It carries a TiAlN coating to resist heat and extend tool life under aggressive cutting conditions. The drill features a 140-degree point angle, a two-flute spiral configuration, and a whistle notch shank for secure toolholder engagement. With a 0.248-inch cutting diameter and an overall length of 3.5827 inches, this bit is suited for precision hole-making where tight tolerances and tool rigidity are critical. It is typically installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for blind hole applications and stack drilling operations where consistent chip evacuation and point stability are essential. The DC150 series designation places it within a purpose-engineered line for difficult-to-machine workpiece materials. The 5xD flute-to-diameter ratio supports adequate chip clearance at standard jobber depths. Coolant-through capability allows internal coolant delivery directly to the cutting zone, making it well-suited for machining centers equipped with through-spindle coolant systems. It is appropriate for both high-volume production and precision prototype work in aerospace, automotive, and general metalworking applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life by improving heat resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle suited for self-centering entry on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for heat control and chip flushing\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank ensures positive drive and prevents bit rotation in the holder\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole and stack drilling applications across a broad range of metallic workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification tooling replacement in the WALTER-TITEX DC150 series, suitable for CNC machining centers and drill presses with toolholders that accept a 0.315-inch whistle notch shank.

Ensure the spindle is fully stopped and machine power is in a safe state before loading or changing tooling. Confirm the toolholder bore matches the 0.315-inch shank diameter and that the whistle notch is properly aligned with the drive key before tightening. When using coolant-through capability, verify the machine spindle coolant system is enabled and operating at the pressure recommended by the machining center manufacturer before beginning the drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.248 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5827 inches (91 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.24 inches (31.5 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches (8 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: 0.0451 inches (1.15 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\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\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.24 inches (31.5 mm)\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel, Superalloys and Titanium\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: 0.088 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6618338\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51733157675314,"sku":"6618338","price":159.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fbb57bec91a870f2b0b64abb4463ad_31023ff6-a396-43e4-97c0-5969a5d971f1.jpg?v=1788752060","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618338-solid-carbide-jobber-drill-bit-0-248-in","provider":"Voomi Supply","version":"1.0","type":"link"}
