Built to DIN 6539 standards, this stub-length bit features a 118-degree faceted point angle and a web-thinned tip that reduces entry force and improves chip flow. The straight-cylindrical shank measures 7.14 mm in diameter and fits standard drill chucks without modification. At 74 mm overall length and a 34 mm flute length, the short stub profile maximizes rigidity and minimizes deflection in CNC lathes, screw machines, and machining centers. It carries an h8 diameter tolerance for consistent, repeatable hole sizing.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling operations where short cycle times and hole accuracy are priorities. The Series 730 geometry with a 3xD flute-to-diameter ratio and regular spiral flute pattern is well-matched to aluminum, light alloys, and similar non-ferrous materials in both manual and automated setups. The bright uncoated finish allows direct inspection of the cutting edges and is appropriate for applications where coating buildup or chemical reaction with the workpiece material is a concern. Right-hand cut direction is standard for conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003eDIN 6539 standard, h8 diameter tolerance for repeatable hole sizing\u003c\/li\u003e\n\u003cli\u003eStub length profile minimizes deflection in short-reach drilling applications\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute regular spiral for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose stub drill bit for use in screw machines, CNC lathes, and machining centers accepting a straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before changing or inspecting the bit. Secure the straight-cylindrical shank fully within the chuck jaws to the recommended grip depth before operation. Do not exceed the maximum drilling depth of 0.917 inches as specified for this stub-length geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2812 inches (9\/32 inch, Size K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.917 inches (23.29 mm)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.033 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9007300071400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51740146532658,"sku":"9007300071400","price":80.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1921a5ddc478e7ad7240d9f7bd1ef7a_c15ae15e-f02b-4c0c-8503-c2010ccb46e4.jpg?v=1788822885","url":"https:\/\/voomisupply.com\/products\/guhring-9007300071400-solid-carbide-stub-drill-bit-9-32","provider":"Voomi Supply","version":"1.0","type":"link"}
