It carries a 118-degree standard point angle and a web-thinned, tapered web to reduce entry resistance and center the bit without a pilot hole. The spiral flute geometry runs in a right-hand cutting direction with a regular helix, evacuating chips efficiently during through-hole drilling. Overall length is 49.00 mm and the shank diameter measures 1.99 mm. Built to DIN 338, this bit is a general-purpose tool suited for production and maintenance drilling by machinists, millwrights, and tool-room technicians.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for drilling cast iron and steel workpieces in general-purpose applications. The 0.0783-inch decimal diameter falls in the 0.0500-to-0.1000-inch size range, making it a common choice for tapping prep, small clearance holes, and instrument or sheet-metal work where wire-gauge sizing is specified. The straight-cylindrical shank is compatible with standard drill chucks and collet holders used on bench drills, CNC machining centers, and handheld drill motors. Flute length is 24.00 mm, supporting a maximum drilling depth of 21.02 mm in a single pass.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 47 wire size  -  0.0783-inch decimal diameter, ground to DIN 338 specification\u003c\/li\u003e\n  \u003cli\u003eM2 high speed steel construction for durability across cast iron and steel workpieces\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  compatible with cutting oils and water-based coolants\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, regular helix  -  efficient chip evacuation in through-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement or stock drill bit for any drill chuck or collet holder accepting a 1.99 mm straight-cylindrical shank.

Ensure the drill chuck or collet is properly seated and tightened before operation, and confirm the workpiece is clamped securely. Apply an appropriate cutting fluid for steel drilling to extend tool life and maintain dimensional tolerance. Do not exceed the rated maximum drilling depth of 21.02 mm in a single pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 47\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0783 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 49.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.99 mm (0.0783 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 21.02 mm (0.83 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 Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9002050019900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739377500466,"sku":"9002050019900","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_f8628365-74ff-4d32-a5de-60912005ca35.jpg?v=1788813782","url":"https:\/\/voomisupply.com\/products\/guhring-9002050019900-no-47-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
