It measures 6 mm in diameter with a 214 mm overall length and a 174 mm flute length, placing it in the DC160-25-A1 series with a 25xD flute-to-diameter ratio. The 140-degree point geometry reduces thrust load and improves self-centering on entry. A TiSiAlCrN coating provides heat resistance and extended tool life in high-temperature cutting conditions. This bit is designed for use by machinists and toolroom technicians working with CNC machining centers and drill presses requiring coolant-through capability.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole, cross hole, inclined hole exit, and stack drilling operations. Primary workpiece materials include alloy steel and titanium alloy. Secondary applications cover glass and graphite. The straight-cylindrical shank with h7 diameter tolerance ensures consistent runout in standard collet and chuck toolholding systems. It is a single-piece solid carbide construction — not brazed — making it appropriate for high-speed, high-precision production work where tool rigidity is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiSiAlCrN coating for elevated heat resistance and extended cutting life\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle reduces entry thrust and improves hole location accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers cutting fluid directly to the tip for deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003e25xD flute-to-diameter ratio supports maximum drilling depth of 165 mm\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, 2-flute design optimized for chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards for dimensional and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in alloy steel and titanium alloy workpieces as primary materials, with secondary suitability for glass and graphite.

Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Activate coolant-through supply before commencing the cut to prevent tip overheating in deep-hole operations. Do not exceed the rated maximum drilling depth of 165 mm without re-evaluating chip evacuation and coolant pressure for the specific setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 214 mm (8.425 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 174 mm (6.85 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 165 mm (6.496 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 Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.09 mm (0.043 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: 25xD\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 Diameter Tolerance\u003c\/strong\u003e: h7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiSiAlCrN\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: DC160-25-A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Glass, Graphite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.24 inches length x 0.71 inches width x 0.71 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.112 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: 7684347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51731111772466,"sku":"7684347","price":806.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a1ac1cdc1ccd0d00d85a5dd0d86d6d7_127c5dfd-cee7-4746-9490-54d382ce42ed.jpg?v=1788727088","url":"https:\/\/voomisupply.com\/products\/walter-titex-7684347-extra-length-drill-bit-6mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
