It features a 118-degree faceted drill point and a two-flute right-hand spiral cut geometry. The bit is manufactured from micrograin solid carbide and carries a bright, uncoated finish. The shank is straight-cylindrical with a shank diameter matching the drill diameter at 0.0145 inches. Overall length is 0.75 inches with a flute length of 0.1875 inches. Installed by machinists, tooling technicians, and precision fabricators, this bit is built for small-diameter drilling applications requiring tight tolerances and consistent geometry.\u003c\/p\u003e\u003cp\u003eThe SGS 51079 is suited for drilling composite workpiece materials where small-diameter precision holes are required. The web-thinned, tapered web construction reduces thrust load during entry, improving cut initiation in hard or layered composite substrates. The 5xD flute-to-diameter ratio supports chip evacuation in deep-relative-to-diameter passes. This bit fits production, maintenance, and prototype applications where wire-gauge drill sizes are specified by design drawings or engineering callouts. It conforms to DIN 338 standards and is part of the SGS Series 101 jobber length line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life in composite materials\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point for clean entry and reduced walking on flat surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces axial thrust during drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand, two-flute spiral geometry supports chip clearing in small-diameter bores\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard collets and drill chucks rated for the diameter\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application drill bit for use in standard collet chucks, precision drill chucks, or CNC toolholders accepting a 0.0145-inch straight shank.

Ensure the spindle and toolholder are fully stopped and de-energized before bit changes. At this diameter, excessive feed pressure will snap the bit; use a low-feed, high-RPM strategy consistent with carbide tooling recommendations for composite materials. Handle carbide bits carefully to avoid chipping the flutes or point during storage and setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 79\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0145 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 0.37 mm\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\u003eMaterial\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0145 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.433 inches\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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Composite\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\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: 51079\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51743833522482,"sku":"51079","price":46.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/07a3557bd8bd2772781289e54573947e.jpg?v=1788850177","url":"https:\/\/voomisupply.com\/products\/sgs-51079-solid-carbide-jobber-drill-bit-no-79","provider":"Voomi Supply","version":"1.0","type":"link"}
