Built to Series DC150-08-A1 specifications, it features a 3.50 mm diameter, a 140-degree split point, and a TiNAl (titanium aluminum nitride) coating that extends tool life under high heat and abrasion conditions. The straight cylindrical shank measures 6 mm in diameter. With a 2-flute right-hand cutting geometry and coolant-through capability, this drill maintains chip evacuation and thermal control across tough workpiece materials. It is installed by machinists, tooling technicians, and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis drill is suited for blind-hole drilling and stack drilling operations. Compatible primary workpiece materials include cast iron, aluminum and non-ferrous metals, steel, and high-temperature alloys, corresponding to material codes K, N, P, and S. The 8xD flute-to-diameter ratio supports deeper penetration relative to bit diameter. With an overall length of 74.00 mm (2.913 inches) and a maximum drilling depth of 28.00 mm (1.102 inches), it fits standard CNC machining centers and drill presses equipped for small-diameter carbide tooling. Drill bit grade is WJ30TA.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiNAl coating for extended wear resistance in abrasive and high-temp materials\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces thrust and improves self-centering at entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design promotes chip flushing and heat management in deep blind holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 2-flute geometry optimized for cast iron, steel, aluminum, and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; tolerance class m7 on drill diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and automated drilling equipment accepting a 6 mm straight shank. Suitable for workpiece materials classified under ISO codes K (cast iron), N (aluminum and non-ferrous), P (steel), and S (high-temperature alloys). Part of the Walter DC150-08-A1 series, sized within the 3.00 mm to 4.00 mm drill diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists or CNC technicians with the machine in a fully stopped and locked-out state per applicable machine safety standards. Secure the shank fully in the collet or chuck to the recommended grip depth before operation. Verify coolant-through lines are clear and properly connected before running the spindle. Do not exceed the manufacturer-rated maximum drilling depth of 28.00 mm per cycle without re-evaluating chip load and coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.50 mm (0.1378 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\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiNAl\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: WJ30TA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm (2.913 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 34.00 mm (1.339 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 28.00 mm (1.102 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.236 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.417 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.64 mm (0.025 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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: m7\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: 0.044 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.62 inches L x 0.39 inches W x 0.39 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: 6618620\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51739926495538,"sku":"6618620","price":226.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74f65de149453cef1df499fb1e7ec970_0aee24a7-8042-439a-b9b3-4f088bd6ac8c.jpg?v=1788820455","url":"https:\/\/voomisupply.com\/products\/walter-titex-6618620-solid-carbide-jobber-drill-3-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
