Eagle Cutting Tool CS-8750-82-6-I Hss Countersink 7/8 in

Product Description

The EAGLE CUTTING TOOL CS-8750-82-6-I is a 7/8 inch high-speed steel (HSS) countersink with a 6-flute design and an 82-degree included angle. It is used to cut clean, accurate countersink profiles in a wide range of materials, allowing fastener heads to sit flush with or below the work surface. The 6-flute geometry reduces chatter and produces a smoother finish compared to single- or three-flute alternatives. At 0.05 pounds, this is a compact, lightweight tool suited for bench drill presses, hand drills, and CNC drilling operations.

This countersink is appropriate for use in metalworking, woodworking, and general fabrication environments where flush-mount fasteners are required. The 82-degree angle is the standard included angle for most imperial flat-head machine screws and sheet metal screws, making it a common choice in production and repair work across industrial and light manufacturing settings. It is typically used by machinists, fabricators, maintenance technicians, and skilled tradespeople working with drilled and tapped assemblies.

Key Features

• 7/8 inch cutting diameter for larger-diameter countersink profiles
• 82-degree included angle matches standard imperial flat-head fastener geometry
• 6-flute design minimizes chatter and improves surface finish
• High-speed steel (HSS) construction provides durability across a range of materials
• Lightweight at 0.05 pounds for easy handling and tool-changer compatibility

Compatibility

Designed as a standard 7/8 inch 82-degree HSS countersink suitable for use with common imperial flat-head fasteners in metalworking and general fabrication applications.

Installation Notes

This tool is installed in a drill chuck or collet compatible with its shank diameter. Secure the workpiece before operation and set spindle speed appropriate for the material being cut — lower speeds for harder metals, higher speeds for softer materials and wood. Always wear appropriate eye protection. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.
