Built to Series M41CO standards, this bit features a 135-degree split point that reduces walking and cutting force on entry, making it well-suited for production drilling environments where precision and tool life matter. The straight-cylindrical shank is compatible with standard drill chucks, and the right-hand spiral flute geometry promotes efficient chip evacuation. At 0.1285 inches (Wire Size 30) in diameter, this bit handles applications where tight tolerances are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in metalworking and machining applications involving hard materials such as stainless steel, high-strength alloys, and other difficult-to-machine stock. The screw machine length designation means a shorter overall length compared to jobber-length bits, which provides greater rigidity and reduces deflection in close-quarters or fixture-based drilling setups. Machinists, tool-and-die technicians, and maintenance mechanics working with drill presses, CNC machines, or hand drills will find this bit appropriate for precision hole work in production and repair contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt (M41 grade) construction for heat and wear resistance in hard material drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust force and eliminates the need for center-punching\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web design extends tool life and improves cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (1-15\/16 inches overall) provides added rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 2.5xD flute-to-diameter ratio for effective chip removal\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard drill bit for use in any drill press, hand drill, or CNC setup accepting a straight-cylindrical shank at Wire Size 30 (0.1285 inches) diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachinists and maintenance technicians should ensure the drill chuck is clean and properly tightened before operation to prevent shank slippage. Power down the machine and follow lockout\/tagout procedures before changing bits. Use appropriate cutting fluid or coolant when drilling hard alloys to preserve bit life, as this bit does not feature through-coolant capability. Inspect the split point for chipping or wear before each use, as cobalt bits used beyond their service life can fracture under load.\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: 0.1285 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 30\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 (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\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\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\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\u003eSeries\u003c\/strong\u003e: M41CO\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: 5996041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51694530953522,"sku":"5996041","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_86196d6c-87af-4dca-b779-31cb9bbb272c.jpg?v=1788325126","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996041-cobalt-drill-bit-0-1285-in","provider":"Voomi Supply","version":"1.0","type":"link"}
