5/16 X 11/32" High Speed Steel 3 Flute Solid Pilot Counterbore
Overall length is 5".
Cutter diameter is 1/2".
Shank diameter is 7/16".
Cap Screw is 5/16".
Pilot Diameter is 11/32".
Continuous pilot counterbores cut rapidly, smoothly and accurately, producing long spiraling chips rather than small metal particles.
The pilot extends the full length of the flute portion of the tool.
As cutter flutes are ground back due to wear, a new section of pilot becomes exposed.
The pilot head may be cut off to any desired length when repeated sharpening makes it too long for practical use.
Continuous pilot counterbores have a life many times that of the conventional type counterbore.
