Built to DIN 338 standards, it features a 23\/64 inch (0.3594 inch) diameter, a 118-degree facet point, and a web-thinned, tapered web construction that reduces thrust and improves chip evacuation at entry. The micrograin carbide substrate delivers edge retention and rigidity beyond what high-speed steel can provide in the same diameter range. A bright, uncoated finish means the bit is ready to run as delivered. This is a two-flute, right-hand cutting tool intended for production and maintenance machinists who need repeatable hole quality in harder materials.\u003c\/p\u003e\u003cp\u003eThe SGS 51123 is suited for drilling steel, cast iron, aluminum, and non-ferrous metals in vertical mills, drill presses, and CNC machining centers. With a 2-3\/4 inch flute length and a 4-1\/4 inch overall length, it fits standard tool holders and drill chucks sized for a 0.3594 inch straight cylindrical shank. The 5xD flute-to-diameter ratio and maximum drilling depth of 2.2 inches make it appropriate for through-hole and blind-hole operations in typical workpiece thicknesses encountered in job-shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior hardness and edge retention compared to HSS alternatives\u003c\/li\u003e\n\u003cli\u003e118-degree facet point with web thinning reduces entry thrust and centers the bit accurately on the workpiece\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation in steel, cast iron, and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to affect diameter tolerance; diameter tolerance held to -0.0005 to 0.0000 inch\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 standard for jobber-length drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet systems accepting a 0.3594 inch straight shank.

Ensure the spindle and workpiece are fully secured before engaging the drill. Verify chuck or collet runout is within acceptable limits before use, as excess runout accelerates carbide wear and increases breakage risk. Carbide drills are brittle compared to HSS — avoid side loading and interrupted cuts without confirming the grade is rated for that application.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 23\/64 inch (0.3594 inch \/ 9.13 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/4 inches (4.2500 inches \/ 107.95 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches \/ 69.85 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3594 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Facet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inch (-0.0127 to 0.0000 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Aluminum, Non-Ferrous\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: 101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 51123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732735492402,"sku":"51123","price":128.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/06f86860b717ee5afa1f1f27816988c5_443477b1-85a1-4534-aea8-ecb88faa2d68.jpg?v=1788746152","url":"https:\/\/voomisupply.com\/products\/sgs-51123-solid-carbide-jobber-drill-bit-23-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
