It measures 23\/32 inches (0.7188 inches) in diameter with a 5-inch overall length and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup. The 130-degree split point provides accurate self-centering and minimizes walking on entry. Constructed from cobalt vanadium high speed steel, this bit handles elevated cutting temperatures better than standard HSS tooling, making it suitable for harder or more abrasive workpiece materials. It is installed and used by machinists, tool-and-die tradespeople, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron, stainless steel, hardened steels, non-ferrous metals, and other hard materials where standard HSS bits wear prematurely. The screw machine length format provides added rigidity compared to jobber-length bits, making it a preferred choice for drill press, CNC, and lathe turret work. It belongs to the Walter Titex Series A1148, which is a universal-performance line built to DIN and ISO standards. Maximum drilling depth is 1.8 inches (45.00 mm), making it appropriate for moderate-depth bores in production or maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt vanadium high speed steel construction resists heat and wear in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree split point with web-thinning for accurate entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute design with tapered web improves chip flow and reduces clogging\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids across multiple material types\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with straight-cylindrical shank for standard drill chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series A1148 screw machine length drill bit conforming to DIN, ISO, and BS standards. Compatible with any drill press, CNC machine, lathe turret, or hand drill equipped with a chuck that accepts a straight-cylindrical shank of 23\/32 inches diameter. Suitable for primary workpiece materials including cast iron, hard materials, non-ferrous metals, stainless steel, and steel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the shank fully in the drill chuck and verify runout before drilling. Use an appropriate cutting fluid or coolant for the workpiece material, particularly when drilling stainless steel or hardened alloys, to extend tool life and maintain surface finish. This bit does not support through-coolant and relies on external fluid application. Ensure the workpiece is firmly clamped before starting the cut to prevent bit walking or workpiece movement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 23\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.7188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-33\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.1680 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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: -0.00130 to 0.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 5153744\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51741738238258,"sku":"5153744","price":115.29,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_5a1dd8ec-e392-4024-bbda-403283861daf.jpg?v=1788833211","url":"https:\/\/voomisupply.com\/products\/walter-titex-5153744-screw-machine-drill-bit-23-32-in","provider":"Voomi Supply","version":"1.0","type":"link"}
