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.

alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- coolant
coolant
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
- stainless steels
stainless steels
Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.
