Cleveland C46447 Port Tool Overview
The Cleveland C46447 is a new high-speed steel port tool designed for counterboring operations with interchangeable pilots. It serves machinists and maintenance technicians who require a dedicated cutting accessory for creating precise counterbores in workshop applications. The bright finish indicates standard ground tooling ready for immediate use. This accessory fits into power and pneumatic tool setups for metalworking tasks.
Sustained Cutting Behaviour
High-speed steel construction allows the tool to maintain cutting geometry during extended counterboring cycles rather than dulling quickly in short bursts. The material resists heat buildup when fed steadily into ferrous workpieces, preserving the 0.750 inch diameter accuracy over repeated passes. Consistent lubrication and appropriate speed settings further support stable performance throughout a production run.
Interchangeable Pilot Constraints
The counterbore design relies on a separate pilot to locate the cut, meaning the tool cannot self-centre on an unprepared hole. Users must select and secure a pilot matching the existing bore diameter before machining begins. This dependency limits the tool to applications where a pilot hole already exists and a compatible pilot is available for the specific job.

Questions about this item
How much heat does the .750" diameter high-speed steel generate when running continuously in a pneumatic tool?
The high-speed steel construction resists heat buildup during extended use, but actual temperature depends on cutting speed, feed rate and coolant applied by the operator.
What shank size or holder does the 6.375" overall length require to mount in my machine?
The counterbore body accepts an interchangeable pilot; you must supply a pilot of the correct diameter and a tool holder that matches your machine spindle.
Will this 46447 counterbore work with pilots from my older Cleveland tooling set?
It is designed for interchangeable pilots; compatibility depends on the pilot shank diameter and retention style of your existing set.
