It measures 4.65 mm in diameter (0.1831 inch) with a 140-degree drill point angle and an overall length of 74 mm (approximately 2.91 inches). The bit carries a dual-layer TiSiAlCrN\/AlTiN coating that extends tool life in abrasive and high-temperature cutting conditions. A coolant-through design channels cutting fluid directly to the cutting zone, improving chip evacuation and thermal management. Installed by machinists and tool-and-die professionals, this bit is suited for production environments where consistent hole quality and tool longevity are required.\u003c\/p\u003e\u003cp\u003eThis drill bit performs across a broad range of workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium. Its 5xD flute-to-diameter ratio and two-flute spiral design support a maximum drilling depth of 29 mm. It handles blind holes, cross holes, inclined hole exits, and stack drilling operations. The straight-cylindrical shank measures 6 mm in diameter and 36 mm in length (approximately 1.42 inches), making it compatible with standard collet chucks and drill holders used in CNC machining centers and conventional drill presses. The bit conforms to ANSI and ISO standards and carries material grade WJ30ET.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eDual coating system (TiSiAlCrN\/AlTiN) for thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for active chip evacuation and heat control at depth\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle reduces thrust and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eHandles blind holes, cross holes, inclined hole exits, and stack drilling\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; material grade WJ30ET for consistent metallurgical quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the WALTER-TITEX Series DC160 product line.

Ensure the collet or chuck is clean and properly torqued to the holder specification for the machine in use. Coolant-through operation requires a compatible spindle and coolant system; verify pressure and flow settings before running the tool. Inspect the cutting edges for wear or chipping before each use and replace the bit when the coating shows significant breakdown or dimensional drift is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.65 mm (0.1831 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm (approximately 2.91 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 29 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.42 inches)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: WJ30ET\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiSiAlCrN \/ AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Applications\u003c\/strong\u003e: Blind Hole, Cross Hole, Inclined Hole Exit, Stack Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC160\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.019 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.66 inches (L) x 0.47 inches (W) x 0.47 inches (H)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7377448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51748736270642,"sku":"7377448","price":241.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2caaf6b3e9d6bc28726be3837d770e0_1061ad6f-cc13-4997-8221-ef8005b4d2e2.jpg?v=1788897538","url":"https:\/\/voomisupply.com\/products\/walter-titex-7377448-carbide-drill-bit-4-65mm-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
