Measuring 0.1562 inches (5\/32 inch) in diameter with an overall length of 2-1\/16 inches and a 1-inch flute length, this bit is built for stub-length applications where rigidity and accuracy matter. The 135-degree split point reduces walking on entry and lowers thrust requirements. The M40CO-series cobalt construction provides heat and wear resistance beyond standard high-speed steel, making it suited for stainless steel, hardened alloys, and other difficult workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC drilling, and bench drilling applications where short-length rigidity is required. The straight-cylindrical shank fits standard drill chucks without modification. The regular spiral flute with a 2.5xD flute-to-diameter ratio promotes chip evacuation in short-bore drilling. It is used by machinists, maintenance technicians, and metalworking tradespeople working with hard ferrous and non-ferrous materials. The web-thinned, tapered web configuration further reduces cutting resistance at the point for cleaner entry into hard stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1562 inch (5\/32 inch) diameter with 135-degree split point for accurate, low-thrust entry\u003c\/li\u003e\n  \u003cli\u003eM40CO cobalt construction for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length design provides rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance at the drill point\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for heavy-duty drill bit performance\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 standard drill chucks and screw machine setups accepting a 0.1562 inch straight-cylindrical shank, falling within the M40CO series range of 0.1500 to 0.2000 inch diameter bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists or metalworking technicians in drill press, CNC, or hand-held drilling equipment. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Coolant-through is not supported on this bit; use appropriate cutting fluid applied externally when drilling hard or stainless materials to manage heat buildup. Follow applicable shop safety procedures and machine guarding requirements during use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1562 inches (5\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\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\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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: 5995987\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51692150423858,"sku":"5995987","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0fc5f6262074872d44705f45fbae1b7_b2e5dbbd-605f-475d-a239-6b7e492bb037.jpg?v=1788293789","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5995987-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
