Built to Series 559 specifications, it features a 135-degree split point and web-thinned geometry that reduces walking on entry and lowers thrust requirements. At 0.0625 inches (1\/16 inch) in diameter with a straight-cylindrical shank, this bit is suited for close-tolerance work where the M42 cobalt construction provides heat and wear resistance beyond standard high-speed steel. A two-flute regular spiral promotes efficient chip evacuation in ferrous materials. Licensed machinists, maintenance technicians, and industrial tradespeople are the primary users of this bit.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for production and maintenance drilling in ferrous workpieces, including cast iron and steel. The screw machine length body — shorter than a jobber-length bit — provides added rigidity and reduces deflection in drill press, CNC, and turret lathe applications. The right-hand spiral flute and split point geometry make it well suited for short-run and repetitive operations where dimensional accuracy and bit longevity matter. It meets ISO standards and carries a heavy-duty grade rating appropriate for demanding shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for extended tool life in hard and abrasive ferrous materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces drill walking and lowers feed force\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body increases rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, two-flute regular spiral for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.0000 to -0.0005 inches for close-tolerance hole work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use bit for standard drill chucks and collets accepting a 1\/16-inch straight-cylindrical shank, compatible with drill presses, CNC machining centers, and turret lathes configured for screw machine length tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and ensure the workpiece is firmly clamped before beginning operation.
