Walter-titex 5059371 Jobber Drill Bit No.3 Hss Parabolic

Product Description

The WALTER-TITEX 5059371 is a jobber-length drill bit designed for high-performance metal drilling in professional trade and industrial applications. It carries a No. 3 wire gauge size with a decimal diameter of 0.2130 inches and features a 130-degree split point for precise entry and reduced walking on hard surfaces. The bit is ground from high-speed steel with an oxide coating to resist heat buildup during extended runs. A parabolic flute geometry improves chip evacuation, making it well-suited for blind hole drilling and stack drilling operations where chip packing is a common problem. Right-hand cut with a straight-cylindrical shank for universal chuck compatibility.

This bit is intended for use on cast iron, non-ferrous metals, and steel workpieces in both shop and field environments. It fits standard drill press, hand drill, and CNC drilling setups that accept a straight-cylindrical shank. Typical applications include blind hole production and stack drilling in fabrication, mechanical, and maintenance settings. The Series A1222 designation identifies it within WALTER-TITEX's high-performance jobber drill lineup, built to ANSI and ISO standards with BS and DIN specification designations.

Key Features

• No. 3 wire size — 0.2130 inch decimal diameter with h8 diameter tolerance for consistent fit
• 130-degree standard point angle with web thinning for fast, accurate entry into ferrous and non-ferrous materials
• Parabolic flute design with 8xD flute-to-diameter ratio promotes efficient chip removal in deep or stacked cuts
• Oxide coating reduces friction and extends tool life in high-cycle drilling
• Straight-cylindrical shank fits standard 3-jaw chucks and collet holders without adapters
• Meets ANSI and ISO standards; built to BS and DIN specification designations

Compatibility

Designed for use on cast iron, non-ferrous metal, and steel workpieces. Compatible with any drill press, hand drill, or CNC spindle accepting a straight-cylindrical shank at 0.2130 inch diameter. Suitable for blind hole and stack drilling tool applications.

Installation Notes

Installation and use should be performed by qualified machinists, tool-and-die technicians, or trained maintenance professionals. Secure the shank fully in the chuck and verify runout before drilling. Power down and de-energize all equipment before changing bits. Do not exceed the recommended maximum drilling depth of 1.89 inches without retracting to clear chips, particularly in blind hole operations.
