Walter-titex 5057237 Screw Machine Drill Bit 0.3189 in

Product Description

The WALTER-TITEX 5057237 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from cobalt and vanadium high speed steel with a bright, uncoated finish, this bit delivers the toughness and heat resistance required when cutting through hard and abrasive materials. It features a 0.3189-inch diameter, a 130-degree split point, and a parabolic flute geometry that improves chip evacuation and reduces the need for frequent tool retraction. The straight-cylindrical shank seats securely in standard drill chucks. Machinists and tool-room technicians working in fabrication, manufacturing, and maintenance environments rely on this series for consistent, accurate hole quality.

This drill bit is suited for screw machine operations and general-purpose drilling where a stub-length tool is preferred for rigidity and reduced runout. It performs across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals, making it a versatile choice on the shop floor. The Series A1148 designation places it within a line built to DIN and ISO standards, ensuring dimensional consistency for production and maintenance work alike. Typical users include machinists, tool-and-die makers, and maintenance mechanics.

Key Features

• Cobalt and vanadium high speed steel construction for elevated heat and wear resistance
• 130-degree split point reduces thrust and improves self-centering on hard materials
• Parabolic flute profile promotes efficient chip evacuation at higher feed rates
• Web-thinned, tapered web configuration reduces cutting resistance
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• Meets DIN, ISO, and BS specification designations for dimensional accuracy

Compatibility

Designed as an OEM-style screw machine length drill bit compatible with workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel. Fits standard drill chucks and collets accepting a straight-cylindrical shank in the 0.3000-inch to 0.3500-inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance mechanics familiar with machine tool operation. Ensure the drill press, lathe, or CNC machine is fully powered down and locked out before changing tooling. Verify chuck or collet runout is within acceptable tolerance before drilling to maintain the tight diameter tolerance of this bit. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and spindle speed selection.
