Built to Series 135 specifications, it features a 145-degree drill point angle, a web-thinned tapered web for easier penetration, and an AlTiN coating that extends tool life at elevated cutting temperatures. The bit measures 0.2090 inches in diameter (No. 4 wire size) with a 2-5\/8 inch overall length and a 1-inch flute length. Right-hand cut with a regular spiral flute and straight cylindrical shank, this bit suits CNC machining centers, drill presses, and manual operations requiring tight tolerances.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for machining alloy steels and titanium, where solid carbide construction and AlTiN coating provide the heat resistance and edge retention needed to hold tolerances. The screw machine length format — shorter than jobber length — offers greater rigidity and reduced deflection, making it the preferred choice in production environments and for drilling into hard or abrasive workpiece materials. Machinists, tool and die makers, and precision machine shop technicians are the primary users of this bit. It performs well in both through-hole and blind-hole applications within its maximum drilling depth of 0.8281 inches.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in alloy steel and titanium\u003c\/li\u003e\n  \u003cli\u003e145-degree split point with web thinning reduces thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (2-5\/8 inch OAL) provides enhanced rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.0002 to plus 0.0006 inches supports close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance replacement drill bit for production machining of alloy steels and titanium; fits any standard drill chuck or collet holder accepting a straight cylindrical shank at 0.2090 inches diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists familiar with proper speeds, feeds, and workholding practices for solid carbide tooling. Secure the shank fully in a collet or chuck before operation and verify runout is within acceptable limits before drilling. Coolant-through is not supported on this bit; use external flood coolant or cutting fluid appropriate to the workpiece material when drilling alloy steel or titanium. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and susceptible to damage from improper handling or interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2090 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.625 inches (2-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches (1-7\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.8281 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.0002 to plus 0.0006 inches\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 135\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 51780\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51732853227826,"sku":"51780","price":194.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f76b44f7e34536204d68c01d9f26669_c9c10b92-2afd-437f-9f53-6338adef6ddc.jpg?v=1788747551","url":"https:\/\/voomisupply.com\/products\/sgs-51780-solid-carbide-screw-machine-drill-bit-0-2090-in","provider":"Voomi Supply","version":"1.0","type":"link"}
