Built to the M41CO series specification, this bit features a 135-degree split point with web thinning for fast penetration and reduced walking on entry. The straight-cylindrical shank fits standard drill chucks without modification. At 1-15\/16 inches overall length with a 15\/16-inch flute, this stub-length geometry provides added rigidity compared to jobber-length bits, making it well suited for high-cycle production and precision work in confined spaces. Machinists, tool and die technicians, and maintenance professionals install this bit in handheld and bench-mounted drilling equipment.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized to Wire Gauge 28, with a decimal diameter of 0.1405 inches. The screw machine length format is commonly used in CNC drilling, drill press operations, and automated machining fixtures where shorter overhang reduces deflection and improves hole accuracy in tough materials. The cobalt construction allows operation at higher cutting speeds and temperatures than standard high-speed steel bits, making it a practical choice for stainless steel, hardened alloys, cast iron, and other hard workpiece materials where conventional HSS bits wear prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt M41 material grade for high heat resistance and extended tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and self-centers on entry without a center punch\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction improves chip clearance and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eScrew machine stub length adds rigidity and reduces deflection in tight drilling applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut spiral flute evacuates chips efficiently during through-hole drilling\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliance ensures dimensional interchangeability with other ANSI-rated tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a heavy-duty screw machine length drill bit for use in standard drill chucks accepting straight-cylindrical shanks.

Always power down and lock out the drilling equipment before installing or removing the bit. Use appropriate cutting fluid or coolant when drilling hard materials to extend tool life, noting this bit does not support internal coolant-through delivery. Follow applicable shop safety and ANSI B11 machine tool standards for drilling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M41 Grade)\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 Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned, Tapered Web\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 2.5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eTool Performance\u003c\/strong\u003e: High Performance, Heavy Duty\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: 5996027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51720032878898,"sku":"5996027","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_41408a14-b819-4b6f-a257-b6f55ea5b8a2.jpg?v=1788560331","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996027-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
