Cleveland C00973 Countersink Set 5 Pc 82 Degree Hss

Product Description

The CLEVELAND C00973 is a 5-piece high speed steel countersink set covering head diameters from 1/4 inch to 3/4 inch with a consistent 82-degree included angle across all five tools. Each countersink features a 3-flute, right-hand cutting geometry and a straight shank ranging from 4.76 mm to 3/8 inch in diameter. Overall lengths run from 1.5 inches to 2.63 inches. The bright, uncoated finish is standard for general-purpose HSS tooling. This set is suited for machinists, fabricators, and maintenance technicians working with carbon steel and cast iron in production or shop environments.

This countersink set is designed for countersinking operations in carbon steel and cast iron workpieces. The 82-degree angle matches the standard fastener head geometry common in machine screw and bolt applications. With five graduated sizes in one case, this set covers a range of hole prep tasks without tool changes between common fastener sizes. It is a practical addition to any machine shop, fabrication facility, or tool crib stocking HSS cutting tools for ferrous material applications.

Installation Notes

Installation and use of this tool set is performed by machinists or skilled fabricators using drill presses, milling machines, or hand drills.
