The bit measures 0.281 inches (9\/32 inch) in diameter with an overall length of 3.0 inches and a flute length of 0.843 inches. The 140-degree split point geometry reduces walking and improves chip evacuation at entry. Three spiral flutes and a straight-cylindrical shank make this bit compatible with standard drill chucks and CNC tool holders alike. It is part of the DC150-03-A0 series and carries a 3xD flute-to-diameter ratio, suited for screw machine applications where short, rigid setups are required. Licensed machinists, tool and die shops, and production drilling operations are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for production and job-shop environments running ferrous materials. Primary workpiece materials are cast iron and steel. The screw machine length format provides added rigidity compared to jobber-length bits, reducing deflection in high-feed applications. The coated solid carbide construction supports elevated cutting speeds while maintaining edge integrity over extended run cycles. It is appropriate for use on CNC machining centers, drill presses, and screw machines where repeatable hole quality and tool life are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and heat resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust force and minimizes entry walking\u003c\/li\u003e\n  \u003cli\u003eThree-flute spiral design improves chip flow and hole finish compared to two-flute configurations\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (3.0 inches overall) delivers greater stability in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends tool life in cast iron and steel drilling applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard ER collets and keyed drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets DIN and ISO standards for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with cast iron and steel workpieces in screw machine, CNC, and drill press setups. Part of the DC150-03-A0 series, covering drill bit sizes ranging from 0.250 to 0.300 inches (6.50 to 8.00 mm).

Ensure the shank seating surface and collet or chuck bore are clean and free of chips before securing the bit. Do not use this bit on non-ferrous or abrasive composite materials outside the rated workpiece material range. Verify spindle speed and feed rate against the manufacturer tooling data for the specific material and cutting condition before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.281 inches (9\/32 inch, 7.14 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: 0.843 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 Length\u003c\/strong\u003e: 0.0512 inches (1.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.843 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC150-03-A0\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.101 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6618112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51753753477426,"sku":"6618112","price":109.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a24684ca3ba08641c979b28ea0c0a712_81d30449-bfb2-4720-93b9-3a4c4154e572.jpg?v=1788940324","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618112-screw-machine-drill-bit-0-281-in","provider":"Voomi Supply","version":"1.0","type":"link"}
