Walter-titex 5059407 Jobber Drill Bit Wire 8 Hss Oxide

Product Description

The WALTER-TITEX 5059407 is a jobber length drill bit designed for high-performance drilling in ferrous and non-ferrous materials. Built from high speed steel with an oxide coating, it measures 3-3/8 inches in overall length and carries a wire size designation of 8, corresponding to a decimal diameter of 0.1990 inches. The 130-degree split point with web thinning reduces thrust force and improves self-centering at entry. The parabolic flute geometry promotes efficient chip evacuation, making this bit well suited for production drilling and situations where chip management is critical. Licensed HVAC, plumbing, and mechanical contractors, as well as machining and fabrication professionals, will find this bit appropriate for both blind hole and stack drilling operations.

This drill bit is rated for primary workpiece materials including cast iron, non-ferrous metals, and steel. The Series A1222 designation places it within a defined performance tier under ANSI and ISO standards, as well as BS and DIN specification designations. The straight-cylindrical shank with a diameter of 0.1990 inches fits standard drill chucks without adapters. It is appropriate for use in drill presses, CNC machining centers, and hand-held power drills where the operator can maintain proper feed rate and alignment. The 8xD flute-to-diameter ratio supports deeper penetration relative to bit diameter while maintaining chip clearance.

Key Features

• Wire size 8 decimal diameter of 0.1990 inches with h8 tolerance for consistent fit
• 130-degree drill point angle with web thinning for reduced entry thrust and accurate self-starting
• Parabolic flute geometry for aggressive chip evacuation in blind hole and stack drilling
• Oxide coating on high speed steel substrate provides surface hardness and lubricity
• Straight-cylindrical shank compatible with standard chuck systems
• Meets ANSI, ISO, BS, and DIN specification requirements

Compatibility

Designed for drilling cast iron, non-ferrous metals, and steel workpieces. Suitable for blind hole and stack drilling applications as noted in the Series A1222 product specifications.

Installation Notes

Installation of this drill bit should be performed by qualified machinists, tool and die technicians, or experienced trade professionals. Secure the straight-cylindrical shank firmly in a properly rated drill chuck before operation and verify concentricity to prevent runout. Always power down and lock out the drilling equipment before changing bits. Do not exceed the recommended feed rate or drilling depth of 1.732 inches for the workpiece material in use.
