Walter-titex 5062532 Extra Length Drill Bit Wire 4 Hss

Product Description

The WALTER-TITEX 5062532 is a wire gauge size 4 (0.2090 inches) extra length drill bit designed for deep-hole drilling in production and job shop environments. Built from M2 high-speed steel with a bright uncoated finish, it features a parabolic flute geometry and a 130-degree split point with web thinning for fast chip evacuation and reduced thrust in difficult materials. The straight-cylindrical shank measures 0.2090 inches in diameter with a shank length of approximately 2.559 inches. Overall length is 8-1/16 inches and flute length is 5-1/2 inches, giving it the reach needed for deep blind-hole applications where standard-length bits fall short. Licensed machinists, toolroom technicians, and production drilling operators are the primary users.

This bit is suited for blind hole drilling and stack drilling operations across a range of workpiece materials. Primary materials include cast iron, non-ferrous metals, and steel. Secondary materials include cobalt, iron, nickel, and titanium alloys. The parabolic flute profile and web-thinned point help maintain chip flow and reduce heat buildup when drilling to maximum depths approaching 5.157 inches. The bit carries a flute-to-diameter ratio of 16xD, making it appropriate for applications where standard extra-length bits cannot achieve required depth without repositioning.

Key Features

• Wire size 4 (0.2090 inches) diameter with matched straight-cylindrical shank
• M2 high-speed steel construction with bright uncoated finish for general-purpose drilling
• Parabolic flute design promotes efficient chip evacuation at depth
• 130-degree point angle with web thinning and UFL point type reduces entry thrust
• 16xD flute-to-diameter ratio supports deep blind hole and stack drilling
• Conforms to ANSI, DIN 1869-I, and ISO standards

Compatibility

The 5062532 belongs to WALTER-TITEX Series A1622 and is designed for use in standard drill chucks and collet holders accepting a 0.2090-inch straight shank. Rated for cast iron, non-ferrous metal, steel, cobalt, iron, nickel, and titanium alloy workpieces per the manufacturer material codes K, N, P, M, O, and S.

Installation Notes

This drill bit is installed by toolroom machinists and CNC setup technicians in drilling machines, machining centers, or drill presses equipped with an appropriate chuck or collet. Secure the shank fully within the holding device before operation and confirm runout is within acceptable limits for the application. Power down and lock out the machine before changing tooling. Do not exceed the recommended maximum drilling depth of 5.157 inches without confirming chip clearance, as parabolic flutes still require periodic pecking cycles at full depth to prevent packing.
