Applications
This spotting tool opens up flexible application possibilities in modern metal cutting. It is excellently suited for producing exact center holes prior to the actual drilling process. The 142-degree point angle safely guides the following drill and significantly reduces the risk of deflection. Its suitability for structural steel, case-hardening steel, stainless steels, cast iron, and aluminum alloys makes the spotting drill a practical choice in toolmaking and mechanical engineering.
Special features
The combination of a short design and a cylindrical shank supports efficient workflows through high rigidity and easy handling. By avoiding unnecessary length, the tendency to vibrate is minimized, which positively affects tool life and the quality of the spotting. The available diameters from 3 mm to 20 mm cover a broad spectrum of professional applications.
