Walter-titex 5060570 Cobalt Jobber Drill Bit 3.3 Mm

Product Description

The WALTER-TITEX 5060570 is a cobalt jobber length drill bit engineered for high-performance drilling in demanding materials. Built to Series A1247 specs, it measures 3.3 mm (0.1299 inches) in diameter with a 2-9/16 inch overall length and features a 130-degree split point for positive engagement and reduced walking on entry. The parabolic flute design improves chip evacuation, making it effective in deeper cuts up to 30 mm. An oxide coating adds surface hardness and heat resistance. This bit is suited for licensed machinists, maintenance technicians, and trade professionals working with ferrous and non-ferrous metals.

This drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, carbon steel, superalloys, and titanium. It is designed for blind hole applications and stack drilling operations where consistent chip removal and point stability are critical. With a straight-cylindrical shank at 0.1299 inches diameter and a flute-to-diameter ratio of 8xD, it fits standard drill chucks and is appropriate for CNC drilling centers, drill presses, and hand-held power tools used in production and field service environments.

Key Features

• Cobalt construction with oxide coating for heat and wear resistance in hard materials
• 130-degree split point reduces entry force and prevents bit walking
• Parabolic flute geometry promotes efficient chip evacuation in deep holes
• 8xD flute-to-diameter ratio supports drilling depths up to 30 mm (1.181 inches)
• Web-thinned, tapered web configuration lowers thrust requirements
• Meets ANSI, ISO, BS, and DIN standards for consistent dimensional tolerance (h8)

Compatibility

Rated for primary workpiece materials including cast iron, non-ferrous metals, stainless steel, steel, superalloys, and titanium (material codes K, M, N, P, S). Suited for blind hole and stack drilling tool applications. Straight-cylindrical shank fits standard drill chucks accepting 0.1299-inch shank diameters.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Secure the workpiece fully before drilling to prevent movement during stack or blind hole operations. Verify chuck compatibility with the 0.1299-inch straight-cylindrical shank before use. Coolant-through is not supported on this bit; use external cutting fluid when drilling stainless steel, superalloys, or titanium to manage heat buildup.
