Walter-titex 5058339 Jobber Drill Bit Wire 54 Hss Oxide

Product Description

The WALTER-TITEX 5058339 is a jobber-length drill bit sized to wire gauge 54, equivalent to 0.0550 inches in diameter, designed for precision drilling in metalworking applications. Manufactured from high speed steel with an oxide coating for improved wear resistance, this bit features a standard 118-degree split point and a regular spiral flute geometry with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank measures 0.0550 inches in diameter, and the overall length is 1-9/16 inches. With a flute-to-diameter ratio of 8xD and a maximum drilling depth of 0.5910 inches, it is suited to high-performance general-purpose drilling in production or maintenance environments. Licensed machinists, tool and die technicians, and HVAC or mechanical contractors regularly rely on this size for small-diameter through and blind hole work.

This drill bit is rated for use in cast iron and steel workpiece materials. Its two-flute spiral design handles blind hole drilling and stack drilling efficiently, making it a practical choice for sheet metal fabrication shops, HVAC panel drilling, and general mechanical assembly. The bit meets ANSI and ISO standards and carries BS and DIN specification designations, confirming dimensional consistency across production runs. The Series A1211 designation places it within a standardized jobber-length product family suitable for use in standard drill chucks and CNC setups with collets sized to the straight-cylindrical shank diameter.

Compatibility

Designed as an OEM-style jobber-length drill bit for use in cast iron and steel workpieces, compatible with standard drill chucks and collet systems accepting a 0.0550-inch straight-cylindrical shank. Listed under Series A1211.

Installation Notes

This bit is installed and operated by machinists, tool and die technicians, or mechanical tradespeople using standard or CNC drill presses, hand drills, and milling machine setups. Secure the shank fully in the chuck or collet before operation and verify runout before drilling into finished workpieces. Use appropriate cutting fluid or coolant for extended runs in steel to manage heat buildup, noting this bit does not support coolant-through delivery. Inspect the cutting edges and point for wear or chipping before each use, as small-diameter bits are susceptible to breakage under side load or misalignment.
