Designed for right-hand cutting with a regular spiral flute, it delivers consistent chip evacuation in general-purpose drilling applications. The straight-cylindrical shank seats securely in standard drill chucks and collets. At an overall length of 74.00 mm (approximately 2.91 inches) and a flute length of 34.00 mm (approximately 1.34 inches), this stub-length geometry provides added rigidity compared to jobber-length bits, reducing deflection in short-hole and production drilling work. It carries a DIN 6539 specification and an h8 diameter tolerance.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use on aluminum and other non-ferrous or soft ferrous materials in general-purpose machining environments. The stub-length design is well suited to screw machine, CNC, and drill press applications where reduced overhang improves positional accuracy. The 3xD flute-to-diameter ratio and web-thinned point geometry lower entry thrust, making the bit practical for close-tolerance production runs. Machinists, tool-and-die shops, and precision fabrication operations are the primary users of Series 730 tooling.\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 general-purpose applications\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eStub-length body (overall 74.00 mm) provides rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with 6.90 mm shank diameter fits standard chucks and collets\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; no coolant-through feature keeps setup simple\u003c\/li\u003e\n  \u003cli\u003eDIN 6539 specification with h8 diameter tolerance for close-tolerance fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose stub-length drill bit conforming to DIN 6539, compatible with standard straight-shank drill chucks and collets accepting a 6.90 mm shank.

Primary workpiece material is aluminum; general-purpose grade supports a range of soft to medium-hardness materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed with the machine fully powered down and the spindle at a complete stop. Secure the straight-cylindrical shank fully within the chuck or collet to the recommended grip depth before tightening. Inspect the cutting edges and point geometry for chips or wear before each use, as carbide tooling can fracture if run while damaged. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2717 inches (Letter I)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Micrograin Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (approximately 2.91 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (approximately 1.34 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.90 mm (approximately 0.272 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9310 inches (23.65 mm)\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: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 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: 9007300069000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727252128050,"sku":"9007300069000","price":69.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1921a5ddc478e7ad7240d9f7bd1ef7a.jpg?v=1788675450","url":"https:\/\/voomisupply.com\/products\/guhring-9007300069000-carbide-stub-drill-bit-0-2717-in","provider":"Voomi Supply","version":"1.0","type":"link"}
