The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry force and improve chip evacuation at the start of the cut. A bright coating keeps the surface unaltered from the grinding process, preserving tight diameter tolerances of -0.0005 to 0.0000 inches. With a 3.5-inch overall length and a 2.125-inch spiral flute, this bit delivers the reach and chip clearance expected in production drilling. It is rated Material Grade C2 and classified as a high-performance drill bit.\u003c\/p\u003e\u003cp\u003eThis bit is suited for precision hole-making in steel, cast iron, aluminum, and similar materials where carbide hardness and rigidity outperform high-speed steel. The straight cylindrical shank seats directly in standard drill chucks and collet holders without adapters. Typical applications include maintenance and repair drilling, light production runs, and any situation where dimensional accuracy in the 0.2500- to 0.3000-inch size range is critical. Right-hand cut, regular spiral type, and a two-flute configuration make it compatible with conventional CNC machining centers, drill presses, and handheld power tools with adequate RPM control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eLetter I diameter (0.2720 inches) with tolerance held to -0.0005 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced thrust and cleaner entry\u003c\/li\u003e\n\u003cli\u003eBright finish preserves as-ground surface hardness with no coating-induced dimensional change\u003c\/li\u003e\n\u003cli\u003e2.125-inch flute length supports deep-hole chip clearance in jobber-length drilling\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks and collet holders without adapters\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 standard drill chucks and collet systems accepting a 0.2720-inch straight cylindrical shank across CNC machining centers, drill presses, and compatible handheld power tools.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of carbide drill bits should be performed by machinists or qualified technicians familiar with speeds, feeds, and rigidity requirements for carbide tooling. Secure the shank fully in a drill chuck or collet before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Power down and de-energize the machine spindle completely before changing bits. Do not use carbide bits in applications with excessive vibration or interrupted cuts without confirming the material grade is appropriate for that condition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: Letter I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.2720 inches\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\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 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: 0.2720 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Finish\/Coating\u003c\/strong\u003e: Bright\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\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\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: 79892584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727564898610,"sku":"79892584","price":95.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb5200c892f7a5d1ac995c3662e4286f.jpg?v=1788679446","url":"https:\/\/voomisupply.com\/products\/hertel-79892584-jobber-drill-bit-letter-i-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
