It measures 3\/8 inch (9.53 mm) in diameter with an overall length of 8.819 inches (224 mm) and a flute length of 7.087 inches (180 mm). The bit features a 140-degree split point and a TiSiAlCrN coating that provides heat resistance and extended tool life at elevated cutting speeds. The straight-cylindrical shank measures 0.394 inches (10 mm) in diameter and 1.575 inches (40 mm) in length. This bit is part of the Series DC160-16-A1 and carries an h7 diameter tolerance for precision bore work. It is installed by machinists and tooling professionals on CNC machining centers and drill presses.\u003c\/p\u003e\n\u003cp\u003eThis extra length drill bit is suited for production and job-shop environments requiring deep-hole capability in tough materials. The 16xD flute-to-diameter ratio allows a maximum drilling depth of 6.496 inches (165 mm). Rated for use in alloy steels, titanium alloys, glass, and graphite, the 7684272 handles blind hole, cross hole, inclined hole exit, and stack drilling operations. Two right-hand flutes support efficient chip evacuation in these varied entry and exit conditions. No coolant-through capability is present, so external coolant or mist lubrication should be applied at the cutting zone during extended operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiSiAlCrN coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle optimized for self-centering and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003e16xD flute ratio supports maximum drilling depth of 6.496 inches (165 mm)\u003c\/li\u003e\n  \u003cli\u003eh7 diameter tolerance for precision fitment in close-tolerance bore applications\u003c\/li\u003e\n  \u003cli\u003eTwo right-hand flutes for efficient chip evacuation in blind and cross hole work\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards for interchangeability and dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 7684272 is compatible with primary workpiece materials including alloy steel and titanium alloy, with secondary capability in glass and graphite. It is designed for use in CNC machining centers, drill presses, and similar spindle equipment accepting a straight-cylindrical shank of 0.394 inches (10 mm) diameter. It falls under Series DC160-16-A1 from WALTER-TITEX.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with carbide cutting tools. The machine spindle and tool holder should be fully stopped and locked out before inserting or removing the bit. Verify shank runout and holder concentricity prior to operation, as carbide tooling is sensitive to lateral loading. Do not apply excessive feed rates on entry or exit to prevent chipping of the carbide cutting edge.\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\/8 inch (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8.819 inches (224 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 7.087 inches (180 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 6.496 inches (165 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\u003eDrill Point Length\u003c\/strong\u003e: 0.068 inches (1.73 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: 0.394 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.575 inches (40 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\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\u003eDiameter Tolerance\u003c\/strong\u003e: h7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 16xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: DC160-16-A1\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: 0.311 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: 7684272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51748207952178,"sku":"7684272","price":734.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5503e8d87858c98701d163e4b918465_a2996639-82d3-424a-bd5a-ef4bda745072.jpg?v=1788890353","url":"https:\/\/voomisupply.com\/products\/walter-titex-7684272-extra-length-drill-bit-3-8-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
