildup to affect dimensional accuracy

Compatibility

Designed for use in standard drill presses, CNC machining centers, and hand-held drills equipped with a 1/2 inch or larger chuck. Suitable for countersinking 82-degree flat-head fastener seats in steel, stainless steel, aluminum, and similar materials.

Installation Notes

Secure the 1/2 inch shank firmly in the chuck or collet before operation and verify runout is within acceptable limits. Use appropriate cutting fluid or lubricant when countersinking hardened or stainless steel to extend tool life. Power down and de-energize the machine spindle completely before changing or inspecting the tool. Follow applicable shop safety standards and wear proper eye protection during use.
