It measures 27\/64 inch (0.4219 inch) in diameter with a 4.5-inch overall length and a 2.875-inch flute length. The 118-degree standard point angle and web-thinned, tapered web design reduce entry force and improve chip evacuation at the start of the cut. The bright (uncoated) finish is suited for applications where coating interaction with the workpiece material is a concern. This bit is sized and built for use by machinists, tool-and-die workers, and maintenance technicians working in shop or field environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is appropriate for drilling ferrous and non-ferrous metals, cast materials, and other hard substrates where carbide tooling outperforms high-speed steel. The straight-cylindrical shank accepts standard drill chucks and collet holders without modification. Its regular spiral flute geometry supports efficient chip removal in through-hole and blind-hole drilling operations across production and repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction rated at material grade C2 for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating for broad material compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with 2-flute regular spiral geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inch for close-tolerance hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement or production drill bit for use in any standard drill press, machining center, or hand drill equipped with a compatible chuck or collet accepting a 27\/64-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in the chuck or collet before operation and verify runout before beginning a cut. Power down and de-energize the spindle before changing or inspecting the bit. Solid carbide tooling is brittle compared to high-speed steel and should not be subjected to lateral shock loads or used in hand-drilling applications where flexing or angular entry is likely.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.875 inches (2-7\/8 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 27\/64 inch\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\u003eFinish\/Coating\u003c\/strong\u003e: Bright (Uncoated)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0005 to 0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 79892790\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737698107698,"sku":"79892790","price":187.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d41d7f5ac0d679b6b75cebbe8f255eac.jpg?v=1788792458","url":"https:\/\/voomisupply.com\/products\/hertel-79892790-carbide-jobber-drill-bit-27-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
