It measures 7.7 mm (0.3031 inches) in diameter with an overall length of 4-19\/32 inches and a flute length of 2-15\/16 inches. The bit features an oxide coating over its cobalt substrate, a 130-degree split point, and a parabolic flute geometry that promotes efficient chip evacuation. The straight-cylindrical shank is sized at 0.3031 inches in diameter. This drill is intended for use by machinists, maintenance technicians, and trade professionals who require consistent performance in tough ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is engineered for blind hole and stack drilling operations. It performs across a range of primary workpiece materials including cast iron, non-ferrous metal, stainless steel, carbon and alloy steel, and superalloys including titanium. The 8xD flute-to-diameter ratio supports deeper cuts relative to diameter, making it suited for production and maintenance drilling where hole depth and chip control are critical. The parabolic flute design reduces cutting resistance and heat buildup during extended drilling cycles. It conforms to ANSI and ISO standards and carries BS and DIN specification designations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7.7 mm (0.3031 inch) diameter with h8 diameter tolerance for consistent fit and finish\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces thrust force and self-centers on entry\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eOxide-coated cobalt construction improves heat and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration lowers cutting forces\u003c\/li\u003e\n  \u003cli\u003eRated for blind hole and stack drilling applications per Series A1247 design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for drilling cast iron, non-ferrous metals, stainless steel, carbon and alloy steel, and superalloys including titanium.

Secure the workpiece before drilling and verify chuck grip on the straight shank before engaging the spindle. Do not exceed the maximum drilling depth of 2.441 inches (62.00 mm) without retracting to clear chips, particularly in blind-hole applications. Follow applicable shop safety protocols and equipment manufacturer guidelines for speed and feed selection based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.7 mm (0.3031 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: 0.3031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.653 inches (42.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.441 inches (62.00 mm)\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: 0.0707 inches (1.80 mm)\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\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\u003eDrill Bit Material\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\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: A1247\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\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling\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\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: 5060622\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51733802025266,"sku":"5060622","price":419.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ef4f0455ff845d4d4279233f969cedc_419dee5e-7a27-4905-83e5-77eb50a9be27.jpg?v=1788759335","url":"https:\/\/voomisupply.com\/products\/walter-titex-5060622-cobalt-jobber-drill-bit-7-7-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
