CrazyDrill SST-Inox is a solid carbide drill that exhibits a high degree of process reliability, long tool life and quick machining time when drilling holes in stainless, acid-resistant and heat-resistant steel as well as copper and lead-free brass. Consequently, the drill is used very successfully in many micro-precision applications (for example on micro milling machines) such as the watch industry, medical technology, implants, automotive engineering, injection technology, food industry, die making, mechanical engineering, dental technology, aviation industry, hydraulics, fittings, electronics and electrical engineering.
