Walter-titex 5062518 Extra Length Drill Bit 0.144 in Hss

Product Description

The WALTER-TITEX 5062518 is an extra length, high speed steel (HSS M2) twist drill bit designed for deep-hole and extended-reach drilling applications in metal fabrication and machining environments. Built to Series A1622, it measures 0.144 inches in diameter with an overall length of 6.5 inches and a parabolic flute length of approximately 4.53 inches. The 130-degree drill point angle and web-thinned tip geometry reduce entry force and improve chip clearance. This bit is intended for use by machinists, tool-and-die professionals, and industrial maintenance technicians working with precision metal components.

This drill bit is suited for blind hole drilling and stack drilling operations. Primary workpiece materials include cast iron, non-ferrous metals, and steel. It also handles secondary materials such as cobalt alloys, iron, nickel, and titanium alloys. The straight-cylindrical shank seats securely in standard drill chucks and collet systems. Its 16xD flute-to-diameter ratio and parabolic flute geometry support efficient chip evacuation in deep-hole passes, making it a practical choice for production runs or precision repair work where standard-length bits cannot reach.

Key Features

• Wire size 27 (0.144 inches) diameter with straight-cylindrical shank for standard chuck compatibility
• M2 high speed steel construction, uncoated, for use across cast iron, steel, and non-ferrous metals
• 130-degree drill point angle with UFL point type and web-thinned, tapered web for reduced thrust
• Parabolic flute design promotes chip evacuation in deep blind-hole and stack drilling scenarios
• Extra length body at 6.5 inches overall supports extended-reach applications where standard bits fall short
• Meets ANSI, DIN 1869-I, and ISO standards for dimensional and performance compliance

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 0.144-inch straight-cylindrical shank. Rated for primary workpiece materials cast iron, non-ferrous metal, and steel, with secondary material suitability for cobalt alloys, iron, nickel, and titanium alloys per Series A1622 specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with drilling feeds, speeds, and workholding practices for HSS tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable tolerance to protect the small-diameter tip. Power down all equipment before changing tooling. Do not exceed the maximum drilling depth of approximately 4.29 inches in a single operation without retracting to clear chips.
