BIG DAISHOWA Introduces Sphinx Drinox Pilot Step Drill Achieving 3×D Performance!
BIG DAISHOWA has expanded its precision holemaking portfolio with the launch of the Sphinx Drinox Pilot Step Drill at 3×D, a micro-drilling solution engineered to deliver significantly higher productivity, tool life, and process reliability in demanding materials. Designed for high-precision applications, the new pilot step drill is optimized to achieve up to three times longer tool life, three times higher coolant-through output, and three times faster drilling performance compared with conventional designs.
The Sphinx Drinox Pilot Step Drill is available in diameters ranging from 0.70 mm to 3.00 mm, with fine intermediate size increments of 0.05 mm, making it particularly suitable for applications that require tight tolerances and precise hole dimensions. This broad size availability allows manufacturers to select the exact tool diameter needed for precision components, reducing the need for secondary operations or corrective machining.
A key feature of the drill is its coolant-through design, which maximizes coolant delivery directly to the cutting edge. The enhanced coolant flow improves heat dissipation, supports efficient chip evacuation, and stabilizes the cutting process—critical factors when working with small diameters and challenging materials. By maintaining consistent cooling at the cutting zone, the tool helps prevent premature wear and reduces the risk of tool failure.
The drill is further enhanced by a newly developed TiSiN ultra-thin coating, which BIG DAISHOWA says maintains exceptional cutting-edge sharpness. This coating reduces friction, improves chip flow, and prevents material adhesion on the cutting edges. As a result, the Sphinx Drinox delivers smoother drilling action, cleaner holes, and more consistent performance over extended tool life, even in high-demand production environments.
From a geometric standpoint, the Sphinx Drinox features a 90-degree cutting step and tool head, based on the proven geometry of high-performance drilling tools. This design contributes to improved stability and accurate hole positioning, while also supporting faster penetration rates. The geometry performs particularly well in stainless steels, titanium, and heat-resistant nickel- or cobalt-based alloys, materials that are known for generating high cutting forces and heat during drilling.
By combining optimized geometry, advanced coating technology, and high-efficiency coolant delivery, the Sphinx Drinox Pilot Step Drill is well suited for precision industries such as aerospace, medical devices, electronics, and high-end mechanical engineering. Its ability to drill efficiently at 3×D depths with enhanced speed and durability makes it an attractive solution for manufacturers seeking higher productivity without compromising accuracy or tool reliability.
With the introduction of the Sphinx Drinox Pilot Step Drill, BIG DAISHOWA continues to focus on delivering high-performance, precision tooling solutions that help manufacturers push the limits of micro-drilling while maintaining consistent quality and process security.
