Built to M41 cobalt high-speed steel standards, it carries a 135-degree split point that reduces walking and requires no center punch on most materials. The straight-cylindrical shank seats securely in standard drill chucks, and the web-thinned, tapered web construction lowers thrust requirements while maintaining rigidity. At 2-1\/16 inches overall length with a 1-inch flute, this stub-length geometry provides excellent rigidity and reduced deflection in short-reach drilling applications. Rated as a heavy-duty, high-performance tool, it meets ANSI specification requirements.\u003c\/p\u003e\u003cp\u003eThis bit is sized at 0.152 inches in diameter, corresponding to wire gauge size 24, placing it in the 0.1500 to 0.2000 inch drill bit size range. Screw machine length bits like this are commonly used in production machining, CNC operations, manual drill press work, and tight-clearance hand-drilling tasks where a standard jobber-length bit would flex or deflect. The right-hand spiral flute design evacuates chips efficiently when drilling steels, stainless alloys, cast iron, and other hard or work-hardening materials where cobalt tooling is the appropriate choice.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM41 cobalt construction handles hard and abrasive materials where standard HSS bits wear prematurely\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and minimizes drill walking without a center punch\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers axial cutting forces and improves chip clearance\u003c\/li\u003e\n\u003cli\u003eStub screw machine length (2-1\/16 inches overall, 1-inch flute) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 2.5xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a heavy-duty OEM-style replacement or production-use drill bit for applications requiring a wire gauge size 24 (0.152 inch) screw machine length cobalt drill bit in the PRECISION TWIST DRILL M41CO series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by machinists, tool-and-die tradespeople, or qualified maintenance technicians familiar with cutting tool selection and machine operation. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before beginning any drilling operation. Verify spindle speed is appropriate for the workpiece material and drill diameter before engaging the cut. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.152 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: 24\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 (M41 Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: M41CO\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\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\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\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5996185\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51722587537714,"sku":"5996185","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa2be07eba6984ccd5f161f94448d961_5d9ed3df-70b0-4a63-a722-20fcdf8a5f0a.jpg?v=1788593184","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5996185-cobalt-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
