Introduction

Today, with the all-round development of the manufacturing industry and its all-round development, in order to have a complete and accurate product, very accurate tools are needed throughout the entire manufacturing process. Therefore, the ultra-precise tool of the optical index mandrel provides the possibility for the user to perform one of the most important parts of production, which is drilling, with accuracy (0.07 mm) very easily and conveniently. Product: Before drilling, it is necessary to mandrel to prevent the movement of the drill head when drilling. First, insert the optical lens into the guide bush and move the bush and the lens to the previously determined point so that the position of the center of the bush corresponds to the exact point of the hole. Then hold the bush with one hand and remove the lens with the other hand. Remove the mandrel and place it in the bush and hit the mandrel with a hammer while maintaining the original position of the bush, thus completing the marking stage.
This product has been designed and produced in two models, one with LED and the other without LED. It should be noted that one of the important tasks of the optical lens is to bring enough light to the aiming center. However, the LED model is intended for low-light environments.

xNote: Do not touch the separate optical lens with sharp objects or rough surfaces.
