It carries a 7.80 mm (0.3071 inch) diameter, a standard 118-degree split point, and an overall length of 117.00 mm (4.61 inches), with a 75.00 mm (2.95-inch) flute length. The web-thinned, tapered web geometry reduces thrust at entry and helps center the bit without a pilot hole. Right-hand spiral flutes evacuate chips efficiently. This bit is manufactured to DIN 338 tolerances, making it a reliable choice for precision drilling in metal fabrication, mechanical assembly, and general machine-shop work.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is suited for drilling steel, cast iron, aluminum, and similar materials in both production and maintenance environments. The straight-cylindrical shank fits standard three-jaw drill chucks found on drill presses, hand drills, and CNC machining centers. Its 5xD flute-to-diameter ratio provides the reach needed for through-hole work in typical workpiece thicknesses encountered in sheet metal, structural steel, and light plate applications. Machinists, pipefitters, ironworkers, and maintenance technicians routinely use DIN 338 jobber drills for everyday hole-making tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7.80 mm diameter ground to DIN 338 tolerance of +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction for wear resistance in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide coating reduces friction and provides mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers drilling thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle suits general-purpose metal drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with regular helix for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill for use in any standard drill chuck accepting a 7.80 mm straight-cylindrical shank, including drill presses, hand drills, and CNC spindles.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in a properly sized drill chuck before operation. Always wear appropriate eye protection and secure the workpiece in a vise or fixture — never hand-hold stock during drilling. Use cutting fluid or coolant when drilling steel to extend tool life and maintain hole-size accuracy. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.80 mm (0.3071 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 117.00 mm (4.61 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 75.00 mm (2.95 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.80 mm (0.3071 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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: 0.068 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9002050078000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729092313394,"sku":"9002050078000","price":17.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_5cc709bc-5081-49c6-8f6f-8dd042ea2a9c.jpg?v=1788699821","url":"https:\/\/voomisupply.com\/products\/guhring-9002050078000-jobber-drill-7-80mm-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
