Walter-titex 5058611 Jobber Length Drill Bit 13.2 Mm Hss

Product Description

The WALTER-TITEX 5058611 is a jobber length twist drill bit designed for general-purpose and high-performance drilling in steel and cast iron. The bit measures 13.2 mm (0.5197 inches) in diameter with an overall length of 151 mm (5-15/16 inches) and a flute length of 101 mm (3-31/32 inches). Manufactured from high speed steel with an oxide finish coating, it features a 118-degree standard drill point, a tapered web with web thinning, and a two-flute regular spiral configuration. The straight-cylindrical shank matches the drill diameter at 0.5197 inches, making it compatible with standard drill chucks used in machine shop and field operations.

This drill bit is suited for blind hole drilling and stack drilling applications in residential, commercial, and industrial settings. Primary workpiece materials include steel and cast iron, making it a practical choice for HVAC, plumbing, electrical, and general metalworking trades. The Series A1211 designation places it within a well-documented family of jobber drills built to ANSI, ISO, DIN, and BS specifications. Right-hand cut spiral flutes efficiently evacuate chips during through and blind hole operations, reducing heat buildup and extending tool life in moderate to heavy drilling cycles.

Key Features

• 13.2 mm (0.5197 inch) diameter with h8 diameter tolerance for precise fit in drilled holes
• 118-degree standard drill point with web thinning for reduced entry force and improved centering
• High speed steel construction with oxide coating for corrosion resistance and lubricity
• Two-flute regular spiral design supports efficient chip evacuation in steel and cast iron
• Rated for blind hole and stack drilling applications per Series A1211 design parameters
• Meets ANSI, ISO, DIN, and BS standards for dimensional accuracy and tool geometry

Compatibility

Designed as a general-purpose OEM-style jobber drill for use in standard drill chucks and drill press or CNC applications targeting steel and cast iron workpieces. Primary workpiece material codes P and K indicate suitability for general steels and cast irons per ISO material classification.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and trade professionals using drill presses, hand drills, or CNC equipment. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before operation. Do not exceed the maximum drilling depth of 87 mm (3.425 inches) as specified for this geometry. Use appropriate cutting fluid or coolant for extended drilling cycles in ferrous materials to preserve edge life, noting that this bit does not support through-spindle coolant delivery.
