Walter-titex 5062553 Extra Length Drill Bit 0.2656 in Hss

Product Description

The WALTER-TITEX 5062553 is a high-performance extra length drill bit designed for deep-hole and extended-reach drilling applications in metalworking and industrial environments. The bit measures 0.2656 inches in diameter with an overall length of 8.84 inches (8-27/32 inches) and a flute length of 6.09 inches (6-3/32 inches), providing a 16xD flute-to-diameter ratio suited for drilling well beyond standard depth. Constructed from uncoated high speed steel with a parabolic flute design and web-thinned tapered web, it handles demanding cutting tasks across a range of workpiece materials. Licensed tradespeople and machining specialists install this bit using standard drill presses, CNC machining centers, or hand-held drilling equipment.

This bit is built for blind hole and stack drilling operations in cast iron, non-ferrous metals, and steel, as well as secondary materials including cobalt, iron, nickel, and titanium alloys. The Series A1622 designation places it within a standardized extra length product line conforming to ANSI, DIN 1869-I, and ISO specifications. It suits production and maintenance environments where standard-length bits cannot reach the required depth. The straight-cylindrical shank with a shank diameter of 0.2660 inches provides secure tool holding in collet chucks and drill chucks.

Key Features

• Parabolic flute geometry improves chip evacuation in deep-hole drilling
• Web-thinned tapered web reduces thrust and entry resistance
• Maximum drilling depth of 5.63 inches (143.00 mm) for extended-reach applications
• Right-hand cutting direction with a 130-degree drill point angle for standard and cast materials
• Uncoated high speed steel construction — no coating delamination risk in abrasive workpiece materials
• Conforms to ANSI, DIN 1869-I, and ISO standards for dimensional consistency

Compatibility

Rated for primary workpiece materials including cast iron (K), non-ferrous metal (N), and steel (P), and secondary materials including cobalt, iron, nickel, and titanium alloy (M, O, S material codes). Designed as an OEM-grade replacement or direct selection for applications requiring a Series A1622 extra length drill in the 0.2656-inch diameter class.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotating cutting tools. Secure the straight-cylindrical shank firmly in a compatible collet or drill chuck before operation, and verify runout before beginning the cut. Power down and de-energize all equipment before changing or inspecting the bit. Follow shop-specific feeds and speeds guidelines for the workpiece material grade — do not exceed the rated maximum drilling depth of 5.63 inches without confirming rigidity of the setup.
