Built to the M42CO series specification, it features a 135-degree split point that reduces walking at startup and lowers the thrust needed to penetrate tough workpieces. The straight-cylindrical shank fits standard drill chucks without adapters. At 0.29 inches in diameter (Letter L), it falls in the heavy-duty grade category and is web-thinned for improved chip clearance and cutting efficiency. This bit is manufactured to ANSI standards and is suited for production and maintenance drilling environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in screw machine operations, short-hole drilling, and production drilling applications where a stub-length tool is preferred for rigidity. It is well suited for drilling hard metals, alloy steels, stainless steel, and other materials that wear down standard high-speed steel tooling. The right-hand spiral flute configuration and coated cobalt construction make it a practical choice for machine shop technicians, industrial maintenance mechanics, and tool room personnel working on tight-tolerance applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction rated for high-performance drilling in hard and abrasion-resistant materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces bit walking and cuts entry thrust requirements\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design improves chip evacuation through the 1-9\/16 inch flute length\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity compared to jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw chucks without additional adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes; ANSI specification compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct production tooling option for applications requiring a 0.29 inch (Letter L) straight-shank screw machine length drill bit in the M42CO cobalt series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed and operated by machining professionals and industrial maintenance technicians using drill presses, CNC machining centers, or hand-held power drills with compatible chuck sizes. Ensure the machine spindle and chuck are fully stopped before inserting or removing the bit. Confirm the shank is fully seated and the chuck is properly tightened before beginning any drilling operation. Always use appropriate cutting fluid or coolant for the workpiece material to extend tool life, and wear appropriate eye protection in compliance with applicable shop safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-9\/16 inches\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M42CO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.25 to 0.30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 5996503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51714027028786,"sku":"5996503","price":21.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/691739fe851d894f4ec47cb5cae18c43_ed7cd7d6-57ab-43a4-a02e-8f87d25fd1cc.jpg?v=1788495938","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996503-cobalt-drill-bit-0-29-in","provider":"Voomi Supply","version":"1.0","type":"link"}
