Built from solid carbide with a TiAlN (titanium aluminum nitride) coating, this bit delivers the heat and wear resistance required when drilling cast iron, non-ferrous metals, steel, and superalloys including titanium. The 140-degree split point geometry reduces thrust and walking at entry. At 5.2362 inches overall length with a 3.125-inch flute length, it fits standard jobber-length setups. The whistle notch shank at 0.6300 inches diameter provides positive retention in compatible tool holders. Coolant-through capability supports high-speed production runs where chip evacuation and thermal control are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole drilling and stack drilling applications across ferrous and non-ferrous workpiece materials including cast iron, steel, superalloys, and titanium. Assigned material codes K, N, P, and S confirm its broad compatibility across these material groups. The Series DC150 designation identifies it within the WALTER-TITEX line of solid carbide drills designed for production-rate machining. It is installed and operated by machinists and tool-and-die professionals using CNC machining centers, drill presses, and multi-spindle setups where precision bore tolerances and high feed rates are required.\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 high-heat cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and minimizes workpiece walking\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and thermal management during deep or stack drilling\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive retention and prevents shank rotation in tool holders\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry with 2 flutes promotes consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance m7 ensures precise bore sizing for close-tolerance applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; UNSPSC 23241634\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium (material codes K, N, P, S).

Ensure the machine spindle and tool holder are fully stopped and de-energized before loading or unloading the bit. Confirm the whistle notch is properly seated and the set screw is secured in the tool holder before operation. Avoid side loads or interrupted cuts that exceed the tool design parameters, as solid carbide is brittle and susceptible to chipping under shock loading.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.2362 inches (133.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.1250 inches (79.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.1250 inches (79.38 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6300 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8898 inches (48.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1140 inches (2.89 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\/Finish\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\u003eDiameter Tolerance\u003c\/strong\u003e: m7\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: 0.626 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: 6618454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51738830864690,"sku":"6618454","price":457.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fbb57bec91a870f2b0b64abb4463ad_9062dd83-5eac-4b6f-a07f-d1236e70cf33.jpg?v=1788805189","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618454-5-8-in-solid-carbide-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
