Built from high speed steel with an oxide coating for added surface hardness and corrosion resistance, this bit measures 4.9 mm (0.1929 inches) in diameter with an overall length of 86 mm (3.386 inches). The standard 118-degree split point and web-thinned tip reduce walking on entry and lower the thrust required to start a hole. A 2-flute spiral configuration evacuates chips efficiently during through-hole and blind-hole drilling. This bit is suited for production work, maintenance shops, and field repair scenarios where consistent hole quality in ferrous materials is required.\u003c\/p\u003e\n\u003cp\u003eThe 47282 is intended for drilling cast iron and steel in residential, commercial, and light industrial settings. The straight cylindrical shank fits standard drill chucks without adapters. With a flute length of 52 mm (2.047 inches) and a shank length of 34 mm (1.339 inches), the bit handles typical jobber-depth applications in structural steel, plate, and machined castings. It conforms to DIN 338 standards, making it a direct fit in applications where metric tooling specifications are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4.9 mm (0.1929 inch) diameter with a diameter tolerance of -0.0007 to 0.0000 inches for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for surface protection and reduced friction\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned tip for reduced entry thrust and improved centering\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral design for efficient chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 338 specification for metric jobber-length drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in cast iron and steel. Compatible with any drill chuck or machine tool accepting a 0.1929-inch straight cylindrical shank. Fits within the 4.00 to 5.00 mm drill bit size range category per DIN 338.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and used by machinists, maintenance technicians, pipefitters, and general tradespeople using handheld drills, drill presses, or CNC equipment. Secure the shank fully in the chuck before operation and verify chuck runout is within acceptable limits for the application. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, noting that this bit does not support coolant-through operation. Inspect the cutting edges for wear or chipping before each use and replace the bit if the tip is damaged to maintain hole quality and prevent workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.9 mm (0.1929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 86 mm (3.386 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 52 mm (2.047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 34 mm (1.339 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1929 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\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\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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.0007 to 0.0000 inches\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: 150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: CHICAGO-LATROBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CHICAGO-LATROBE","offers":[{"title":"Default Title","offer_id":51747233857842,"sku":"47282","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eca19afe150757905f09246344639f8_0e531aff-dcb5-409c-828a-b585ca4bad57.jpg?v=1788877870","url":"https:\/\/voomisupply.com\/products\/chicago-latrobe-47282-jobber-drill-bit-4-9mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
