Built to DIN 6539 standards with a micrograin carbide grade, it delivers consistent performance in general-purpose applications. The bit features a 118-degree faceted point angle with web thinning for easier penetration and reduced thrust. At 0.2421 inches (Letter C) in diameter, it is sized for tight-tolerance work with a h8 diameter tolerance rating. Machinist and tool-and-die professionals working with CNC equipment and screw machines rely on this series for repeatable accuracy.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling aluminum and similar non-ferrous materials in light manufacturing and job-shop settings. Its stub-length body provides added rigidity compared to jobber-length bits, reducing deflection in short, controlled drilling cycles. The straight-cylindrical shank fits standard drill chucks and collet systems without modification. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 0.857 inches, it is well matched for shallow-to-moderate depth holes in production runs or precision fixturing work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eDIN 6539 compliant, Series 730 designation for consistent manufacturing tolerances\u003c\/li\u003e\n  \u003cli\u003eh8 shank diameter tolerance for accurate chuck and collet seating\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for aluminum and general-purpose non-ferrous drilling\u003c\/li\u003e\n  \u003cli\u003eStub-length body increases rigidity and minimizes bit deflection\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 for use in CNC machining centers, screw machines, and manual drill presses equipped with standard straight-shank chucks or collet holders accepting a 6.15 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation and verify runout before beginning a drilling cycle. Carbide tooling is brittle and susceptible to breakage from side loading or interrupted cuts — avoid lateral forces during drilling. Power down or e-stop the spindle fully before changing or inspecting the bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2421 inches (Letter C)\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: 0.857 inches (21.78 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.15 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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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: 0.023 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: 9007300061500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748105912626,"sku":"9007300061500","price":67.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e1921a5ddc478e7ad7240d9f7bd1ef7a_dbd8285e-5051-44d8-b12a-8d95acc96978.jpg?v=1788889116","url":"https:\/\/voomisupply.com\/products\/guhring-9007300061500-carbide-stub-drill-bit-0-2421-in","provider":"Voomi Supply","version":"1.0","type":"link"}
