Measuring 0.147 inches (wire size 26) in diameter, the bit features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves centering accuracy. With a 2-flute spiral configuration and a straight-cylindrical shank, it fits standard drill chucks and CNC toolholders without adapters. Solid carbide construction provides the rigidity and wear resistance required when drilling aluminum and other non-ferrous materials at elevated speeds. This bit is manufactured to DIN 6539 standards and carries a K40 carbide grade designation, confirming consistent dimensional and metallurgical quality.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized and configured for production machining, toolroom work, and precision fabrication applications. Its stub-length body reduces deflection compared to jobber-length bits, making it well suited for numerically controlled drilling operations, jig drilling, and tight-tolerance hole work in aluminum and similar workpiece materials. The overall length of 2.047 inches keeps the cutting zone close to the spindle nose, improving rigidity in high-RPM setups. Machinists, tool and die makers, and CNC operators working in job shops or manufacturing cells are the primary users of this bit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in K40 grade for wear resistance and dimensional stability\u003c\/li\u003e\n\u003cli\u003e118-degree faceted drill point with web thinning for reduced thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length body minimizes deflection during high-speed drilling\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral geometry promotes chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and ER collets without adapters\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 6539 standards with a diameter tolerance of +0.000 to -0.010 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide stub drill for use in standard drill chucks, ER collet systems, and CNC machining centers that accept straight-cylindrical shank tooling in the 3.73 mm shank diameter range.

Ensure the spindle is fully stopped and the machine is powered down or in safe mode before changing tooling. Secure the shank fully within the collet or chuck to the recommended grip depth to prevent pullout under cutting loads. Do not exceed the maximum drilling depth of 0.567 inches per pass without retracting to clear chips, as solid carbide is brittle and susceptible to breakage under lateral loading or chip packing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.147 inches (Wire Size 26)\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide (K40)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eFlute Length\u003c\/strong\u003e: 0.787 inches (20.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.047 inches (52.00 mm)\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: 3.73 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.567 inches (14.41 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\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\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.010 mm\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: 2463\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9024630037300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732021117234,"sku":"9024630037300","price":47.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb3bd143f28962c2d256fb85eb88b908_af46a323-cf1f-439b-9530-dcd156749bbc.jpg?v=1788738235","url":"https:\/\/voomisupply.com\/products\/guhring-9024630037300-stub-drill-bit-0-147-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
