It measures 0.29 mm (0.0114 inches) in diameter with an overall length of 19.00 mm (0.75 inches). The bit is manufactured from high speed steel with an oxide coating for improved wear resistance. The standard 118-degree point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. With a two-flute spiral design and regular spiral type, this bit maintains accuracy in both blind hole and stack drilling applications. It is sized for fine-tolerance work, holding a diameter tolerance of h8 per ANSI, ISO, BS, and DIN standards.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and maintenance drilling in cast iron and steel workpieces. The 8xD flute-to-diameter ratio and 3.00 mm flute length make it appropriate for shallow-depth applications with a maximum drilling depth of 2.50 mm (0.098 inches). Typical use cases include precision hole drilling in metalworking, light manufacturing, and toolroom environments. The straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with benchtop drill presses, CNC machining centers, and hand-held power drills capable of accepting the 0.0114-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.29 mm (0.0114 inches) diameter with h8 tolerance for precision fitment\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry force\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for wear resistance\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design supports chip clearance in blind hole and stack drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks without modification\u003c\/li\u003e\n\u003cli\u003eMeets ANSI, ISO, BS, and DIN specification designations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron and steel workpieces.

Secure the straight-cylindrical shank fully in a properly rated drill chuck before operation. Power down and de-energize any machine spindle before changing bits. At this diameter, use appropriate low-speed, high-feed settings to avoid bit deflection or breakage, and confirm chuck runout is within acceptable tolerance for precision hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.29 mm (0.0114 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19.00 mm (0.75 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 16.00 mm (0.630 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0114 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.50 mm (0.098 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: 0.08 mm (0.0034 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5058391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728717021490,"sku":"5058391","price":118.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9437678eb2941250245f4e37764b6c5e_00bb1e0a-431a-4feb-9b5c-0d6b2e1f84a9.jpg?v=1788695413","url":"https:\/\/voomisupply.com\/products\/walter-titex-5058391-jobber-drill-bit-0-29mm-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
