It features a 118-degree drill point, a fast spiral flute design with a 35-degree helix angle, and a tapered web configuration. The right-hand cutting geometry and bright polished finish make it well suited for precision drilling in tight-tolerance applications. With a flute length of 0.625 inches (15.88 mm) and an overall length of 1.5 inches (38.10 mm), this bit is built for controlled, accurate penetration in materials where bit deflection or breakage is a concern.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in circuit board fabrication and similar precision drilling operations. It is appropriate for cutting cast iron, non-ferrous metals, and steel. The solid carbide construction supports use in CNC drilling equipment and high-speed spindle applications where rigidity and runout control are critical. It is used by machinists, PCB fabricators, and precision metalworking shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 40 wire size, 0.098 inches (2.49 mm) diameter for precision small-hole drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree drill point angle for general-purpose entry across multiple materials\u003c\/li\u003e\n  \u003cli\u003eFast spiral flute with 35-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eTapered web for improved drill point stability and reduced walking\u003c\/li\u003e\n  \u003cli\u003eBright polished finish, right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in circuit board drilling and precision small-hole applications involving cast iron, non-ferrous metals, and steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists or CNC technicians using appropriate spindle tooling.
