Walter-titex 5059478 Jobber Drill Bit 3/32 Inch Hss

Product Description

The WALTER-TITEX 5059478 is a jobber length drill bit designed for high-performance drilling in cast iron, non-ferrous metals, and steel. Manufactured from high speed steel with an oxide coating, it measures 3/32 inch (0.0938 inch decimal) in diameter with an overall length of 2-1/4 inches. The parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup during extended cutting cycles. The 130-degree drill point angle and web-thinned tip improve penetration and reduce thrust force, making this bit suitable for precision work in blind holes and stack drilling applications. Licensed machinists and maintenance mechanics are the typical users.

This drill bit is built for blind hole drilling and stack drilling operations in industrial and trade settings. The straight-cylindrical shank seats securely in standard three-jaw chucks and collet-style tool holders. Primary workpiece materials include cast iron, non-ferrous metals, and steel, making it a versatile tool for HVAC fabrication shops, mechanical contractors, and maintenance facilities that drill structural and sheet components. The parabolic flute design supports deeper cuts relative to diameter, with a flute-by-diameter ratio of 8xD and a maximum drilling depth of approximately 1.024 inches.

Key Features

• Rated for cast iron, non-ferrous metal, and steel workpieces
• Meets ANSI and ISO standards with BS and DIN specification designations

Compatibility

Designed for use in standard drill chucks and collet holders accepting a 3/32 inch straight-cylindrical shank. Suitable for blind hole and stack drilling operations on cast iron, non-ferrous metal, and steel. Part of the WALTER-TITEX Series A1222, covering the 0.0500 to 0.1000 inch decimal diameter range.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or maintenance mechanic familiar with proper tool holding and drilling procedures. Ensure the drill chuck or collet is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Disconnect power to the drill press or deactivate CNC equipment before changing tooling. Avoid exceeding the rated maximum drilling depth of 1.024 inches to prevent tool deflection or breakage.
