Ground to a 3.5 mm (0.1378 inch) diameter with a 118-degree standard point angle, this bit delivers consistent entry geometry in ferrous and non-ferrous materials. The bright finish is applied without coating buildup, maintaining tight dimensional tolerances at the cutting edge. The two-flute spiral design with a tapered, web-thinned construction reduces thrust and improves chip evacuation. Machinists and maintenance technicians working with CNC equipment, drill presses, or portable units rely on solid carbide tooling like this for repeatable hole quality in harder workpiece materials.\u003c\/p\u003e\u003cp\u003eThis jobber drill bit suits general-purpose hole-making operations in machine shops, fabrication environments, and industrial maintenance settings. The straight cylindrical shank fits standard drill chucks across a wide range of machines. With a flute length of 1.25 inches and an overall length of 2.5 inches, it is sized for conventional jobber-depth applications where reach and rigidity are balanced. Material grade C2 carbide positions it for use in cast iron, aluminum alloys, plastics, and similar materials where high-speed steel tooling may not provide adequate tool life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life versus HSS in harder materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eBright finish maintains edge sharpness without coating interference\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral geometry promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of -0.0005 to 0.0000 inches ensures precise hole sizing\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for broad chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length carbide drill bit suited for standard drill chucks accepting a 0.1378-inch straight cylindrical shank.

Secure the shank fully in a properly sized drill chuck and verify runout before beginning a cut. Ensure the workpiece is firmly fixtured to prevent movement during drilling. Solid carbide is brittle compared to HSS  -  avoid lateral loading, interrupted cuts without proper setup, or dropping the tool on hard surfaces, as these can cause chipping or fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.5 mm (0.1378 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1378 inches\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\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\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 74459959\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51740652273970,"sku":"74459959","price":29.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec27e3b20d8194dfb86d80c0bc5db454.jpg?v=1788826484","url":"https:\/\/voomisupply.com\/products\/hertel-74459959-solid-carbide-jobber-drill-bit-3-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
