Built from high speed steel with an oxide finish, this bit measures 0.8 mm (0.0315 inches) in diameter and has an overall length of 30.00 mm (1-3\/16 inches). The 118-degree standard point geometry and web-thinned, tapered web configuration reduce entry force and improve centering on contact. The two-flute spiral design promotes efficient chip evacuation. This bit is sized for tight-tolerance work, carrying a diameter tolerance of h8, and is suited for applications where controlled depth and clean hole entry are required.\u003c\/p\u003e\u003cp\u003eThe 5058442 is rated for use in cast iron and steel workpieces, making it appropriate for general-purpose machining, maintenance, and fabrication environments. Its straight-cylindrical shank seats directly in standard drill chucks without adapters. Typical applications include blind hole drilling and stack drilling operations. The flute-to-diameter ratio of 8xD and a maximum drilling depth of 8.70 mm (0.3430 inches) define its practical operating range. This bit is suited for use by machinists, maintenance technicians, and trade professionals working with steel and cast iron components in industrial or field settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.8 mm (0.0315 inch) diameter with h8 tolerance for close-fit hole work\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for wear resistance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web thinning for reduced thrust and improved centering\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design for effective chip clearing in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eRated for blind hole and stack drilling applications per Series A1211\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling cast iron and steel workpieces. Suitable for use in standard drill chucks accepting a 0.0315-inch straight shank.

Secure the shank fully in the drill chuck and verify runout before use. Power down and de-energize any machine tool before changing bits. Do not exceed the maximum drilling depth of 8.70 mm (0.3430 inches) to avoid bit deflection or breakage, especially at this small diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.8 mm (0.0315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30.00 mm (1-3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 20.00 mm (0.787 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 8.70 mm (0.3430 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: 0.24 mm (0.0094 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\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\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, BS, DIN\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: 5058442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51732769702194,"sku":"5058442","price":58.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9437678eb2941250245f4e37764b6c5e_264dd541-c35c-471e-8a8e-be7d2c1371cc.jpg?v=1788746567","url":"https:\/\/voomisupply.com\/products\/walter-titex-5058442-jobber-drill-bit-0-8mm-hss-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
