Cleveland C46119 Countersink 5/8 in 60 Degree Single Flute Hss

Product Description

The CLEVELAND C46119 is a single-flute high speed steel countersink designed for deburring and seat-forming operations in metalworking applications. It features a 5/8 inch head diameter and a 60-degree included angle, making it suited for work where a shallow, wide countersink profile is required. The 3/8 inch straight cylindrical shank fits standard drill chucks and collet holders. A black oxide coating provides mild corrosion resistance and reduces friction during cutting. Machinists, tool and die workers, and fabrication shop technicians are the primary users of this tool.

This countersink is intended for use on carbon steel and cast iron workpieces. It is suited for bench drill press work, CNC drilling centers, and manual milling setups where a single-flute geometry is preferred for chatter reduction on softer ferrous materials. The right-hand cutting direction is standard for conventional spindle rotation. It does not include a pilot, and the end type is single, meaning it is designed for countersinking only rather than combination drilling and countersinking operations.

Key Features

• 5/8 inch head diameter with 60-degree included angle for wide, shallow countersink geometry
• Single-flute design reduces chatter and improves surface finish on ferrous materials
• High speed steel construction provides durability across carbon steel and cast iron applications
• Black oxide coating offers mild corrosion resistance and reduces built-up edge during cutting
• 3/8 inch straight cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cut, no pilot, single end — straightforward drop-in use without additional tooling

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Fits any drill press, milling machine, or CNC spindle accepting a 3/8 inch straight shank tool holder.

Installation Notes

Install and remove this tool only when the spindle is fully stopped and the machine is powered off or locked out per your facility lockout/tagout procedure. Secure the shank firmly in the chuck or collet before running the spindle. Feed rate and spindle speed should be set per the material and tool manufacturer guidelines for high speed steel on ferrous stock. Inspect the cutting edge before each use and replace the tool if chipping or excessive wear is observed.
