Ground to a 140-degree drill point angle and finished with a TiNAl coating, this bit delivers extended tool life and thermal resistance in high-speed cutting environments. The straight-cylindrical shank measures 6.00 mm in diameter and 36.00 mm in length, with an overall length of 97.00 mm (3.819 inches). A two-flute geometry with an 8xD flute-to-diameter ratio supports efficient chip evacuation in both blind hole and stack drilling operations. Licensed machinists and CNC operators are the primary installers of this tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in blind hole and stack drilling applications across cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces. The TiNAl coating and WJ30TA carbide grade make it well-suited for production-level machining where heat generation and tool wear are primary concerns. It conforms to ANSI and ISO standards, fitting within the DC150-08-A1 series. Applicable in both manual and CNC machine setups where consistent hole diameter tolerance at m7 is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in WJ30TA grade for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTiNAl coating provides thermal barrier and extended cutting life at elevated spindle speeds\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust force and is optimized for hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for deep or high-feed drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chuck systems\u003c\/li\u003e\n  \u003cli\u003eSupports blind hole and stack drilling applications per tool specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DC150-08-A1 series jobber-length drill bit suitable for CNC machining centers and drilling machines configured for 6.00 mm straight-cylindrical shank tooling.

Ensure the collet or chuck bore is clean and within tolerance before seating the shank. Do not exceed the maximum drilling depth of 48.00 mm (1.890 inches) as specified for this tool. Verify coolant-through compatibility with the machine spindle before activating internal coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.50 mm (0.2165 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: 97.00 mm (3.819 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 57.00 mm (2.244 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 48.00 mm (1.890 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm (0.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.417 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.00 mm (0.039 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\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: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: WJ30TA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiNAl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC150-08-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.064 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.53 x 0.39 x 0.39 inches\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: 6618645\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51740884795698,"sku":"6618645","price":226.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74f65de149453cef1df499fb1e7ec970_5a0d1396-fe3e-4cd0-912a-9b0b1adf5383.jpg?v=1788828129","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618645-solid-carbide-jobber-drill-bit-5-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
