Built to DC160-20-A1 series specifications, it features a 3\/16 inch (4.76 mm) cutting diameter with a 140-degree drill point angle for aggressive, self-centering entry. The TiSiAlCrN coating provides exceptional heat and wear resistance, making it well-suited for extended-run drilling operations. With a flute-to-diameter ratio of 20xD, this bit handles deep-hole applications where standard-length tooling cannot reach. It ships as a single unit and is used primarily by machinists, toolroom technicians, and precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for use in blind hole, cross hole, inclined hole exit, and stack drilling applications. Primary workpiece materials include alloy steels and titanium alloys. Secondary workpiece compatibility extends to glass and graphite. The coolant-through design supports internal coolant delivery, which is critical when drilling deep holes in heat-sensitive or gummy materials. The straight-cylindrical shank with an h7 diameter tolerance ensures consistent, secure seating in standard drill chucks and collet systems used in CNC machining centers and manual drill presses.\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 high heat tolerance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle for fast, accurate entry with reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e20xD flute-to-diameter ratio enables drilling depths up to 4.331 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; 2-flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eComplies with ANSI and ISO standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with alloy steel, titanium alloy, glass, and graphite workpieces.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet holder. Verify coolant-through passages are clear and coolant pressure is appropriate for the machine before initiating a drilling cycle. Avoid side loading or using this bit as a reamer, as carbide is brittle and susceptible to chipping under lateral forces.\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\/16 inches (4.76 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\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\u003eOverall Length\u003c\/strong\u003e: 5.906 inches (150 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.646 inches (118 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.331 inches (110 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.197 inches (5.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.102 inches (28 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.034 inches (0.87 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 20xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h7\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: DC160-20-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\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Inclined Hole Exit, Stack Drilling\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: 0.053 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: 7684296\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730937446706,"sku":"7684296","price":588.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a9f43049baed38ce5f4325f3476fc79_b1988dfd-4826-46ed-89c4-9066f0949d5a.jpg?v=1788725035","url":"https:\/\/voomisupply.com\/products\/walter-titex-7684296-extra-length-carbide-drill-bit-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
