Built to Series DC150 standards, it features a 140-degree point angle with a proprietary point geometry and a TiAlN (titanium aluminum nitride) coating that extends tool life under heat and abrasion. The drill measures 0.2830 inches in diameter with an overall length of 3.5827 inches (91.00 mm). The whistle notch shank provides secure tool holding in compatible chucks and toolholders. Two spiral flutes with a regular helix promote efficient chip evacuation. Coolant-through capability supports sustained performance in deep or stacked applications. This drill is installed by machinists, maintenance technicians, and toolroom professionals.\u003c\/p\u003e\n\u003cp\u003eThe 6618350 is suited for blind hole drilling and stack drilling operations across a range of workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium. The 5xD flute-to-diameter ratio supports drilling depths up to 1.4150 inches (35.94 mm). Its TiAlN coating and carbide substrate make it particularly effective in high-speed or dry cutting conditions where tool wear is a primary concern. This drill is applicable in CNC machining centers, drill presses, and manual machine setups where a whistle notch shank interface is used.\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 enhances heat resistance and extends tool life in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e140-degree proprietary point angle reduces thrust force and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing in blind hole and stack drilling\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive drive and resists pullout in high-torque applications\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 toolholders and chucks accepting a 0.3150-inch (8.00 mm) whistle notch shank. Compatible with workpiece materials coded K (cast iron), N (non-ferrous metals), P (steel), and S (superalloys and titanium) per ISO material classification. Drill bit size falls within the 0.2500 to 0.3000 inch range of the DC150 series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the whistle notch shank fully in the toolholder and confirm the drive key engages the flat before tightening. When coolant-through capability is used, verify that the machine coolant supply pressure and flow rate are compatible with the toolholder and spindle interface before running the program.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2830 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: 3.5827 inches (91.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4150 inches (35.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.4150 inches (35.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4170 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0516 inches (1.31 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 Helix\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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\u003eDrill Bit Diameter 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\u003eSpecification Designation\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.106 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 0.5 inches W x 0.5 inches H\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: 6618350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51749599346994,"sku":"6618350","price":160.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fbb57bec91a870f2b0b64abb4463ad_bf1cd56d-1d71-436a-b486-6ad9a15b98e5.jpg?v=1788908158","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618350-solid-carbide-jobber-drill-0-2830-in","provider":"Voomi Supply","version":"1.0","type":"link"}
