Measuring 0.315 inches (8.00 mm) in diameter with an overall length of 3.0 inches, this bit features a 140-degree split point angle and a three-flute spiral configuration that promotes efficient chip evacuation and stable cutting action. The straight-cylindrical shank measures 0.315 inches in diameter with a shank length of 1.4173 inches. Built to DIN and ISO standards, this bit is suited for machinists, tool-and-die workers, and production drilling operations where dimensional accuracy and tool life are critical.\u003c\/p\u003e\u003cp\u003eThe 6618123 is engineered for drilling cast iron and steel in screw machine length applications, where compact overall length and rigidity are required. The 3xD flute-to-diameter ratio and universal tool performance rating make it appropriate for a wide range of production environments, from CNC machining centers to manual drill presses. The coated solid carbide construction extends tool life compared to high-speed steel alternatives, particularly in abrasive ferrous materials. This bit does not include coolant-through capability, making it best suited for external coolant or dry drilling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with coating for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree special point angle reduces thrust and improves centering accuracy\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral design promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 0.315 inches diameter for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003eScrew machine length geometry (3.0 inches overall) provides rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eMeets DIN and ISO standards with m7 diameter tolerance for precision fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling cast iron and steel workpieces.

Ensure the machine spindle and chuck are clean and properly seated before securing the straight-cylindrical shank to prevent runout. Power down and de-energize the machine completely before changing tooling. Carbide drill bits are brittle and should not be subjected to side loads or used in hand-held drilling applications where tool flex is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.315 inches (8.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 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: 0.0573 inches (1.46 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Special\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\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: 0.112 pounds\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: 6618123\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51748481106226,"sku":"6618123","price":109.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a24684ca3ba08641c979b28ea0c0a712_001f3d78-7436-436b-b0a7-c12d3f25b1cf.jpg?v=1788894249","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618123-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
