Built from solid carbide and coated with TiAlN for heat and wear resistance, this bit features a 140-degree split point for fast penetration and reduced walking on entry. The overall length is 3.228 inches (82 mm), the cutting diameter is 0.189 inches, and the shank diameter is 0.236 inches. A whistle notch shank ensures positive drive and accurate concentricity in compatible chucks and collets. Installation and setup are handled by machinists and tool-room technicians working in CNC and manual drilling applications.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole drilling and stack drilling operations where accurate depth control and chip evacuation matter. The two-flute spiral design with a 5xD flute-to-diameter ratio promotes efficient chip removal even in tougher alloys. Coolant-through capability supports high-speed operations in production environments where heat buildup is a concern. The DC150 series targets applications in aerospace, automotive, and general metalworking where superalloys and titanium are common workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiAlN coating for extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with proprietary point geometry reduces thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed and high-feed drilling operations\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive drive and prevents slippage under load\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral configuration with 5xD ratio for efficient chip evacuation in blind holes and stack drilling\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; diameter tolerance held to m7\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and manual machines equipped with chucks or collets accepting a 0.236-inch shank.

Secure the whistle notch shank firmly in a compatible collet or chuck to the tool manufacturer's recommended clamping procedure. When using coolant-through capability, verify that the machine spindle and toolholder are set up to deliver coolant at the appropriate pressure and flow rate. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and susceptible to damage from improper handling or interrupted cuts at incorrect feeds and speeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.189 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\u003eOverall Length\u003c\/strong\u003e: 3.228 inches (82 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.945 inches (24 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.236 inches (5.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.417 inches (36 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.945 inches (24 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.034 inches (0.87 mm)\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: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel, Superalloys and Titanium\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\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: 0.066 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: 6618319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51737774129458,"sku":"6618319","price":136.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fbb57bec91a870f2b0b64abb4463ad_4465c293-d522-4117-a955-0e921ee73118.jpg?v=1788793443","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618319-jobber-length-drill-bit-0-189in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
