Walter-titex 5057219 Screw Machine Drill Bit 0.2598 in

Product Description

The WALTER-TITEX 5057219 is a screw machine length drill bit engineered for high-performance drilling in demanding trade and industrial applications. Built from Cobalt Vanadium High Speed Steel, this two-flute bit features a parabolic flute geometry and a 130-degree split point that reduces walking and improves chip evacuation. The straight-cylindrical shank measures 0.2598 inches in diameter and fits standard drill chucks without modification. With a web-thinned, tapered web configuration and an overall length of 2.75 inches, this bit is designed for use in machine tool operations where rigidity and accuracy are critical. It is rated for universal tool performance across a range of workpiece materials and meets DIN, ISO, and BS standards.

The 5057219 is suited for screw machine, CNC, and bench drill press applications in manufacturing, fabrication, and mechanical service environments. It handles cast iron, stainless steel, hardened materials, non-ferrous metals, and general steel stock. The parabolic flute design at a 3xD flute-to-diameter ratio promotes efficient chip clearing at depth, reducing heat buildup and bit deflection. Licensed machinists, tool-and-die tradespeople, and mechanical contractors working in tight-tolerance environments will find this bit appropriate for repetitive production drilling where consistent hole quality is required.

Key Features

• 0.2598-inch diameter with a tight tolerance of -0.00087 to 0.000 inches for precise hole sizing
• 130-degree split point reduces drill walking and lowers thrust force at entry
• Parabolic flute geometry improves chip evacuation and reduces heat at the cutting zone
• Cobalt Vanadium HSS construction supports drilling in stainless steel and hard materials
• Web-thinned tapered web increases cutting efficiency and extends bit service life
• Meets DIN, ISO, and BS standards — Series A1148, High Performance grade

Compatibility

Designed as an OEM-grade screw machine length drill bit for use in standard straight-shank drill chucks on screw machines, CNC machining centers, and bench drill presses. Rated for primary workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel per Series A1148 specifications.

Installation Notes

Installation and use should be performed by qualified machinists or mechanical tradespeople familiar with rotating tool safety practices. Ensure the drill chuck is properly tightened and the workpiece is securely fixtured before operation. Power down all equipment before changing bits or inspecting the cutting edge. Do not exceed the maximum drilling depth of 0.800 inches without retracting to clear chips.
