Cleveland C46115 Countersink 1/2 in 90 Deg Hss Right Hand

Product Description

The CLEVELAND C46115 is a single-flute high speed steel countersink designed for creating accurately angled seat profiles in ferrous workpieces. It features a 1/2 inch head diameter and a 90-degree included angle, producing a 45-degree centerline angle at the cutting edge. The 1/4 inch straight cylindrical shank fits standard drill chucks and collet holders. An oxide coating provides basic lubricity and corrosion resistance during cutting operations. This tool is installed and operated by machinists, fabricators, and maintenance technicians working on carbon steel and cast iron components.

The C46115 is suited for countersinking fastener seats, chamfering hole entries, and deburring drilled holes in carbon steel and cast iron workpieces. Its single-flute geometry reduces chatter and improves surface finish in hand-held or machine-fed applications. The right-hand cutting direction is compatible with standard drill presses, CNC machining centers, and hand drills. This is a solid-body countersink with no pilot and a single end, making it a general-purpose tool for production and maintenance environments.

Key Features

Compatibility

Designed for use in carbon steel and cast iron applications. Compatible with standard drill presses, CNC machining centers, and hand-held drills accepting a 1/4 inch straight cylindrical shank.

Installation Notes

Secure the shank firmly in a drill chuck or collet before operation and confirm the workpiece is clamped or fixtured to prevent movement. Power down and de-energize the machine before changing tooling. Use appropriate cutting fluid or lubricant when countersinking steel to extend tool life and improve finish quality. Follow applicable shop safety standards and machine-specific operating procedures during use.
