Cleveland C46135 Countersink 1 in 120 Deg Hss Right Hand

Product Description

The CLEVELAND C46135 is a single-flute countersink designed for creating accurately angled seat profiles in ferrous materials. Built from high speed steel (HSS) with an oxide finish for reduced friction and improved chip flow, this tool features a 1 inch head diameter and a 120-degree included angle, which corresponds to a 60-degree centerline angle. The straight-cylindrical shank measures 0.5 inches in diameter, making it compatible with standard drill chucks and milling setups. No pilot is included, and the end type is single. Licensed tradespeople in machining, fabrication, and industrial maintenance are the primary installers of this tooling.

The C46135 is suited for countersinking operations in carbon steel and cast iron workpieces. Its right hand cutting direction and single-flute geometry make it effective in applications where clean entry angles are required for fastener seating, deburring, or chamfering operations. The oxide surface treatment provides a mild level of lubricity and corrosion resistance appropriate for general shop use. This tool is sold individually and is intended for use in both production and maintenance environments.

Installation Notes

This tool is installed and operated by machinists, tool and die makers, or skilled maintenance technicians. Always secure the workpiece before beginning a countersinking operation, and confirm the machine is powered down and locked out before changing tooling. Use appropriate cutting fluid or lubricant for the material being machined to extend tool life. Follow applicable shop safety standards and equipment manufacturer guidelines for speed and feed settings.
