Built from solid carbide and coated with SGS Ti-NAMITE-A AlTiN finish, it delivers extended tool life and heat resistance in applications where high-speed steel bits fall short. The 145-degree notched point reduces thrust and improves self-centering at entry. Overall length is 4-1\/16 inches with a 2-3\/16-inch flute length. The straight shank measures 0.5000 inches in diameter, fitting standard drill chucks and tool holders. This bit is suited for CNC machining centers, drill presses, and manual operations where precise, stub-length drilling is required.\u003c\/p\u003e\u003cp\u003eThe SGS 51359 is intended for machining alloy steels and titanium in industrial and production environments. Its screw machine length profile — shorter than jobber-length bits — reduces deflection and improves rigidity in tight setups or shallow-hole applications. The 3xD flute-to-diameter ratio and regular spiral flute geometry support consistent chip evacuation in ferrous and exotic metals. Machinists, tool-and-die professionals, and maintenance mechanics working on CNC or manual equipment will find this bit appropriate for precision, repeatable hole production.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-A AlTiN coating provides thermal barrier and extended tool life in titanium and alloy steel\u003c\/li\u003e\n\u003cli\u003e145-degree notched point reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers cutting resistance and heat buildup at the tip\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length body minimizes deflection in short-reach drilling setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling alloy steels and titanium; compatible with standard straight-shank drill chucks and collet-style tool holders accepting a 0.5000-inch shank diameter.

Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify chuck or collet runout is within acceptable limits before use, as solid carbide bits are sensitive to eccentric loading. Coolant-through is not available on this bit; use external flood or mist coolant appropriate for the workpiece material when applicable.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-3\/16 inches (2.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-49\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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: Alloy Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0003 to +0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 135\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: 51359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731126583602,"sku":"51359","price":478.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/201a62260b4b4b27d1df2f9d82ff8041.jpg?v=1788727270","url":"https:\/\/voomisupply.com\/products\/sgs-51359-7-16-inch-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
