It features a 150-degree point angle with web thinning for reduced thrust and a 3-flute spiral design that improves chip evacuation over standard 2-flute geometry. The proprietary Ti-NAMITE-A coating enhances wear resistance and surface hardness for extended tool life in demanding materials. With an overall length of 3.25 inches and a 2-inch flute length, it is sized for general-purpose jobber applications in production machining, maintenance, and fabrication environments. Machinists, tool-and-die technicians, and industrial maintenance professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for precision drilling in ferrous and non-ferrous metals, alloys, and similar materials where tight diameter tolerances are required. The straight cylindrical shank fits standard drill chucks and collets without modification. The 5xD flute-to-diameter ratio and tapered web configuration make it appropriate for through-hole and blind-hole operations in CNC machining centers, drill presses, and handheld power tools where rigidity is maintained. Maximum drilling depth is 1.609 inches under recommended conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for high hardness and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-A proprietary coating improves wear resistance and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e150-degree point angle with web thinning reduces cutting force and walking tendency\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral design accelerates chip removal compared to standard 2-flute bits\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches supports close-tolerance hole requirements\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber length drill bit for use in standard drill chucks and collets accepting a 0.2420-inch straight shank.

Secure workpieces firmly to prevent movement during cutting. Follow machine manufacturer guidelines for feed rate and spindle speed when drilling with solid carbide tooling, as carbide is more brittle than high-speed steel and sensitive to lateral loading. Inspect the cutting edges before each use and replace the bit if chipping or coating wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.15 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Ti-NAMITE-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2420 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.609 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 58058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732668186930,"sku":"58058","price":116.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0896e2d3a14b02f7afdd69157abdd29_5f8956eb-edf2-468b-8a07-c01e37066fc0.jpg?v=1788745535","url":"https:\/\/voomisupply.com\/products\/sgs-58058-solid-carbide-drill-bit-letter-c-0-2420-in","provider":"Voomi Supply","version":"1.0","type":"link"}
