With a 0.3437-inch (8.73 mm) cutting diameter and a 140-degree split-point geometry, it delivers fast, accurate hole entry with minimal walking. The multi-layer TiSiAlCrN\/AlTiN proprietary coating extends tool life when drilling abrasive and hard materials. At 3.504 inches overall length, this stub-length bit offers rigidity that reduces deflection in short-reach applications. Coolant-through capability allows high-speed cutting with effective chip evacuation. Licensed machinists, toolroom technicians, and production drilling operators are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance drilling in steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The screw machine (stub) length format makes it ideal for CNC machining centers, drill presses, and manual lathes where a shorter, stiffer tool is preferred over jobber-length alternatives. The Series DC160-03-A1 designation places it within a universal-advance performance tier, meaning it is optimized for a broad range of workpiece materials without requiring application-specific tooling changes. Right-hand cutting direction is standard for conventional spindle rotation setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and non-ferrous drilling\u003c\/li\u003e\n  \u003cli\u003eMulti-layer TiSiAlCrN\/AlTiN coating provides thermal and abrasion resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-feed drilling with active chip flushing\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length format delivers extra stiffness to minimize deflection\u003c\/li\u003e\n  \u003cli\u003eCompatible with steel, cast iron, aluminum, non-ferrous, and high-temp alloy workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and lathes accepting a 0.394-inch straight cylindrical shank. Primary workpiece materials include steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. Conforms to DIN and ISO standards for screw machine length drill bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a collet, drill chuck, or toolholder rated for the shank diameter before initiating spindle rotation. Verify that the machine spindle is fully stopped and the coolant system is primed before tool insertion when using the coolant-through feature. Do not exceed the maximum drilling depth of 1.378 inches per pass without retracting to clear chips, particularly in blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3437 inches (8.73 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.504 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.850 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.378 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.394 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eTool Material\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 Multi-layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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: Steel, Cast Iron, Aluminum and Non-Ferrous, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC160-03-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.148 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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7378203\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51744814399794,"sku":"7378203","price":264.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7195fed1a3acc9ede00fc3ffd865a23_00188e32-f4ad-427c-be76-41ea20403b2f.jpg?v=1788860838","url":"https:\/\/voomisupply.com\/products\/walter-titex-7378203-screw-machine-drill-bit-0-3437-in","provider":"Voomi Supply","version":"1.0","type":"link"}
