Built from C2-grade solid carbide with a bright finish, this bit is suited for precision drilling in hard materials where dimensional accuracy and cutting edge life are critical. The 118-degree standard point angle provides a reliable entry geometry across a wide range of work materials. At 1.125 inches overall length with a 0.375-inch spiral flute, this is a compact, high-performance tool for small-diameter drilling applications. A web-thinned, tapered web configuration reduces thrust and improves chip clearance at the cutting face.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for use in machining, fabrication, and maintenance applications that require tight-tolerance, small-diameter holes. Wire gauge No. 68 sizing is common in instrument manufacturing, electronics assembly, precision mechanical work, and similar trades where undersized or close-tolerance clearance holes are required. The straight-cylindrical shank accepts standard drill chucks on benchtop drill presses, CNC machining centers, and handheld precision drilling tools. Right-hand cut with a regular spiral flute makes it compatible with standard right-hand rotation spindles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\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. 68 wire size, 0.0310-inch diameter, with diameter tolerance of -0.0005 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e118-degree standard drill point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eBright finish coating, 2-flute regular spiral design, right-hand cutting direction\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.0310 inches for use in standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eCoolant-through: No — suited for dry or externally lubricated drilling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a jobber-length replacement or production drill bit for applications requiring wire gauge No. 68 sizing in solid carbide.

Secure the shank fully in a precision drill chuck before operation and verify spindle runout is within acceptable limits, as carbide bits at this diameter are sensitive to deflection and side loading. Do not use in applications that exceed the bit diameter tolerance range or apply lateral force during drilling. Handle with care — solid carbide is brittle and will fracture if dropped onto hard surfaces.\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. 68\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0310 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\u003eOverall Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.375 inches\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Material\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\u003eFinish\/Coating\u003c\/strong\u003e: Bright\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 79891669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733044887858,"sku":"79891669","price":22.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c44e73a9b41300de5cf81a58e4fe0127.jpg?v=1788750913","url":"https:\/\/voomisupply.com\/products\/hertel-79891669-solid-carbide-jobber-drill-bit-no-68","provider":"Voomi Supply","version":"1.0","type":"link"}
