Built from solid carbide grade DK120, this bit delivers consistent performance in production and maintenance environments. It features a 118-degree faceted drill point with web thinning for reduced entry force and clean hole initiation. The bright, uncoated finish is well suited to non-ferrous applications where coating adhesion or heat buildup is not a primary concern. At 4.2 mm in diameter with a 2.953-inch overall length, this is a standard-reach tool for general-purpose drilling in light manufacturing, aerospace, and precision fabrication settings. Installation and use require no special tooling beyond a compatible collet or drill chuck.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in CNC machining centers, drill presses, and hand-held power tools where a straight-cylindrical shank is accepted. The Series 732 designation indicates a regular spiral, two-flute configuration with a 5xD flute-to-diameter ratio, providing adequate chip evacuation in typical aluminum and non-ferrous workpieces. The right-hand cut direction is standard for conventional drilling operations. This bit is appropriate for machinists, toolroom technicians, and precision manufacturing professionals working with aluminum (material code N) and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction, material grade DK120, for extended tool life in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e118-degree faceted point with web thinning for reduced thrust and clean hole entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design with 5xD ratio for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish optimized for aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0.000 to minus 0.012 mm for consistent hole accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber length drill bit for use in any machine or hand tool accepting a 4.2 mm straight-cylindrical shank.

Ensure the machine spindle is fully stopped and the tool is securely seated before beginning any drilling operation. Do not exceed the recommended drilling depth of 43 mm (1.693 inches) for this tool length. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before initiating the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75.00 mm (2.953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm (1.693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.20 mm (0.1654 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 32.00 mm (1.260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm (1.693 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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Grade DK120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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 (Material Code N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.000 to minus 0.012 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 732\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 9007320042000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730419319090,"sku":"9007320042000","price":42.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/32c0269b19ce11a77a0a9290c9ebbee4.jpg?v=1788717125","url":"https:\/\/voomisupply.com\/products\/guhring-9007320042000-jobber-drill-bit-4-2mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
