It measures 0.1406 inches (9\/64 inches) in diameter with an overall length of 1-15\/16 inches and a flute length of 15\/16 inches. The 135-degree split point reduces walking on entry and lowers thrust requirements, making it well suited for production drilling and tight-tolerance work. The right-hand spiral flute with web-thinned, tapered web geometry promotes efficient chip evacuation. At 0.04167 pounds, this is a compact, single-piece bit built to ANSI standards for consistent dimensional accuracy.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for use in screw machine operations, CNC drill presses, hand-held power drills, and bench drill press applications where a short, rigid cutting length is required to minimize deflection. The M40CO series cobalt grade is a common choice for machinists, maintenance technicians, and fabricators working with stainless steel, hardened alloys, cast iron, and other hard materials that generate significant heat at the cutting edge. The 2.5xD flute-to-diameter ratio keeps the tool stiff in short-reach applications typical of screw machine and production-line drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt M40CO grade construction for heat resistance in hard-material drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web geometry improves chip flow and reduces torque\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flute for standard drilling operations\u003c\/li\u003e\n  \u003cli\u003eBuilt to ANSI specification 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 compatible with standard straight-shank drill chucks accepting a 0.1406-inch diameter bit in screw machine length format.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a drill press, CNC machine, or hand-held power drill equipped with a compatible straight-shank chuck. Secure the shank firmly in the chuck before operation and verify chuck runout is within acceptable tolerance to protect the small-diameter bit from breakage. Always reduce feed rate when breaking through the back side of the workpiece. Use appropriate cutting fluid or coolant for hard-material applications to extend tool life, noting that this bit does not support internal coolant-through delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M40CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04167 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PRECISION TWIST DRILL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5996019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51691737809202,"sku":"5996019","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7.jpg?v=1788289071","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996019-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
