Walter-titex 5060452 Cobalt Jobber Drill Bit No. 12

Product Description

The WALTER-TITEX 5060452 is a cobalt jobber length drill bit sized to No. 12 wire gauge (0.1890 inches decimal), built for high-performance drilling in demanding materials. It features a 130-degree split point that starts on contact without a center punch, a parabolic flute geometry that evacuates chips aggressively, and an oxide coating that reduces heat and friction at the cutting edge. Overall length is 3-3/8 inches with a flute length of 2-3/64 inches. The straight-cylindrical shank (0.1890 inches diameter) fits standard three-jaw drill chucks. This bit is rated for blind hole and stack drilling applications in production and maintenance environments.

This drill bit is suited for professional drilling in cast iron, non-ferrous metals, stainless steel, carbon and alloy steels, superalloys, and titanium. The parabolic flute at an 8xD flute-to-diameter ratio supports deeper cuts relative to bit diameter, making it a practical choice for metalworking shops, maintenance mechanics, pipefitters, and fabricators who routinely work with hard or abrasive base materials. Maximum drilling depth is 1.7320 inches (44.00 mm). Series A1247 designates it within the WALTER-TITEX high-performance catalog family.

Key Features

• No. 12 wire gauge size — 0.1890 inches decimal diameter with h8 tolerance
• 130-degree split point for self-centering starts and reduced thrust force
• Parabolic flute design promotes fast chip evacuation in deep and stacked cuts
• Cobalt construction with oxide coating for heat and wear resistance in hard metals
• Web-thinned, tapered web configuration reduces cutting resistance at the chisel edge
• Right-hand cut, straight-cylindrical shank — fits standard drill chucks without adapters
• Meets ANSI, ISO, BS, and DIN standards

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, steel, superalloys, and titanium workpieces. Suitable for blind hole and stack drilling operations. Workpiece material codes K, M, N, P, and S per ISO classification.

Installation Notes

This bit is installed and operated by machinists, maintenance mechanics, and metalworking tradespeople using standard drill presses, magnetic drills, or hand-held drill motors with a three-jaw chuck. Secure the workpiece firmly before drilling to prevent rotation. Use appropriate cutting fluid or coolant on stainless steel, superalloys, and titanium to extend tool life, even though this bit does not have internal coolant-through capability. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
