Built from C2-grade solid carbide with a bright finish, it features a standard 118-degree split point and a web-thinned, tapered web for improved centering and reduced thrust on entry. The spiral flute geometry is a regular right-hand configuration with two flutes. Overall length is 1.5 inches, with a flute length of 0.75 inches. The straight-cylindrical shank matches the 0.0670-inch drill diameter. This bit is rated as a high-performance grade tool suited to precision drilling applications in tight-tolerance work.\u003c\/p\u003e\u003cp\u003eWire gauge drill bits in the No. 51 range are commonly used in metalworking, electronics fabrication, toolmaking, and light manufacturing where precise small-diameter holes are required. The solid carbide construction makes this bit appropriate for drilling hardened steels, cast iron, nonferrous alloys, and composites where high-speed steel tooling wears too quickly. It is typically run in CNC machining centers, drill presses, or high-speed hand-held spindles. The diameter tolerance of -0.0005 to 0.0000 inches ensures hole consistency within close-tolerance specifications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, C2 material grade, for extended tool life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eNo. 51 wire size, 0.0670-inch decimal diameter with tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for accurate starting and reduced thrust\u003c\/li\u003e\n\u003cli\u003eRegular spiral, two-flute right-hand cutting geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright finish, no coating, suitable for general-purpose and non-ferrous applications\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch overall length with 0.75-inch flute length for short-reach precision work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length solid carbide drill bit for use in standard straight-shank drill chucks and collets accepting a 0.0670-inch shank diameter across CNC machining centers, drill presses, and precision spindle equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by machinists or trained metalworking professionals familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank firmly in a compatible precision drill chuck or collet before operation; carbide bits are brittle and will fracture under side load or improper runout. Ensure the spindle and workpiece are properly fixtured to minimize vibration, which is a primary cause of small-diameter carbide breakage. Coolant-through capability is not available on this bit, so apply cutting fluid externally when drilling ferrous materials to manage heat.\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. 51\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0670 inches\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright (uncoated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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: 0.0670 inches\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: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 79891834\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747099640114,"sku":"79891834","price":32.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b0a43aa83e35a8841a0e186cbdbd0a4.jpg?v=1788876037","url":"https:\/\/voomisupply.com\/products\/hertel-79891834-solid-carbide-jobber-drill-bit-no-51","provider":"Voomi Supply","version":"1.0","type":"link"}
