Ground to a 135-degree split point with web thinning, it starts on center without a pilot hole and reduces thrust in tough stock. The straight-cylindrical shank seats securely in standard drill chucks. At 0.18 inches in diameter (Wire Size 15) with a 1-1\/8 inch flute length and 2-3\/16 inch overall length, this stub-length bit delivers maximum rigidity and minimal deflection. It belongs to the M41CO series, built to ANSI standards for consistent geometry and interchangeability across production setups.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for metalworking applications involving hard ferrous and non-ferrous materials where standard high-speed steel bits fall short. The screw machine length format is a standard choice in machine shop environments, CNC setups, drill press operations, and production-line work where short flute length reduces chatter and improves hole accuracy. Machinists, tool-and-die technicians, and maintenance professionals working with stainless steel, hardened alloys, titanium, and similar hard materials will find this bit appropriate for their drilling requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction handles hard and heat-resistant workpiece materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides maximum rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 2.5xD flute-to-diameter ratio promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard three-jaw drill chucks\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration and ANSI-standard geometry for consistent, repeatable results\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use screw machine drill bit compatible with any standard drill press, CNC machining center, or hand drill accepting a straight-cylindrical shank in the 0.18-inch diameter class.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using standard drill chuck tooling. Secure the shank fully in the chuck and verify runout before beginning a cut. Appropriate cutting fluid or coolant is recommended when drilling hard ferrous or alloy materials to extend tool life, even though this bit does not support through-coolant delivery. Always wear appropriate eye protection and follow shop safety procedures when operating rotating cutting tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 15\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-1\/8 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\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\u003eTool Material\u003c\/strong\u003e: Cobalt (M41 Grade)\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eSeries\u003c\/strong\u003e: M41CO\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: 0.04 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: 5996046\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714847998258,"sku":"5996046","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_a5b19ccb-054d-4893-a0f1-bc0d11512e5d.jpg?v=1788506999","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996046-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
