With a 0.266 inch (Letter H) diameter, a 140-degree notched point, and a web-thinned tip geometry, it delivers clean entry and reduced thrust when working through tough stock. The C2 carbide grade provides the hardness needed for demanding production and maintenance applications. At 2.6875 inches overall length with a 1.5 inch flute length, it is suited for short-hole and controlled-depth work where rigidity matters. This bit is sold individually and is appropriate for use by machinists, maintenance mechanics, and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for right-hand cutting in ferrous and high-strength materials including stainless steel, steel, chrome alloy, heat-treated alloy, nickel alloy, and titanium alloy. It fits standard drill chucks and is appropriate for CNC machining centers, drill presses, and manual operations where straight-flute geometry is preferred over spiral fluting — particularly in thin-wall or through-hole applications where chip ejection is managed by the operator or coolant system. Coolant-through capability is not supported on this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight-flute geometry preferred for thin-wall and brittle-material drilling where spiral flutes may cause chatter\u003c\/li\u003e\n  \u003cli\u003eC2 carbide grade provides high wear resistance in hard ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree notched point reduces thrust and centers the bit without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned design lowers cutting force and extends tool life in production runs\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains dimensional accuracy and allows visual inspection of cutting edges\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.0000 to -0.0005 inches ensures close-fit hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a straight-flute carbide drill bit for use in standard drill chucks and collet systems accepting a 0.266 inch shank diameter.

Secure the bit fully in a properly sized chuck or collet before operation and verify runout before beginning a cut. Do not exceed the recommended maximum drilling depth of 2.688 inches for this tool length. Carbide tooling is brittle — avoid interrupted cuts or side loading that can cause chipping or fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.266 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\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: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 470\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\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: 16691396\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754053599538,"sku":"16691396","price":127.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/de25638c235c729b020cafaf676046f6.jpg?v=1788943187","url":"https:\/\/voomisupply.com\/products\/hertel-16691396-straight-flute-carbide-drill-bit-0-266-in","provider":"Voomi Supply","version":"1.0","type":"link"}
