The Tschorn 2D edge finder Model 001822500 for gun-drilling machines is a high-precision tool designed for quick and accurate determination of the workpiece position in deep-hole drilling operations. Made in Germany by Tschorn GmbH, this edge finder features an innovative construction specifically optimized for use on gun-drilling machines. The shank and the probe head are engineered to allow smooth insertion into the drilling bush or spindle, enabling the tool to move past the workpiece even when the space between the drilling bush and the part is extremely tight. This makes it ideal for applications where precise positioning is required in confined areas. The integrated LED probe signal offers excellent visibility thanks to additional shining-through holes and an all-around light design, ensuring the red LED can be clearly seen even when access is limited. The LED lights up instantly when the probing ball touches an electrically conductive workpiece, drastically reducing setup time compared to traditional edge-finding methods. For added protection, the probing ball is spring-mounted, providing mechanical safety against overrun in both X and Y axes. The edge finder is available with an Ø25mm shank and can be clamped directly into the drilling bush or spindle without adapters. This makes it a reliable and efficient solution for a wide range of high-precision industries, including aerospace, automotive, mold and die making, medical technology, precision engineering, and the firearms sector. The Tschorn edge finder is a professional-grade tool that combines German engineering, robust construction, and advanced functionality for demanding gun-drilling operations.
