It features a 5.30 mm diameter, a 118-degree faceted point angle, and a bright\/uncoated finish. The micrograin carbide construction delivers hardness and edge retention well suited to short-cycle, high-repetition drilling. The web-thinned point reduces entry force and helps center the bit at the start of the cut. This bit is typically installed and operated by machinists, toolroom technicians, and CNC operators working on production or maintenance machining tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for general-purpose drilling in aluminum as its primary workpiece material, though the solid carbide construction also handles a range of non-ferrous and ferrous materials in appropriate conditions. The stub length format provides added rigidity over jobber-length bits, making it a preferred choice in drill presses, CNC machining centers, and screw machines where minimizing deflection is critical. The straight-cylindrical shank allows direct chuck or collet mounting in standard toolholding systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5.30 mm diameter with h8 tolerance for precise, consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point angle with web thinning for reduced entry force and improved self-centering\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eStub length format (62 mm OAL) provides increased rigidity and reduced deflection vs. jobber-length bits\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a range of cutting fluids and dry-cutting setups\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with 2-flute configuration for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6539 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose stub-length drill bit per DIN 6539, compatible with standard straight-bore chucks and collets accepting a 5.30 mm straight-cylindrical shank in drill presses, CNC machining centers, and screw machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by qualified machinists or toolroom technicians familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and power is isolated before mounting or removing the bit from the chuck or collet. Secure the straight-cylindrical shank fully within the holder to the manufacturer-recommended engagement depth to prevent pullout under load. Do not exceed the recommended maximum drilling depth of 18.05 mm for this stub-length configuration without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.30 mm (0.2087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62 mm (2.4409 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 26 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.30 mm (0.2087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 18.05 mm (0.711 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\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eWeight\u003c\/strong\u003e: 0.016 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: 9007300053000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747473031474,"sku":"9007300053000","price":56.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1921a5ddc478e7ad7240d9f7bd1ef7a_e766a7d0-92ea-4075-8edf-3c8be54f5951.jpg?v=1788880882","url":"https:\/\/voomisupply.com\/products\/guhring-9007300053000-stub-drill-bit-5-30mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
