The bit is manufactured from high speed steel with an oxide coating that reduces friction and extends tool life in production environments. At 7.8 mm (0.3071 inches) in diameter, it carries a 118-degree standard point angle and a web-thinned, tapered web geometry that reduces thrust on entry. With an overall length of 117 mm (4-39\/64 inches) and a flute length of 75 mm (2-61\/64 inches), it fits standard drill chucks accepting a 0.3071-inch straight-cylindrical shank. Licensed machinists, maintenance technicians, and metal fabricators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for blind hole drilling and stack drilling operations on cast iron and steel workpieces. The Series A1211 designation places it within a high-performance jobber-length family conforming to ANSI, ISO, BS, and DIN standards. Its 8xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes up to 62 mm (2.4410 inches) maximum drilling depth, making it appropriate for both production and maintenance repair operations on machine tools, fabrication fixtures, and structural steel assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with oxide coating for reduced friction and extended service life\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for lower entry thrust on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSpiral regular flute, right-hand cut, optimized for cast iron and steel (material codes K and P)\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.3071 inches diameter fits standard three-jaw chucks and drill presses\u003c\/li\u003e\n  \u003cli\u003eMaximum drilling depth of 62 mm (2.4410 inches) with 8xD flute-to-diameter ratio for reliable chip clearance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI, ISO, BS, and DIN specification designations; diameter tolerance class h8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production drill bit for use in handheld drills, drill presses, and CNC machining centers accepting a straight-cylindrical shank in the 0.3000 to 0.3500 inch diameter range.\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 maintenance technicians familiar with metal-cutting operations. Secure the shank fully in the chuck and verify concentricity before starting the spindle. Power down and de-energize the machine before changing bits or clearing chips from the flutes. Use appropriate cutting fluid or coolant for the workpiece material to maintain tool life, noting that this bit does not support through-coolant delivery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.8 mm (0.3071 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 117 mm (4-39\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 75 mm (2-61\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 62 mm (2.4410 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3071 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42 mm (1.6530 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.34 mm (0.0923 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 Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1211\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO, BS, DIN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 5058832\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51747661807922,"sku":"5058832","price":18.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9437678eb2941250245f4e37764b6c5e_26b1427f-3de0-4bd9-a6b8-c9aeb7467bb4.jpg?v=1788884212","url":"https:\/\/voomisupply.com\/products\/walter-titex-5058832-jobber-drill-bit-7-8-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
