Walter-titex 5060458 Cobalt Jobber Drill Bit No. 18

Product Description

The WALTER-TITEX 5060458 is a cobalt jobber length drill bit sized at No. 18 (0.1695 inches decimal), designed for high-performance drilling in demanding materials. It features a 130-degree split point, parabolic flute geometry, and an oxide coating that helps extend tool life under heat and friction. The overall length is 3-5/32 inches, with a flute length of 1-27/32 inches and a straight-cylindrical shank. The web-thinned, tapered web design reduces thrust force on entry. This bit suits metalworking professionals who need reliable penetration in tough ferrous and non-ferrous substrates.

This drill bit is rated for use in cast iron, non-ferrous metals, stainless steel, carbon and alloy steels, superalloys, and titanium. It is built for blind hole drilling and stack drilling applications where consistent hole quality and chip evacuation matter. The parabolic flute profile improves chip flow, making it appropriate for production environments and job shop use alike. Meets ANSI and ISO standards, with specification designations including BS and DIN. Sold individually; minimum order quantity is 10 units.

Key Features

• No. 18 wire size, 0.1695-inch decimal diameter with h8 diameter tolerance for precise fitment
• 130-degree split point reduces walking and lowers required thrust on entry
• Parabolic flute geometry promotes aggressive chip evacuation in deep and stack drilling
• Cobalt construction with oxide coating improves heat resistance and extends tool life
• Web-thinned, tapered web reduces cutting resistance without sacrificing core strength
• 8xD flute-to-diameter ratio supports drilling to a maximum depth of 1.535 inches (39.00 mm)

Compatibility

Designed for use in cast iron, non-ferrous metals, stainless steel, steel, superalloys, and titanium workpieces, corresponding to material codes K, M, N, P, and S. Suitable for blind hole and stack drilling operations in machining and fabrication environments.

Installation Notes

This bit is intended for installation and use by machinists and metalworking trade professionals operating drill presses, CNC machines, or hand-held power drills. Secure the shank fully in the chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Coolant through is not supported on this bit; use external cutting fluid where required by the workpiece material. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
