Aircraft Counterbore 11/16 in
The Cleveland 46900 is an aircraft-length counterbore made from high-speed steel with an interchangeable pilot. It is designed for precision countersinking in aerospace maintenance and general metalworking applications where controlled depth and clean finishes are required.
Suited for interchangeable pilot work
This tool suits technicians who need a single counterbore body that accepts different pilot sizes for varying hole diameters. It is not for users who require a fixed-pilot counterbore, a non-aircraft length variant, or a different cutting diameter than 11/16 in.
11/16 in cutting diameter
The 11/16 in diameter determines the size of the counterbore recess produced. Verify that this exact dimension matches the fastener head or specification for the job before purchasing.

Questions about this item
Does the 11/16 in counterbore generate noticeable heat during extended drilling sessions?
The high-speed steel construction dissipates heat effectively during prolonged use, and the aircraft-length design allows deeper cuts without excessive temperature buildup at the cutting edges.
What tool holder or chuck is required to run the 11/16 in counterbore?
A standard drill chuck or collet that accepts the counterbore shank diameter is needed; the interchangeable pilot mounts inside the counterbore body for quick pilot changes.
Will the 11/16 in counterbore work with older drill presses that have lower spindle speeds?
High-speed steel tolerates the slower speeds of vintage drill presses, and the interchangeable pilot lets you match existing pilot sizes already in your workshop.
