Walter-titex 5057189 Screw Machine Drill Bit 31/64 in

Product Description

The WALTER-TITEX 5057189 is a screw machine length drill bit designed for high-performance drilling in demanding materials. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit measures 31/64 inch (0.4844 inches) in diameter with an overall length of 4-1/32 inches. The 130-degree split point and web-thinned, tapered web construction reduce thrust and improve centering on entry. A parabolic flute design promotes efficient chip evacuation, making this bit well-suited for interrupted cuts and deep-hole work. It is part of the Series A1148 and carries a High Performance grade designation, meeting DIN, ISO, and BS standards. Installation and operation are handled by machinists, tooling technicians, and industrial maintenance professionals.

This drill bit is rated for use on cast iron, hard materials, non-ferrous metals, stainless steel, and general steel. The screw machine length format provides a shorter, stiffer profile compared to jobber-length bits, reducing deflection in production drilling and CNC applications. With a 3xD flute-to-diameter ratio and a maximum drilling depth of 1.5000 inches, it fits standard production drilling setups where rigidity and chip control matter. The straight-cylindrical shank seats securely in drill chucks and collet holders. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat resistance in hard and stainless workpieces
• 130-degree split point with web thinning reduces entry thrust and improves self-centering
• Parabolic flute geometry accelerates chip removal and reduces re-cutting
• Screw machine length (4-1/32 inches overall) delivers extra rigidity versus jobber-length bits
• Maximum drilling depth of 1.5000 inches with a 3xD flute-to-diameter ratio
• Meets DIN, ISO, and BS standards; Universal tool performance classification

Compatibility

Designed as an OEM-style replacement or direct tooling selection for production drilling operations involving cast iron, hard materials, non-ferrous metals, stainless steel, and steel workpieces. Compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank at 0.4844 inches diameter.

Installation Notes

This bit is installed and operated by machinists and tooling technicians using standard drill presses, CNC machining centers, or hand-held industrial drills. Secure the straight-cylindrical shank fully in the chuck or collet before running the spindle. Ensure the machine is powered off and fully stopped before changing or inspecting the bit. Do not exceed the rated maximum drilling depth of 1.5000 inches in a single pass without appropriate pecking cycles to clear chips and reduce heat buildup.
