Cleveland C00972 Countersink Set 5 Pc 3 Flute Hss

Product Description

The CLEVELAND C00972 is a 5-piece high-speed steel countersink set designed for creating clean, accurate countersunk holes in carbon steel and cast iron workpieces. Each tool in the set features a 3-flute, single-end design with a 60-degree included angle and right-hand cutting direction. Head diameters range from 1/4 inch to 3/4 inch across the five pieces, with straight shanks ranging from 4.76 mm to 3/8 inch in diameter. Overall lengths span 1.5 inches to 2.63 inches. The bright, uncoated finish suits general-purpose shop use where coating is not required. The set ships in a plastic storage case.

This countersink set is suited for metalworking applications in production, maintenance, and repair environments. It is used to prepare holes for flat-head fasteners, deburr drilled openings, and chamfer edges in carbon steel and cast iron components. The range of head diameters makes the set practical for varying fastener sizes without requiring separate tools. It is a common addition to machine shop tooling, fabrication setups, and general metal trades where countersinking is a routine operation.

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Straight shank configuration fits standard drill press chucks, CNC machining centers, and hand-held drill drivers accepting the corresponding shank diameters.

Installation Notes

These countersinks are installed and removed by a machinist or metalworker using a standard chuck key or tool holder appropriate to the shank diameter. Secure the workpiece firmly before operation to prevent movement during cutting. Inspect each tool for wear or damage before use, and select the appropriate head diameter to match the fastener specification. Follow standard machine safety practices including the use of appropriate eye protection and cutting fluid where required by the material.
