It features a 118-degree faceted point angle and a two-flute regular spiral configuration with web thinning to reduce thrust and improve chip evacuation. The overall length is 109 millimeters with a flute length of 69 millimeters, making it a compact, stiff tool suited for controlled-depth drilling in general-purpose applications. Licensed machinists, tool and die technicians, and maintenance mechanics are the typical users of this type of carbide jobber bit.\u003c\/p\u003e\u003cp\u003eThis bit is rated for primary use on aluminum and non-ferrous materials, corresponding to workpiece material code N under common tooling classification systems. The straight-cylindrical shank measures 7.37 millimeters in diameter with a shank length of 40 millimeters, fitting standard drill chucks and collet holders in both manual and CNC machine tools. The Series 732 designation places it within a general-purpose solid carbide jobber line conforming to DIN specification standards. Flute-to-diameter ratio is 5xD, and the diameter tolerance is held to h8 for consistent fit in tight-tolerance fixtures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous and general-purpose drilling\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning for reduced entry force and improved centering\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for aluminum and other materials in the N material group\u003c\/li\u003e\n\u003cli\u003eRegular spiral two-flute geometry promotes efficient chip clearance in shorter-run holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h8 diameter tolerance for accurate chuck or collet retention\u003c\/li\u003e\n\u003cli\u003eDIN-conforming Series 732 design for dimensional consistency across tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose solid carbide jobber drill compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank of approximately 0.2902 inches (7.37 millimeters) in diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of solid carbide drill bits should be performed by qualified machinists or maintenance technicians familiar with machine tool operation. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the bit from the chuck or collet. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Verify runout and chuck condition before drilling to protect the tool and maintain hole accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2902 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 109 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 69 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7.37 millimeters (0.2902 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 57.95 millimeters (2.281 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Code N)\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: 732\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 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: 9007320073700\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735216980274,"sku":"9007320073700","price":95.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ff889ec765c6c24e6dd7cf2a059df7c0_0cd7dcf8-fc50-42d9-80a6-23420cf21ad2.jpg?v=1788770457","url":"https:\/\/voomisupply.com\/products\/guhring-9007320073700-jobber-drill-bit-letter-l-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
