Built to DIN 6539 standards, this Series 730 bit features a 0.248-inch (letter size E) diameter, a 118-degree faceted point angle, and a web-thinned tip that reduces entry force and improves hole start accuracy. The micrograin carbide construction provides the hardness and wear resistance required for consistent performance in aluminum and other non-ferrous materials. It is suited for use in CNC machining centers, drill presses, and automatic screw machines where tight tolerances and repeatable results are required.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for general purpose drilling with a primary workpiece material designation of aluminum. The stub length format keeps the tool rigid and minimizes deflection in short-reach applications. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 0.848 inches (21.55 mm), it is well matched to production drilling, fixture work, and close-tolerance hole operations in light metal components. The straight-cylindrical shank seats directly into standard drill chucks and collet holders without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for reduced thrust and accurate hole starts\u003c\/li\u003e\n  \u003cli\u003eStub length design improves rigidity and limits deflection in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for aluminum and non-ferrous applications where coating is not required\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 6539 specification with h8 diameter tolerance for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general purpose stub-length carbide drill bit per DIN 6539, compatible with standard drill chucks and collet holders accepting a 6.30 mm straight-cylindrical shank.

Secure the shank fully in a properly sized collet or drill chuck before operation and verify runout is within acceptable limits for the application. Carbide tooling is brittle — avoid side loading, interrupted cuts without appropriate feed adjustments, or dropping the bit. Follow machine manufacturer guidelines for spindle speed and feed rate when drilling aluminum or non-ferrous stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.248 inches (Letter Size E)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 31.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.848 inches (21.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.30 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eSeries\u003c\/strong\u003e: 730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\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: 0.025 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: 9007300063000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728511041842,"sku":"9007300063000","price":62.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1921a5ddc478e7ad7240d9f7bd1ef7a_efdf080e-5ce0-4f95-8e26-fb7cc14cd3f0.jpg?v=1788692435","url":"https:\/\/voomisupply.com\/products\/guhring-9007300063000-carbide-stub-drill-bit-0-248-in","provider":"Voomi Supply","version":"1.0","type":"link"}
