Cleveland C46439 Port Tool
The Cleveland C46439 is a high-speed steel port tool designed for counterboring operations with interchangeable pilots. It suits machinists and maintenance technicians preparing precise seats in metal components. The bright finish indicates an uncoated ground surface. This accessory fits standard tool holders used in pneumatic or powered machining setups.
Replaces worn counterbores
This tool replaces a dull or damaged counterbore when hole quality degrades or pilot fit becomes loose. The jump is worth it when the existing cutter no longer produces a clean, flat-bottom seat for the intended fastener or insert. High-speed steel construction allows resharpening, extending service life before a full replacement is required. It upgrades performance in repetitive porting tasks.
Limited to pilot compatibility
The cutter diameter of .500 inch and overall length of 5.375 inches define the reach and bore size this tool can produce. It only accepts pilots matched to the specific counterbore shank and pilot hole dimensions. The high-speed steel material limits cutting speed compared to carbide in abrasive or high-temperature alloys. Rigidity decreases with deeper cuts beyond the supported length.

Questions about this item
What size pilot does the 0.500 in. diameter port tool accept?
The cutter is designed for interchangeable pilots; the shank diameter is 0.500 in.
How is the high-speed steel counterbore secured in a machine spindle?
Clamp the 0.500 in. shank in a matching collet or chuck and tighten before engaging the workpiece.
When should the interchangeable pilot be replaced on this cutter?
Replace the pilot when its diameter wears undersize or the pilot shank shows visible scoring that affects concentricity.
