Walter-titex 5058293 Jobber Drill Bit No. 12 Hss

Product Description

The WALTER-TITEX 5058293 is a jobber-length twist drill bit designed for general-purpose metal drilling in production and maintenance environments. Manufactured from high speed steel with an oxide coating, this bit carries a 118-degree standard point angle and a 2-flute spiral flute geometry with a tapered, web-thinned web configuration. The straight-cylindrical shank measures 0.1890 inches in diameter, matching the No. 12 wire gauge diameter of 0.1890 inches. Overall length is 3.375 inches with a flute length of 2.0625 inches. The Series A1211 designation indicates a regular spiral, high-performance ground geometry built to ANSI and ISO standards.

This drill bit is suited for right-hand, blind-hole and stack drilling operations in cast iron and steel workpieces. The 8xD flute-to-diameter ratio and web-thinned point reduce thrust and improve chip evacuation in moderate-depth holes up to 1.732 inches. Typical applications include machine shop production drilling, MRO maintenance drilling, and fabrication work where a standard jobber-length bit fits the required depth. The oxide finish provides light corrosion resistance and reduces galling against ferrous materials during dry or light-lubricant drilling.

Key Features

• No. 12 wire gauge size at 0.1890 inches diameter, ground to h8 tolerance for consistent fit in drill chucks and bushings
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• High speed steel construction with oxide coating for light corrosion resistance on ferrous materials
• 2-flute regular spiral geometry supports efficient chip evacuation in blind-hole and stack-drilling applications
• Rated for cast iron and steel workpieces; coolant-through not available on this model
• Manufactured to ANSI and ISO standards; specification designation BS and DIN

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with standard 3-jaw drill chucks, drill presses, CNC machining centers, and hand drills accepting straight-cylindrical shanks at 0.1890 inches diameter. Suitable for use in cast iron and steel workpieces as stated by the manufacturer.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drilling operations and applicable shop safety standards. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits. For blind-hole applications, set depth stops to avoid exceeding the maximum drilling depth of 1.732 inches. Do not exceed the recommended cutting parameters for high speed steel tooling in the workpiece material being drilled.
