Eagle Cutting Tool CR-6250-82-I 82 Deg 3 Flute Hss Countersink

Product Description

The EAGLE CUTTING TOOL CR-6250-82-I is a high-speed steel (HSS) countersink and center reamer designed for precise 82-degree countersinking in metalworking and fabrication applications. With a 5/8-inch cutting diameter and a 3/8-inch shank, this 3-flute imperial tool delivers clean, accurate countersunk seats for flat-head fasteners in steel, aluminum, and similar materials. The 82-degree included angle matches the standard imperial flat-head screw geometry, making it a practical choice for production and maintenance environments where consistent results are required.

This countersink reamer is suited for use in drill presses, milling machines, and hand-held power tools equipped with a compatible 3/8-inch chuck. It is commonly used by machinists, maintenance technicians, and fabricators working on sheet metal, structural components, and general metalwork where imperial-standard countersunk holes are specified. The 3-flute design reduces chatter and promotes smoother cutting action compared to single-flute alternatives.

Key Features
