Walter-titex 5060571 Cobalt Jobber Drill Bit 3.4mm

Product Description

The WALTER-TITEX 5060571 is a cobalt jobber length drill bit designed for high-performance drilling in demanding materials. With a 3.4 mm (0.1339 inch) diameter, a 130-degree split point, and an oxide coating, this bit handles cast iron, stainless steel, steel, non-ferrous metals, superalloys, and titanium with consistent accuracy. The parabolic flute geometry improves chip evacuation and reduces heat buildup during extended cutting cycles. An overall length of 2.75 inches and a straight-cylindrical shank make it compatible with standard drill chucks. Licensed trades and production machinists rely on this bit for blind hole drilling and stack drilling operations where point accuracy and flute efficiency are critical.

The 5060571 is suited for use in both blind hole and stack drilling applications across ferrous and non-ferrous workpieces. Its 8xD flute-to-diameter ratio supports deeper cuts relative to bit diameter, making it practical for operations where drill depth matters. The split point reduces walking at entry and lowers thrust requirements, which is especially valuable when working with hard materials like stainless steel, superalloys, and titanium. This bit meets ANSI and ISO standards and carries BS and DIN specification designations, making it appropriate for controlled production environments and job-shop applications alike.

Key Features

• Cobalt construction with oxide coating for heat resistance and extended tool life in hard materials
• 130-degree split point reduces entry walking and lowers feed force requirements
• Parabolic flute design promotes efficient chip evacuation in deep and blind hole applications
• Web-thinned tapered web configuration reduces cutting resistance and improves centering
• 8xD flute-by-diameter ratio supports deeper drilling relative to bit size
• Meets ANSI and ISO standards with BS and DIN specification designations

Compatibility

Designed for use in materials including cast iron, non-ferrous metals, stainless steel, carbon and alloy steel, superalloys, and titanium (workpiece material codes K, M, N, P, and S). Suited for blind hole and stack drilling operations. Straight-cylindrical shank fits standard keyed and keyless drill chucks accepting 0.1339 inch shank diameter. Part of the Walter-Titex Series A1247 high-performance jobber drill line.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified trade professionals familiar with metal cutting operations. Ensure the workpiece is securely clamped and the drill press or machine spindle is properly aligned before beginning. This bit does not support coolant-through delivery, so external coolant or cutting fluid should be applied when drilling stainless steel, superalloys, or titanium to manage heat. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
