It features a 6.60 mm cutting diameter, a 140-degree split point for reduced thrust and accurate self-centering, and a dual-layer AlTiN\/TiSiAlCrN coating that delivers oxidation resistance and extended tool life at elevated cutting temperatures. With an overall length of 91.00 mm, a 53.00 mm flute length, and a 5xD flute-to-diameter ratio, this drill is suited for aggressive feed rates where tool rigidity and chip evacuation are critical. Coolant-through capability further supports thermal control and chip flushing in deep-hole applications. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill is designed for use in blind hole, cross hole, inclined hole exit, and stack drilling operations. It performs across a range of workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium, corresponding to ISO material codes K, N, P, and S. The straight-cylindrical shank measures 8.00 mm in diameter and 36.00 mm in length, making it compatible with standard collet chucks and drill chucks found on CNC machining centers, drill presses, and multi-spindle setups. Its m7 diameter tolerance ensures consistent fit and repeatable bore sizing in precision applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and thermal stability at high cutting speeds\u003c\/li\u003e\n  \u003cli\u003eAlTiN\/TiSiAlCrN dual-layer coating for extended wear resistance and heat protection\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and promotes accurate hole location\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design flushes chips and controls heat in blind and deep-hole operations\u003c\/li\u003e\n  \u003cli\u003eSuitable for blind hole, cross hole, inclined exit, and stack drilling applications\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO standards; material grade WJ30ET\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 7377494 is rated for cast iron (K), non-ferrous metals (N), steel (P), and superalloys and titanium (S) workpieces. It fits standard 8.00 mm straight-cylindrical collet and drill chuck toolholders. Drill bit diameter falls within the 6.00-7.00 mm size range and the 0.2500-0.3000 decimal inch range per its series classification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation of this drill should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and all axis motion is disabled before changing or setting tools in the toolholder. Verify collet or chuck runout is within acceptable tolerance before operation, as excess runout accelerates carbide wear and can cause tool breakage. Coolant supply lines should be confirmed active and at adequate pressure before initiating coolant-through drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 6.60 mm (0.2598 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Grade WJ30ET)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN \/ TiSiAlCrN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.20 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\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\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DC160\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: 0.04 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: 7377494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730296701234,"sku":"7377494","price":270.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d9b6bc5c3486c1c38a6d0034a93cd6c_24bcca37-4c11-4b79-884f-ff45aa73087c.jpg?v=1788714863","url":"https:\/\/voomisupply.com\/products\/walter-titex-7377494-carbide-jobber-drill-6-60mm-dc160","provider":"Voomi Supply","version":"1.0","type":"link"}
