Cleveland C46124 Countersink 3/4 in 60 Degree Hss

Product Description

The CLEVELAND C46124 is a single-flute, high speed steel countersink designed for creating precise conical seat angles in metalworking applications. With a 3/4-inch head diameter and a 60-degree included angle, this tool produces clean, accurate countersinks in carbon steel and cast iron workpieces. The 1/2-inch straight-cylindrical shank provides secure chuck retention in standard drill presses and milling machines. An oxide coating helps reduce friction and extend tool life during cutting operations. Licensed machinists, toolmakers, and maintenance technicians rely on this type of tool for deburring holes and seating flat-head fasteners flush with the work surface.

This countersink is suited for production and maintenance environments where carbon steel and cast iron are the primary materials. The single-flute design reduces chatter and produces a smoother finish compared to multi-flute alternatives, making it a practical choice for hand-fed drill press work or CNC countersinking operations requiring tight angular tolerances. It is commonly used in fabrication shops, machine shops, and industrial maintenance settings.

Key Features

• 3/4-inch head diameter with a 60-degree included angle for standard flat-head fastener seating
• Single-flute geometry reduces chatter and improves finish quality
• High speed steel construction provides durability across carbon steel and cast iron applications
• Oxide coating reduces friction and helps extend cutting edge life
• 1/2-inch straight-cylindrical shank for compatibility with standard drill chucks and collets
• Right-hand cutting direction for use with conventional clockwise-rotating spindles

Compatibility

Designed for countersinking operations in carbon steel and cast iron. Fits standard drill chucks and collets accepting a 1/2-inch straight shank.

Installation Notes

This tool is installed by machinists or toolmakers in drill press or milling machine chucks. Secure the shank fully in the chuck and confirm it is centered before powering the spindle. Use appropriate cutting fluid for the workpiece material to maximize tool life and finish quality. Always power down and de-energize the machine before changing tooling.
