Manufactured to DIN 6539 standards, this bit measures 0.4094 inches (10.40 mm) in diameter with a 140-degree split point and a web-thinned geometry that reduces thrust and improves chip evacuation. The overall length is 89.00 mm with a flute length of 43.00 mm. With a straight-cylindrical shank and two regular spiral flutes, this bit is built for use in CNC machining centers, drill presses, and screw machine setups where tight tolerances and consistent performance are required. Installation and use is handled by machinists and tool-and-die professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for right-hand cutting in cast iron and steel workpieces at a screw machine length classification, making it well suited for short-hole drilling applications where rigidity and accuracy are priorities. The 3xD flute-to-diameter ratio and parallel web configuration support chip clearance in deeper passes up to a maximum drilling depth of 1.0790 inches (27.40 mm). The submicron carbide grade and coated finish contribute to extended tool life in ferrous materials at elevated feed and speed conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron grain material grade for wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with SU point type and web-thinned geometry reduces entry thrust\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in cast iron and steel applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6539 specification for dimensional consistency and interchangeability\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 1.0790 inches (27.40 mm) with 3xD flute ratio for controlled chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces. Compatible with standard straight-shank drill chucks and collet systems accepting a 10.40 mm cylindrical shank. Fits drill presses, CNC machining centers, and screw machines configured for DIN 6539 series tooling. Diameter tolerance of plus 0.007 to plus 0.025 mm supports use in applications requiring consistent hole sizing within the 0.4000 to 0.4500 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the machine powered down and locked out per applicable machine safety procedures. Secure the straight-cylindrical shank fully within the chuck or collet to the recommended grip depth before operation. This bit does not support coolant-through delivery, so external coolant or cutting fluid should be applied at the point of cut when machining steel or cast iron. Inspect the cutting edges and coating condition before each use and replace the bit if chipping or wear is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4094 inches (10.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.0790 inches (27.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU\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: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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: Parallel, 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: plus 0.007 to plus 0.025 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6539\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1242\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: 9012420104000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727104082226,"sku":"9012420104000","price":321.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79e8bb79bf5d14140aab84ad80c69609.jpg?v=1788673386","url":"https:\/\/voomisupply.com\/products\/guhring-9012420104000-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
