Built to DIN 6535HA specification, this bit features a 140-degree Alpha 2 Plus Micro point and an AlCrN coating that extends tool life in abrasive and high-temperature cutting conditions. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is 74.00 mm. With a flute-to-diameter ratio of 8xD and a maximum drilling depth of 20.00 mm, the 6712939 is suited for precise, controlled hole-making in tight-tolerance work. It is installed and operated by machinists and CNC tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for blind hole drilling, stack drilling, and through-hole drilling across a range of workpiece materials. Primary materials include cast iron, non-ferrous metals, and steel. Secondary workpiece materials include cobalt, glass, graphite, iron alloys, nickel, titanium, and titanium alloys. The right-hand spiral flute geometry and web-thinned tapered web construction promote clean chip evacuation and reduced thrust force at small diameters. It fits machining centers, CNC drilling operations, and manual drill presses that accept a straight-cylindrical shank in the 3.00 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, material grade K30F, for rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlCrN coating provides oxidation resistance and extended tool life in ferrous and non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e140-degree Alpha 2 Plus Micro point reduces walking and improves entry accuracy in micro-diameter work\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust force and improves chip flow in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eRegular right-hand spiral flute with 8xD flute-to-diameter ratio supports deeper hole applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535HA specification for consistent shank geometry and tool holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in machining centers and CNC drill setups accepting a 3.00 mm straight-cylindrical shank per DIN 6535HA.

Ensure the tool holder collet or chuck is clean and free of debris before seating the straight-cylindrical shank. Verify spindle speed and feed rate settings are appropriate for the workpiece material before initiating a cut. Coolant-through is not supported on this bit; external coolant or mist lubrication should be used as required by the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Inch)\u003c\/strong\u003e: 3\/32 inch (0.0937 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 2.38 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\u003ePoint Type\u003c\/strong\u003e: Alpha 2 Plus Micro\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 24.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular, Right Hand)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide, Grade K30F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling, Through Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cobalt, Glass, Graphite, Iron Alloy, Nickel, Titanium, Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A6478TML\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6535HA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.23 inches L x 0.51 inches W x 0.51 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 6712939\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51731906265394,"sku":"6712939","price":199.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1fcbe730753f3d57c1440fc110c676cb_67408447-69a6-481b-bc86-819080ec40cb.jpg?v=1788736391","url":"https:\/\/voomisupply.com\/products\/walter-titex-6712939-micro-drill-bit-3-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
