Walter-titex 5060597 Cobalt Jobber Drill Bit 5.5 Mm

Product Description

The WALTER-TITEX 5060597 is a cobalt jobber-length drill bit designed for high-performance drilling in tough materials including stainless steel, cast iron, superalloys, and titanium. It measures 5.5 mm in diameter with an overall length of 93 mm and a flute length of 57 mm. The 130-degree split point reduces walking and breakthrough burring, while the oxide coating improves lubricity and wear resistance. The parabolic flute geometry promotes efficient chip evacuation, making this bit well-suited for production environments where tool life and hole quality matter. It belongs to the WALTER-TITEX Series A1247 and conforms to ANSI, ISO, BS, and DIN standards.

This bit is built for drilling blind holes and stack drilling applications in ferrous and non-ferrous metals. The straight-cylindrical shank fits standard drill chucks without adapters. With an 8xD flute-to-diameter ratio and a maximum drilling depth of 48 mm, it handles moderate-depth holes without coolant-through capability. Typical users include machinists, tool-and-die shops, and maintenance trades working in aerospace, metal fabrication, and industrial maintenance settings where cobalt tooling is specified over standard high-speed steel.

Key Features

• Cobalt construction with oxide coating for improved wear resistance in hard and abrasive materials
• 130-degree split point reduces entry force and minimizes drill walk on curved or interrupted surfaces
• Parabolic flute design promotes fast chip evacuation in deep and blind hole drilling
• Web-thinned, tapered web configuration reduces thrust load at the cutting edge
• Straight-cylindrical shank in h8 tolerance for accurate, secure chuck seating
• Rated for blind hole and stack drilling applications per Series A1247 specification

Compatibility

Designed as a jobber-length OEM-style replacement or direct-use drill bit compatible with standard drill chucks accepting a 0.2165-inch straight shank. Rated for primary workpiece materials including cast iron, non-ferrous metals, stainless steel, carbon and alloy steel, superalloys, and titanium per material codes K, M, N, P, and S.

Installation Notes

Installation is performed by machinists or maintenance trades using standard drill press, CNC, or hand-held power equipment. Secure the straight shank firmly in the chuck before operation and verify runout within acceptable limits for the tolerance class. No coolant-through capability is present on this bit, so external cutting fluid or air blast is recommended when drilling stainless steel, titanium, or superalloys to manage heat buildup. Follow applicable shop safety procedures and machine guarding requirements during use.
