Value Collection SC2082024 Countersink 82 Deg 6 Flute Hss

Product Description

The VALUE COLLECTION SC2082024 is a single-end, 6-flute countersink designed for creating clean, accurate 82-degree countersunk holes in metal and other materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it is suited for general-purpose countersinking in production and maintenance machining environments. The straight cylindrical shank measures 0.25 inches in diameter with a 1-inch shank length, and the head diameter is 0.375 inches. Right-hand cutting direction with a 41-degree centerline angle. No pilot is included. Machinists, tool-and-die workers, and maintenance technicians install this type of tool in drill presses, CNC machining centers, and hand drills.

This countersink is used for deburring drilled holes and seating flat-head fasteners flush with or below a workpiece surface. The 82-degree included angle matches the standard for imperial flat-head machine screws and is commonly applied in metal fabrication, MRO maintenance operations, and light manufacturing. The 6-flute geometry distributes cutting load evenly, reducing chatter on ferrous and non-ferrous workpieces. It is appropriate for both manual and machine-driven applications where a consistent countersink profile is required.

Key Features

• 82-degree included angle matches standard imperial flat-head fastener geometry
• 6-flute design reduces chatter and produces a smoother finish than single- or double-flute tools
• High-speed steel construction provides durability across ferrous and non-ferrous materials
• Bright uncoated finish allows visual wear inspection during use
• Straight cylindrical shank fits standard drill chucks and collet systems accepting 0.25-inch shanks
• Single-end, no-pilot design for straightforward chuck mounting and setup

Compatibility

Designed as an OEM-style countersink for use in any drill press, CNC machine, or handheld drill accepting a 0.25-inch straight cylindrical shank. Compatible with standard 82-degree flat-head fastener applications.

Installation Notes

A licensed machinist or trained technician should secure the shank fully in the chuck or collet before operation. Ensure the spindle is at a complete stop before changing or adjusting the tool. Use appropriate cutting fluid or lubricant when countersinking steel to extend tool life. Always wear appropriate eye protection and follow applicable shop safety procedures.
