Walter-titex 5060520 Cobalt Jobber Drill Bit 1/2 in

Product Description

The WALTER-TITEX 5060520 is a cobalt jobber-length drill bit designed for high-performance drilling in demanding materials. Built to Series A1247 specifications, this 1/2 inch diameter bit features a 130-degree split point and a parabolic flute geometry that promotes fast chip evacuation and reduces heat buildup. The oxide coating adds surface hardness and lubricity. With an overall length of 5-15/16 inches and a flute length of 3-31/32 inches, it delivers extended reach in blind hole and stack drilling applications. Machinists, tool and die professionals, and industrial maintenance technicians are the primary installers of this bit.

This drill bit is engineered for use in cast iron, non-ferrous metals, stainless steel, carbon steel, superalloys, and titanium. Its parabolic flute design with an 8xD flute-to-diameter ratio supports deep-hole drilling up to a maximum depth of 3.425 inches. The straight-cylindrical shank with a 1/2 inch shank diameter fits standard three-jaw drill chucks and compatible collet holders. Applications include blind hole drilling and stack drilling in production and maintenance environments where hole quality and tool longevity are critical.

Key Features

• Cobalt construction with oxide coating for heat resistance and extended tool life in hard and abrasive materials
• 130-degree split point reduces thrust force and improves self-centering without a pilot hole
• Parabolic flute geometry with web-thinned, tapered web promotes efficient chip evacuation in deep holes
• 8xD flute-to-diameter ratio supports maximum drilling depth of 3.425 inches
• Right-hand cut with straight-cylindrical shank; compatible with standard drill chucks and collet systems
• Meets ANSI, ISO, BS, and DIN standards for dimensional accuracy; tolerance class h8 on shank diameter

Compatibility

Designed for use in drill presses, CNC machining centers, and hand-held drilling equipment that accept a 1/2 inch straight-cylindrical shank. Suitable for drilling cast iron, non-ferrous metal, stainless steel, steel, superalloys, and titanium workpieces.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill chuck or collet is fully tightened and the workpiece is securely fixtured before operation. Do not exceed the recommended maximum drilling depth of 3.425 inches for this bit. Inspect the cutting edges and point geometry before each use and replace the bit if chipping or wear is detected.
