Built to Series DC150-03-A0 specifications, it features a 140-degree point angle and a TiNAl (titanium aluminum nitride) coating that extends tool life under demanding conditions. The bit measures 13\/32 inches (0.4062 inches decimal) in diameter with a 4-inch overall length, making it well suited for short-hole drilling applications where rigidity and accuracy are critical. Licensed machinists, tool-and-die technicians, and industrial maintenance professionals are the primary users of this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for universal tool performance and is optimized for primary workpiece materials including steel and cast iron. Its screw machine length profile — shorter than jobber length — provides added rigidity and reduced deflection in CNC machining centers, drill presses, and manual machine tools. The 3-flute, regular spiral flute geometry improves chip evacuation and supports higher feed rates compared to standard 2-flute designs. The straight cylindrical shank (0.4720 inches diameter) fits standard collet chucks and drill chucks without modification. Maximum drilling depth is 1.2180 inches, consistent with the 3xD flute-by-diameter ratio of this series.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiNAl coating extends tool life and reduces built-up edge on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree special point angle improves self-centering and reduces thrust load\u003c\/li\u003e\n  \u003cli\u003e3-flute regular spiral geometry enhances chip removal and allows higher feed rates\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (4 inches OAL) provides superior rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank fits standard collet and drill chuck toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN and ISO standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel and cast iron workpieces as an OEM-style replacement or standard tooling selection within the WALTER-TITEX DC150-03-A0 series, covering drill bit diameters in the 0.4000 to 0.4500 inch range (9.50 to 11.00 mm).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit should be installed by a qualified machinist or maintenance technician familiar with rotating cutting tool safety. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or chuck bore compatibility with the 0.4720-inch shank diameter before seating the bit. Do not exceed the recommended maximum drilling depth of 1.2180 inches per pass without retracting to clear chips, as this bit does not support coolant-through 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: 13\/32 inches (0.4062 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 10.32 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.2180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.2180 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.7717 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: 0.0739 inches (1.88 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: Regular 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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiNAl\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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 Bit Size Range\u003c\/strong\u003e: 0.4000 to 0.4500 inches (9.50 to 11.00 mm)\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: 0.265 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 0.38 inches W x 0.38 inches H\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: 6618151\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51732625129778,"sku":"6618151","price":131.74,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a24684ca3ba08641c979b28ea0c0a712_f768fe7d-89d9-4d7e-9956-4b1a56621f93.jpg?v=1788745152","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618151-screw-machine-drill-bit-13-32-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
