It features a 6.40 mm (0.2520 inch) diameter, a 140-degree split point, and a TiNAl coating that extends tool life in demanding production environments. With three regular spiral flutes and a 3 inches overall length, this bit delivers fast chip evacuation and stable cutting action at shorter working depths. It is sized for precision work within the DC150-03-A0 series and carries a Drill Bit Diameter Tolerance of m7, making it suitable for tight-tolerance holes. Machinists and toolroom technicians in metalworking shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for screw machine length applications where rigidity and accuracy matter more than reach. Its straight cylindrical shank (0.3150 inch diameter) fits standard drill chucks and collet holders without modification. The 0.7560-inch flute length supports a maximum drilling depth of 0.7560 inches, making it well suited for short, precise through-holes and blind holes in steel and cast iron workpieces. The 3xD flute-to-diameter ratio and universal tool performance classification make it a practical choice for CNC machining centers, drill presses, and screw machines running production runs on ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and heat resistance for ferrous metal drilling\u003c\/li\u003e\n  \u003cli\u003eTiNAl coating improves wear resistance and reduces heat buildup at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e140-degree special point angle reduces thrust force and minimizes workpiece deformation on entry\u003c\/li\u003e\n  \u003cli\u003eThree-flute design improves chip evacuation and surface finish compared to standard two-flute bits\u003c\/li\u003e\n  \u003cli\u003em7 diameter tolerance supports tight-tolerance hole requirements without reaming in many applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN and ISO standards for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DC150-03-A0 series screw machine length drill bit for use in steel and cast iron workpieces.

Before mounting, ensure the machine spindle and chuck are clean and free of debris to maintain runout tolerances. Always power down and lock out the machine before changing tooling. Do not exceed the manufacturer-rated speeds and feeds for solid carbide tooling in ferrous materials, and verify shank seating depth in the holder before starting a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.40 mm (0.2520 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.7560 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.7560 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 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\u003eDrill Point Length\u003c\/strong\u003e: 1.16 mm (0.0459 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: TiNAl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Special\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC150-03-A0\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: 0.095 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3 inches L x 0.38 inches W x 0.38 inches H\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: 6618103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51752527790386,"sku":"6618103","price":109.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a24684ca3ba08641c979b28ea0c0a712_20c66c8d-56b9-4402-8af3-be77b663e59e.jpg?v=1788928904","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618103-screw-machine-drill-bit-6-40mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
