Built to the A1247 series specification, it features a 4.8 mm (0.189 inch) diameter with a parabolic flute geometry and a 130-degree split point. The oxide coating improves wear resistance and heat dissipation during extended cutting cycles. With a straight-cylindrical shank and web-thinned, tapered web construction, this bit delivers consistent entry and chip evacuation in blind-hole and stack-drilling applications. It is typically installed by machinists, tool and die specialists, and maintenance professionals working in metal fabrication environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in cast iron, non-ferrous metals, stainless steel, carbon steel, superalloys, and titanium. The parabolic flute design supports efficient chip removal at higher feed rates, reducing heat buildup in difficult-to-machine materials. The 8xD flute-to-diameter ratio allows for deeper drilling relative to diameter, making it appropriate for production environments where consistent hole quality is required. Blind-hole and stack-drilling applications are specifically supported by the split-point geometry and web thinning.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.8 mm (0.189 inch) diameter with straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003cli\u003e130-degree split point reduces walking and improves entry accuracy without center-punching\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes rapid chip evacuation in deep or stacked workpieces\u003c\/li\u003e\n\u003cli\u003eCobalt substrate with oxide coating for improved hardness and heat resistance in ferrous and high-alloy materials\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces thrust force at the cutting tip\u003c\/li\u003e\n\u003cli\u003eRated for blind-hole and stack-drilling tool applications per series specification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance OEM-style jobber-length drill bit for use with standard straight-shank drill chucks and collets compatible with 0.189 inch shank diameter tooling.

Secure the shank fully in a compatible drill chuck or collet before operation, and verify runout is within acceptable tolerance for the application. Power down and de-energize the machine spindle before changing tooling. Do not exceed the recommended maximum drilling depth of 44 mm (1.732 inches) for this bit diameter and flute configuration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.8 mm (0.189 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 86 mm (3-25\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 52 mm (2-3\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 34 mm (1.339 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.189 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 44 mm (1.732 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: 1.12 mm (0.044 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 8xD\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\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 Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Stainless Steel, Steel, Superalloys and Titanium\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: A1247\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 5060590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51749277434162,"sku":"5060590","price":190.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ef4f0455ff845d4d4279233f969cedc_61576255-9618-4869-9e3d-5c1c85c74654.jpg?v=1788903936","url":"https:\/\/voomisupply.com\/products\/walter-titex-5060590-cobalt-jobber-drill-bit-4-8mm","provider":"Voomi Supply","version":"1.0","type":"link"}
