Value Collection SC2190200 Countersink 2 in 6 Flute Cobalt

Product Description

The VALUE COLLECTION SC2190200 is a single-end, multi-flute countersink designed for producing clean, accurate countersunk holes in a wide range of materials. Built from cobalt steel with a bright, uncoated finish, this tool delivers the heat and wear resistance needed for demanding drilling applications. It features a 2-inch head diameter, a 90-degree included angle, a 45-degree centerline angle, and six flutes that produce a smooth seat for flat-head fasteners. The 1-inch straight-cylindrical shank is sized for secure clamping in a standard drill press, milling machine, or hand drill chuck. Machinists, tool and die workers, and fabrication professionals are the primary users of this tool.

This countersink is suited for production and job-shop environments where consistent countersunk seat geometry is required. The 90-degree included angle is the standard angle for most inch-system flat-head screws and bolts, making this tool appropriate for general metalworking, structural fabrication, and machine assembly applications. The six-flute configuration reduces chatter and improves surface finish compared to single- or three-flute designs, particularly in softer metals and non-ferrous alloys.

Key Features

• 2-inch head diameter provides broad countersink coverage for large fastener seats
• 90-degree included angle matches standard inch-system flat-head fastener geometry
• Six flutes reduce chatter and improve surface finish quality
• Cobalt steel construction offers superior heat and wear resistance over standard high-speed steel
• Bright, uncoated finish suitable for use with cutting fluid on a wide range of materials
• 1-inch straight-cylindrical shank fits standard toolholders and drill chucks
• Single-end design with no pilot — compatible with through-hole and blind-hole applications

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and hand drills equipped with a chuck or toolholder accepting a 1-inch straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists and metal fabricators following standard shop safety practices. Secure the shank fully in the chuck or toolholder before operation and verify the workpiece is clamped or fixtured to prevent movement. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.
