Value Collection SC2082056 Countersink 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2082056 is a single-end, 6-flute countersink designed for right-hand cutting in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright/uncoated finish, it delivers consistent material removal when creating conical seat profiles for flat-head fasteners. The 82-degree included angle (41-degree centerline angle) matches the standard for inch-series flat-head screws. The straight cylindrical shank measures 0.5 inches in diameter and 1.3125 inches in length, fitting standard drill chucks and collet holders. Weight is 0.06 pounds. No pilot is included, making it suited for use in drill press or CNC setups where work-holding provides alignment.

This countersink is used in general machining, metal fabrication, and assembly operations where a clean, accurate 82-degree conical recess is required. It is appropriate for use on ferrous and non-ferrous metals in both job-shop and production environments. The 6-flute geometry reduces chatter compared to fewer-flute designs and produces a smoother finish in the countersunk recess. Machinists, tool-and-die makers, and maintenance technicians commonly deploy this tool for deburring drilled holes and seating flat-head fasteners flush with a workpiece surface.

Key Features

• 82-degree included angle matches the standard profile for inch-series flat-head screws
• 6-flute design minimizes chatter and improves finish quality in the countersunk seat
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• Bright/uncoated finish for general-purpose use without added coating cost
• Straight cylindrical shank fits standard drill chucks and collet holders
• Single-end, no-pilot configuration for use with guided fixturing or CNC setups

Compatibility

Designed as a general-purpose countersink for use in drill presses, milling machines, and CNC machining centers equipped with a standard chuck or collet accepting a 0.5-inch straight shank.

Installation Notes

Installation and use of this tool should be performed by a qualified machinist or trained technician. Secure the shank fully in the chuck or collet before starting the spindle, and confirm the workpiece is firmly clamped before cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Always wear appropriate PPE, including eye protection, when operating rotating cutting tools.
