Built from high speed steel with an oxide coating, it features a 118-degree standard point angle and a web-thinned, tapered-web geometry that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 5\/16 inches in diameter, and the overall length is 4-19\/32 inches. With two right-hand spiral flutes and a regular spiral type, this bit is engineered for consistent, repeatable results in both blind hole and stack drilling applications. It meets ANSI and ISO standards and carries an h8 diameter tolerance for precise fitment.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for general-purpose and high-performance work in residential and commercial maintenance, mechanical contracting, and fabrication environments. Its Series A1211 designation places it in a well-established line of straight-shank jobber drills. Typical applications include drilling into cast iron pipe fittings, structural steel, and plate stock. The 8xD flute-by-diameter ratio supports deeper hole entry with adequate chip clearance. It is appropriate for use in handheld drills, drill presses, and CNC machining centers where a 5\/16-inch straight shank is accepted.\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 wear resistance\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered-web geometry for lower entry thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flutes for efficient chip removal in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole and stack drilling tool applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards with h8 diameter tolerance for dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through feature not required, compatible with standard dry or flood-coolant setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose OEM-style replacement or service drill bit for use in any drill press, hand drill, or CNC spindle accepting a 5\/16-inch straight-cylindrical shank.

Secure the shank firmly in a properly sized chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Ensure spindle speed is appropriate for the workpiece material and bit diameter per standard cutting data references. Do not exceed the maximum drilling depth of 2.441 inches in a single pass without clearing chips to prevent bit deflection or breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-19\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.653 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.441 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0939 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\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003eDiameter Tolerance\u003c\/strong\u003e: h8\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: 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: 5058791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728782065970,"sku":"5058791","price":18.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9437678eb2941250245f4e37764b6c5e_d3c09002-4fee-4738-891a-6fe53903b29c.jpg?v=1788696167","url":"https:\/\/voomisupply.com\/products\/walter-titex-5058791-jobber-drill-bit-5-16-in-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
