Walter-titex 5062611 Extra Length Drill Bit 0.2559 in Hss

Product Description

The WALTER-TITEX 5062611 is an extra length high speed steel (HSS) twist drill bit designed for deep-hole drilling applications in metalworking environments. Built to DIN 1869-I and ANSI standards, this Series A1622 bit measures 0.2559 inches (6.50 mm) in diameter with a parabolic flute geometry and a 130-degree split point for improved chip evacuation and reduced thrust in difficult materials. The M2 HSS construction and web-thinned, tapered web configuration make it suitable for high-performance drilling in production and maintenance settings. Licensed machinists, tool-and-die technicians, and metalworking professionals install this bit on standard drill presses, CNC machining centers, and hand-held power tools.

This bit is engineered for blind hole and stack drilling applications. Primary workpiece materials include cast iron, non-ferrous metals, and steel. Secondary materials include cobalt alloys, iron, nickel, and titanium alloys. With a flute-by-diameter ratio of 16xD and a maximum drilling depth of 5.4720 inches (139.00 mm), it handles extended-reach drilling tasks that standard-length bits cannot reach. The uncoated finish keeps regrinding straightforward in high-volume shop environments.

Key Features

• Parabolic flute geometry promotes efficient chip evacuation in deep-hole operations
• 130-degree drill point angle reduces thrust and improves centering on entry
• Web-thinned tapered web lowers cutting resistance across cast iron, steel, and non-ferrous metals
• M2 high speed steel construction rated for high-performance drilling grades
• Right-hand cutting direction; compatible with standard drill chucks and collet holders
• Meets ANSI, DIN 1869-I, and ISO standards for dimensional consistency

Compatibility

Designed as an OEM-style replacement and standard production drill bit for metalworking operations requiring extended reach; suitable for use in drill presses, CNC machining centers, and power hand tools accepting a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with cutting tool safety practices. Ensure the workpiece is securely clamped and the machine spindle is fully stopped before changing or inspecting the bit. Use appropriate cutting fluid or coolant for the workpiece material where permitted, noting this bit does not feature through-coolant capability. Follow machine manufacturer RPM and feed rate recommendations for the workpiece material and bit diameter to prevent premature wear or breakage.
