Titan Tool Supply, Inc. Optical Drill Geometry Analyzer OTWD

The Optical Drill Geometry Analyzer is an inexpensive optical instrument available for checking of proper twist drill re-sharpening. Whether this is done free hand on a fixture or on a more expensive drill sharpening machine, industry lacks a quick and easy way of checking the results. What happens so often is that an improperly sharpened drill is used which results in incorrect hole diameter, poor drill control and excessive breakage. This comes about because the twist drill is a complex cutting tool designed to concurrently perform several functions. They are to penetrate directly into solid material, eject the chips outside the cutting area, maintain the straight direction of the advance movement of the drill, while controlling the hole diameter. The geometry necessary to perform these multiple of functions is designed into the basic new twist drill, but often lost due to improper re-sharpening. The optical drill analyzer is an inexpensive, simple, portable tool designed to check and maintain the four basic points of drill geometry. It is a necessary tool in every machine shop, tool room drill and cutter grinding department as well as tool cribs for checking the drills on hand.
