Abstract
The invention is an apparatus and method for determining and identifying drill bit type in a simple manner that does not involve complex mathematical techniques. The invention utilizes a laser scanner that produces a plurality of crosswise diameter measurements taken equidistantly along each drill bit's length. The crosswise measurement indicates the diameter of the bit's silhouette at a given location. By comparing such diameters with what would be expected for a given bit, the bit's shank type, maximum diameter, flute characteristics and length can be accurately ascertained. Having such information enables identification of the bit so that it may be later kept track of during subsequent sorting and refurbishment operations.
