Built from micrograin solid carbide with a bright, uncoated finish, it delivers the hardness and edge retention needed for drilling composite materials and other demanding substrates. The 118-degree faceted point with web thinning promotes accurate entry and reduces thrust at startup. With a 3\/4-inch overall length and a regular right-hand spiral flute, the 51077 is suited for precision work in tight-clearance applications where controlled chip evacuation matters.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for use in applications requiring very small-diameter, high-precision holes, particularly in composite materials. The 5xD flute-to-diameter ratio and two-flute regular spiral geometry make it appropriate for CNC drilling operations and manual precision work in aerospace, electronics, and industrial fabrication environments. Its straight cylindrical shank is compatible with standard collets and drill chucks accepting 0.0180-inch shank diameters. The Series 101 designation follows DIN 338 standards, placing it within a recognized category for jobber-length drill geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and edge retention in composite and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted drill point with web thinning for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for non-ferrous and composite workpiece materials\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flute with 5xD ratio for effective chip evacuation in small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength without sacrificing cutting performance\u003c\/li\u003e\n  \u003cli\u003eDIN 338 compliant, Series 101 geometry for consistent jobber-length performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length drill bit for use in standard collet systems and drill chucks accepting a 0.0180-inch straight cylindrical shank.

Carbide is brittle and will fracture under side-loading or if dropped  -  handle with care during setup. Ensure the spindle is fully stopped and de-energized before changing tooling. Do not exceed manufacturer-recommended feed and speed parameters for the workpiece material, as carbide bits at this diameter are highly susceptible to breakage from excessive feed rate.\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: 77\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.46 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4330 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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: Faceted\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 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright, Uncoated\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: Composite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 101\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\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\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: 51077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743993889074,"sku":"51077","price":45.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a807363e8af94dd2bba390316076210.jpg?v=1788852559","url":"https:\/\/voomisupply.com\/products\/sgs-51077-jobber-drill-bit-wire-77-0-0180-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
