The bit measures 0.228 inches in diameter with an overall length of 3.228 inches and carries a TiAlN coating that extends tool life under elevated cutting temperatures. The 140-degree split point geometry reduces walking and thrust requirements at entry. Coolant-through capability supports chip evacuation in blind hole applications. This is a tool for professional machinists, metalworking shops, and maintenance technicians running CNC or manual drilling operations.\u003c\/p\u003e\n\u003cp\u003eThe 6618332 belongs to the WALTER-TITEX DC150 series, engineered for blind hole drilling and stack drilling applications. The whistle notch shank with a 0.236-inch shank diameter provides positive retention in standard collet and chuck systems. With a flute-by-diameter ratio of 5xD and a right-hand spiral flute, this bit maintains chip flow in interrupted cuts and multi-layer stack setups. It is suited for production environments where consistent hole tolerance and tool life are critical across ferrous and non-ferrous 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 abrasive and high-temperature materials\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary drill point reduces entry deflection and improves hole positioning accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and thermal management in blind hole drilling\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive drive engagement in collet and chuck systems\u003c\/li\u003e\n  \u003cli\u003e5xD flute-by-diameter ratio supports deep blind hole and stack drilling operations\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards with m7 diameter tolerance for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual drilling equipment where a 0.236-inch shank collet or chuck is available.

Confirm collet or chuck bore matches the 0.236-inch shank diameter before seating the bit. Use the whistle notch feature with an appropriate retention system to prevent pull-out under cutting loads. Verify coolant-through passages are clear and system pressure is set per machine specifications before running production.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.228 inches\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: 1.14 inches (28.96 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.14 inches (28.96 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\u003eDrill Point Length\u003c\/strong\u003e: 0.042 inches (1.06 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: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eDiameter Tolerance\u003c\/strong\u003e: m7\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\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: 0.062 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: 6618332\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51731882901810,"sku":"6618332","price":135.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fbb57bec91a870f2b0b64abb4463ad_724d3810-8cb9-4067-b821-9d6d8e979ba8.jpg?v=1788736039","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618332-solid-carbide-jobber-drill-bit-0-228-in","provider":"Voomi Supply","version":"1.0","type":"link"}
