Walter-titex 5057160 Cobalt Screw Machine Drill Bit

Product Description

The WALTER-TITEX 5057160 is a cobalt vanadium high-speed steel screw machine length drill bit designed for high-performance drilling in demanding materials. It has a 0.0827 inch (2.10 mm) diameter, a 130-degree split point for accurate starts, and a parabolic flute profile that promotes efficient chip evacuation. The straight cylindrical shank measures 0.0830 inch in diameter. At 1.5 inches overall length, this stub-length bit delivers rigidity in tight-clearance setups. It is intended for use by machinists, toolroom technicians, and production drilling operators working on metal fabrication or precision machining applications.

This drill bit is suited for drilling cast iron, hardened materials, non-ferrous metals, stainless steel, and carbon steel. The screw machine length format makes it a common choice for drill press, CNC machining center, and turret lathe applications where short overhang reduces deflection and improves hole accuracy. The 3xD flute-to-diameter ratio and web-thinned tapered web design support clean entry and consistent hole geometry across production runs.

Key Features

• Cobalt vanadium HSS construction for heat and wear resistance in hard and abrasive materials
• 130-degree split point reduces thrust and improves self-centering on entry
• Parabolic flute geometry promotes fast chip evacuation and reduced recutting
• Web-thinned tapered web lowers cutting resistance at the chisel edge
• Screw machine (stub) length provides added rigidity and reduced deflection
• Meets DIN, ISO, and BS specification designations for dimensional consistency

Compatibility

Designed as a screw machine length replacement or production drill bit for use in standard straight-shank drill chucks and collets accepting a 0.0830 inch shank diameter, consistent with Series A1148 tooling.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with rotating cutting tool setup. Secure the shank fully in the chuck or collet and verify concentricity before drilling. Always power down and de-energize the machine spindle before changing tooling. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection based on workpiece material.
