Built to Series 559 standards and conforming to DIN 1897, this bit features a 135-degree split point that reduces walking and allows faster penetration without a center punch. The cobalt construction — M42 material grade — provides heat resistance and edge retention when drilling cast iron, steel, and other hard workpiece materials. At 7.00 mm in diameter and 3.02 inches overall length, it is sized for compact, short-reach drilling applications where stub or screw machine length tooling is required. A straw oxide finish adds additional surface protection. Installation is performed by machinists, fabricators, and maintenance technicians working with drill presses, CNC equipment, or hand-held power tools.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in ferrous metalworking applications, including production drilling in cast iron and steel. The screw machine length format — shorter than jobber-length bits — provides increased rigidity and reduced deflection in close-tolerance work. The 2-flute regular spiral design with a 4xD flute-to-diameter ratio supports efficient chip evacuation. It is well suited to repetitive hole patterns in manufacturing, maintenance repair, and general machine shop environments where dimensional accuracy and bit longevity are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for heat resistance and extended tool life in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement on most surfaces\u003c\/li\u003e\n  \u003cli\u003eScrew machine length format (3.02 inches OAL) provides rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraw oxide finish on cutting tip adds surface protection against wear and corrosion\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks without modification\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1897 specification and ISO standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a 7.00 mm screw machine length cobalt bit in the 6.50 to 8.00 mm diameter range.
