High-Performance HSSCo8 NC-Spotting Drill for Precise Positioning
The HSSCo8 NC-Spotting Drill 90° Short Version is a well-thought-out solution for exact spotting and centering on CNC machines. Thanks to its short and rigid design without guide lands, the risk of drill deflection is minimized, ensuring high positional accuracy of the hole. Furthermore, the 90° point angle allows the centering hole to be made deep enough to simultaneously serve as a 90° chamfer once the main core hole is drilled. Manufactured from cobalt-alloyed high-speed steel (HSSCo8), this tool features high thermal resilience and offers practical tool life across a variety of metallic materials.

Applications
This NC spotting drill is specifically tailored for use in CNC-controlled milling and turning centers. The 90° point angle design opens up flexible application possibilities, as centering and chamfering can often be combined into a single operational step. The universal cutting edge geometry supports efficient workflows in unalloyed and alloyed structural steel, stainless steel, cast iron, as well as aluminum and other non-ferrous metals. The tool is ideally suited for series production where precise positional hole preparation is required.
Special features
The short version of the HSSCo8 spotting drill impresses with its exceptional stability, as the short overhang effectively suppresses vibrations. This leads to outstanding hole quality and protects the subsequent twist drill. The 8% cobalt alloy significantly increases hot hardness, ensuring reliable wear protection even during demanding machining tasks or brief temperature peaks. Additionally, the smooth cylindrical shank offers versatile compatibility with commercially available chucks and supports smooth tool changes.
