It measures 6.60 mm (0.2598 inches) in diameter with a standard 118-degree point angle and a black oxide coating that reduces friction and provides mild corrosion resistance. The overall length is 101.00 mm (3.98 inches), with a 63.00 mm (2.48 inches) flute length. A tapered web with web-thinning geometry reduces thrust at the cutting tip, making it a practical choice for production and maintenance drilling where consistent performance is required across multiple holes.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling steel and cast iron in both shop and field environments. It fits standard drill chucks via its straight cylindrical shank and is appropriate for use in drill presses, hand drills, and CNC machines running moderate feeds and speeds. The right-hand cut and regular spiral flute promote efficient chip evacuation in the materials it is rated for. It conforms to DIN 338, a widely recognized standard for jobber-length twist drills, making it a reliable specification-grade option for metalworking tradespeople, machinists, and maintenance technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6.60 mm (0.2598 inches) diameter with diameter tolerance of -0.0010 to 0.0000 inches for controlled fit\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced drilling thrust\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for friction reduction and mild surface protection\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction rated for steel and cast iron workpieces\u003c\/li\u003e\n\u003cli\u003eRegular spiral, right-hand cut with 2 flutes for consistent chip removal\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for jobber-length twist drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for general-purpose drilling in steel and cast iron.

Secure the workpiece and ensure the chuck is properly tightened before operation. Apply appropriate cutting fluid when drilling ferrous metals to extend tool life and maintain hole quality. Inspect the drill point for wear or chipping before each use and replace when cutting performance degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.60 mm (0.2598 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 101.00 mm (3.98 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 63.00 mm (2.48 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 38 mm (1.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2598 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0010 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CHICAGO-LATROBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47302\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51729312547122,"sku":"47302","price":66.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_2af6a0cc-34ac-4337-bd71-bc7832b08df9.jpg?v=1788702775","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47302-jobber-drill-bit-6-60mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
