Walter-titex 5057078 Screw Machine Drill Bit 0.11in

Product Description

The WALTER-TITEX 5057078 is a screw machine length drill bit designed for high-performance metal drilling in demanding trade and industrial applications. Built from Cobalt Vanadium High Speed Steel with a bright, uncoated finish, this bit delivers durability and heat resistance when cutting through hard and abrasive materials. It features a 130-degree split point, parabolic flute geometry, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The straight-cylindrical shank provides secure chuck engagement. At 0.11 inches (7/64 inch, Wire size 35) in diameter and 1-13/16 inches overall length, this bit fits standard drill presses, CNC machines, and handheld drill motors used by machinists and maintenance technicians.

This screw machine length bit is suited for drilling cast iron, steel, stainless steel, hard materials, and non-ferrous metals in production and maintenance environments. The shorter screw machine length format provides added rigidity compared to jobber-length bits, making it a practical choice for high-cycle drilling operations where hole location accuracy and tool life are priorities. It conforms to DIN, ISO, and BS standards, indicating compatibility with international tooling specifications. The Series A1148 designation places it within a recognized Walter-Titex product family used across metalworking trades.

Key Features

• Cobalt Vanadium High Speed Steel construction for heat and wear resistance in hard material drilling
• 130-degree split point reduces walking and lowers required feed force at entry
• Parabolic flute profile improves chip flow and reduces clogging during deep passes
• Web-thinned, tapered web configuration minimizes thrust load
• Screw machine length provides greater rigidity than jobber-length for improved positional accuracy
• Meets DIN, ISO, and BS standards for consistent dimensional quality

Compatibility

Designed for use in standard straight-shank drill chucks on drill presses, CNC machining centers, and handheld power tools. Primary workpiece materials listed include cast iron, steel, stainless steel, hard materials, and non-ferrous metals.

Installation Notes

Installation of this drill bit is performed by machinists and maintenance technicians using standard drill chuck tooling. Ensure the machine spindle is fully stopped and the chuck is properly tightened before beginning any drilling operation. Use appropriate cutting fluid or lubricant when drilling stainless steel or hard materials to extend tool life and reduce heat buildup. Inspect the bit for chipping or wear before each use and replace if cutting edge integrity is compromised.
