Built to the DC160 series standard, this bit features a 140-degree X treme Evo point geometry that supports fast, accurate entry with reduced thrust force. The 8.1 mm diameter corresponds to 0.3189 decimal inches, and the overall length is 89 mm (3.5039 inches). With a right-hand spiral flute design and a coated finish, the 7377171 delivers consistent performance in cast iron and steel workpieces. Licensed machinists, maintenance techs, and skilled tradespeople working with precision metalwork will find this bit suited to high-tolerance production and service drilling tasks.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for screw machine length applications where a compact, rigid tool is needed in confined or production-line setups. It is well-suited for drilling cast iron and steel in both shop environments and field maintenance scenarios. The 3xD flute-by-diameter ratio and 47 mm flute length support chip evacuation in moderate-depth holes up to 35 mm. The straight-cylindrical shank with a 10 mm diameter fits standard drill chucks and collet holders used in CNC machining centers, drill presses, and portable power tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e140-degree X treme Evo point for clean entry and accurate positioning in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and extended tool life in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eCoated finish reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes promote efficient chip removal during through and blind hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 10 mm shank compatible with standard chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN and ISO dimensional standards for consistent fit and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application drill bit for use in standard drill chucks and collet holders accepting a 10 mm straight-cylindrical shank, suitable for cast iron and steel workpiece materials as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with rotary cutting tool safety. Always ensure the machine spindle is fully stopped and power is disconnected before changing or inspecting the bit. Secure the shank firmly in the chuck or collet to the tool manufacturer's specified holding depth before beginning any drilling operation. Follow applicable shop safety standards and wear appropriate PPE, including eye protection, when operating drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.1 mm (0.3189 inches)\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: X treme Evo\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 89 mm (3.5039 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 47 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm (1.5800 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.47 mm\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: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eTool Performance\u003c\/strong\u003e: Universal Advance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\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: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.43 x 0.59 x 0.59 inches\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: 7377171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51729749770546,"sku":"7377171","price":211.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc29d20dd14dff40e8ee39f54234ed74.jpg?v=1788708934","url":"https:\/\/voomisupply.com\/products\/walter-titex-7377171-screw-machine-drill-bit-8-1mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
