Features

Counterboring is the enlargement of a portion of a hole that has previously been formed
If the counterbored portion is shallow (1/8 in or less), the operations is usually known as spot facing for example, a flat seat for a bolt head or nut
If, on the other hand, the hole is enlarged to a considerable depth, it is designated as counterboring
These counterbores are made of 2-piece construction, having an integral shank and counterbore cutter and a pilot that is interchangeable, which provides flexibility in the use of the tool
