It carries a wire gauge size of 28, equivalent to 0.1405 inches in decimal, and features a 118-degree standard point angle for reliable entry and centering. The bit is manufactured from high speed steel with an oxide coating that reduces friction and extends service life under moderate cutting conditions. At 2.75 inches overall length with a 1.53125-inch spiral flute, it suits general-purpose hole-making in both production and maintenance environments. Licensed trades including machinists, millwrights, and industrial service technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit is built for blind hole drilling and stack drilling applications in ferrous materials, specifically cast iron and steel. The Series A1211 designation places it within a standardized jobber-length family conforming to ANSI and ISO standards, as well as BS and DIN specification designations. Its regular spiral flute geometry and web-thinned, tapered web configuration support chip evacuation in deeper holes up to a maximum drilling depth of 1.299 inches. The straight-cylindrical shank with an h8 diameter tolerance fits standard three-jaw drill chucks without adapter sleeves.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 28 (0.1405 inches decimal) straight-cylindrical shank matches chuck capacity on most benchtop and handheld drills\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose entry on cast iron and steel workpieces\u003c\/li\u003e\n  \u003cli\u003eOxide finish coating reduces heat buildup and friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements on blind hole and stack drilling setups\u003c\/li\u003e\n  \u003cli\u003e2-flute regular spiral geometry with an 8xD flute-to-diameter ratio promotes consistent chip clearance\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI, ISO, BS, and DIN standards for dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style jobber drill bit for use in standard three-jaw drill chucks accepting a 0.1405-inch straight-cylindrical shank.

Always use appropriate cutting fluid or coolant when drilling steel to preserve edge life, even though this bit does not support through-coolant. Wear eye protection and clamp workpieces securely before drilling. Inspect the cutting edges for wear between holes when stack drilling, as stacked stock accelerates edge degradation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.53125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.299 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1405 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.221 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: 0.0422 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDiameter Tolerance\u003c\/strong\u003e: h8\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\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 5058310\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51731832766770,"sku":"5058310","price":65.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9437678eb2941250245f4e37764b6c5e_289d5c56-23b7-48ae-b750-e62a491ddf65.jpg?v=1788735429","url":"https:\/\/voomisupply.com\/products\/walter-titex-5058310-jobber-drill-bit-wire-28-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
