Built to Series M40CO standards, it features a 135-degree split point for fast, accurate starts with minimal walking, and a web-thinned, tapered web configuration that reduces thrust during entry. The straight-cylindrical shank seats securely in standard drill chucks. At 0.1875 inches in diameter with an overall length of 2.1875 inches and a flute length of 1.125 inches, this is a compact, stub-length bit suited for work in tight clearances. ANSI-compliant construction holds dimensional tolerances trade professionals depend on.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for right-hand cutting in hard materials where standard high-speed steel bits fall short. The screw machine length profile makes it a reliable choice for machine shop work, production drilling, and field service applications where rigidity and reduced deflection matter. It fits standard drill presses, CNC machines, and hand drills with compatible chuck capacity. The 2.5xD flute-to-diameter ratio balances chip evacuation with bit stiffness across a range of materials classified as hard or high-hardness workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt M40 grade construction for drilling hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and eliminates center-punching in many applications\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web lowers cutting resistance and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eScrew machine length profile provides maximum rigidity and minimal deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute design for standard drill press and hand drill use\u003c\/li\u003e\n  \u003cli\u003eANSI-compliant Series M40CO for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for applications requiring a 0.1875-inch diameter screw machine length drill bit within the 0.1500 to 0.2000 inch size range, compatible with any chuck accepting a straight-cylindrical shank of this diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this bit is typically performed by machinists, maintenance technicians, or experienced trade professionals operating drill presses, CNC equipment, or hand drills. Ensure the chuck is fully tightened and the workpiece is securely fixtured before drilling. Use appropriate cutting fluid for hard materials to extend tool life and maintain hole quality. Inspect the bit for wear or damage before each use and replace when cutting performance degrades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 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 M40 Grade\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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: M40CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: 5995954\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51704642666802,"sku":"5995954","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_a38f5d75-91f6-444d-8450-df3bcb0dddcb.jpg?v=1788424015","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995954-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
