Built from solid carbide and coated with TiAlN, this bit handles cast iron, non-ferrous metals, steel, and superalloys including titanium. The 140-degree drill point angle and proprietary point geometry promote accurate entry and reduce walking on hard surfaces. At 4.055 inches overall length with a 1.875-inch flute length, the bit fits standard drill chucks and CNC machining centers. A whistle notch shank provides positive drive retention. Coolant-through capability supports chip evacuation and heat control in deep or blind hole drilling. Installation and operation are performed by machinists, tool-and-die technicians, and metalworking professionals.\u003c\/p\u003e\n\u003cp\u003eThe 6618380 is rated for blind hole drilling and stack drilling operations across a broad range of workpiece materials coded K, N, P, and S under ISO classification. The 5xD flute-to-diameter ratio and regular spiral flute geometry make this bit well suited for production environments where consistent hole quality is required in steel, cast iron, and titanium alloys. The DC150 series designation places this bit within a line engineered for high-performance drilling in ferrous and non-ferrous applications. The shank diameter of 0.394 inches and shank length of 1.575 inches are sized for compatibility with standard toolholding systems on CNC and manual machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating increases surface hardness and thermal resistance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with proprietary point geometry for accurate, self-starting entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and extends tool life in deep hole applications\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive drive and resists pullout in CNC toolholding systems\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole and stack drilling in cast iron, steel, non-ferrous metals, and superalloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron, non-ferrous metal, steel, and superalloy and titanium workpieces as defined by ISO material codes K, N, P, and S.

Verify that the toolholder and collet or chuck are clean and undamaged before seating the whistle notch shank. When using the coolant-through feature, confirm that coolant supply lines are connected and pressure is within the machine specification before initiating a cut. Do not use this bit in hand-held drill applications; it is intended for rigid machine tool setups only.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.055 inches (103 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.875 inches (47.63 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.394 inches (10.01 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.575 inches (40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0682 inches (1.73 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.875 inches (47.63 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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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: DC150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron; Non-Ferrous Metal; Steel; Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole; Stack Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI; ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.187 pounds\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: 6618380\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51742127522098,"sku":"6618380","price":184.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fbb57bec91a870f2b0b64abb4463ad_b07a8353-2769-4b6a-a9c3-55afc9ff0ad5.jpg?v=1788835432","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618380-3-8-inch-carbide-drill-bit-dc150","provider":"Voomi Supply","version":"1.0","type":"link"}
