Walter-titex 5057089 Screw Machine Drill Bit 0.082in Cobalt

Product Description

The WALTER-TITEX 5057089 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from cobalt vanadium high speed steel with a bright uncoated finish, this bit delivers the heat and wear resistance required when cutting hard metals. The 130-degree split point reduces walking and lowers entry force, while the parabolic flute geometry promotes efficient chip evacuation. At 0.082 inches (wire size 45) in diameter with a 1.5-inch overall length, this is a compact, stub-length tool suited for close-quarters drilling where standard length bits create clearance problems.

This drill bit is specified for production and maintenance environments where hole quality and tool life in tough materials are priorities. Primary workpiece materials include steel, stainless steel, cast iron, hard material, and non-ferrous metals. The straight-cylindrical shank seats in standard drill chucks and quick-change systems without modification. The screw machine length body keeps deflection low in short-reach setups, making it a practical choice for machine shops, maintenance technicians, and trade professionals drilling structural or pipe components. Minimum order quantity is 10 units.

Key Features

• Cobalt vanadium high speed steel construction for elevated heat resistance in hard and stainless materials
• 130-degree split point reduces thrust and prevents bit walking on entry
• Parabolic flute with web thinning and tapered web configuration for fast chip removal and reduced cutting resistance
• Screw machine (stub) length of 1.5 inches overall limits deflection in tight drilling applications
• Right-hand cut with straight-cylindrical shank for compatibility with standard drill chucks
• Meets DIN, ISO, and BS standards; rated as high performance universal grade

Compatibility

Designed for use in straight-shank drill chucks and quick-change drilling systems. Suitable for drilling steel, stainless steel, cast iron, hard materials, and non-ferrous metals per Series A1148 specification.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with metalworking operations. Ensure the spindle is fully stopped and the machine is de-energized before changing tooling. Verify chuck runout is within acceptable limits before high-tolerance drilling; excessive runout accelerates wear on small-diameter bits. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
