Cleveland C46429 Counterbore Port Tool

The Cleveland C46429 is a counterbore port tool designed for machining operations requiring an interchangeable pilot. It is intended for professional machinists and maintenance technicians who need to create precise counterbores in various materials. The high-speed steel construction provides durability for repeated use in workshop environments.

4.063in Length and .375in Diameter Capacity

This tool measures 4.063 inches in overall length with a .375 inch body diameter. The high-speed steel material handles general-purpose counterboring in steel, cast iron, and non-ferrous alloys effectively. It reaches its limit when machining hardened materials exceeding the tool's hardness rating or when pilot sizes fall outside the interchangeable range.

Interchangeable Pilot System Flexibility

The counterbore accepts interchangeable pilots, allowing one tool body to accommodate multiple hole diameters. This reduces the number of individual tools required for varied counterbore sizes. The bright finish indicates an uncoated surface suitable for applications where coating buildup could affect pilot fit or where coolant compatibility is a concern.

Questions about this item

Will the Cleveland C46429 counterbore fit the 0.375in pilot I already use?

The cutter has a 0.375in diameter, so it accepts a pilot of that exact size for interchangeable use.

How can I confirm the Cleveland C46429 is cutting correctly after installation?

A clean, flat-bottomed counterbore at the full 4.063in length with no chatter indicates the high-speed steel tool is performing properly.

Does the Cleveland C46429 package include the interchangeable pilot or must I buy it separately?

Only the counterbore body is supplied; the interchangeable 7/16in pilot is not included and must be purchased separately.
