The Sphinx Drinox Pilot Step Drill at 3xd from BIG DAISHOWA features a unique design that the company says delivers up to three times longer tool life, three times higher coolant-through output and three times faster drilling.

Available in diameters from 0.70 to 3.00 mm, with intermediate diameters in increments of 0.05 mm, the Sphinx Drinox features coolant-through channels to maximize the coolant output, and the newly developed TiSiN ultra-thin coating that the company says ensures high tool sharpness, improving chip removal and preventing material from sticking. In addition the tool design has a 90° cutting step and tool head, which are based on the geometry of proven high-performance tools and perform exceptionally well in stainless steels, titanium and heat-resistant Ni or Co alloys.
