Walter-titex 5057093 Screw Machine Drill Bit 0.073 in

Product Description

The WALTER-TITEX 5057093 is a screw machine length drill bit designed for high-performance drilling in demanding metalworking applications. Built from cobalt and vanadium high speed steel, this bit delivers the hardness and heat resistance required when cutting through stainless steel, cast iron, hard materials, and non-ferrous metals. At 0.073 inches in diameter (wire size 49), it features a 130-degree split point and a parabolic flute geometry that clears chips efficiently and reduces heat buildup at the cutting edge. The straight-cylindrical shank provides secure chuck engagement, and the web-thinned, tapered web design reduces entry force. Licensed HVAC, plumbing, or mechanical contractors and machining professionals working in fabrication or service environments are the primary installers of this type of tooling.

This bit is suited for precision drilling in production and maintenance environments where tight hole tolerances are required. Its screw machine length profile, shorter than jobber length, increases rigidity and reduces deflection in close-quarters drilling. The Series A1148 designation places this bit within a standardized line conforming to DIN, ISO, and BS specifications. It is appropriate for use in drill presses, CNC machining centers, and hand-held power tools where a straight-cylindrical shank is accepted. Applications include drilling pilot holes, clearance holes, and through-holes in ferrous and non-ferrous workpieces across light industrial and field service settings.

Key Features

• Cobalt and vanadium high speed steel construction for extended tool life in hard and abrasive materials
• 130-degree split point reduces walking and lowers thrust force on entry
• Parabolic flute geometry promotes rapid chip evacuation and reduces heat accumulation
• Web-thinned, tapered web design minimizes cutting resistance without sacrificing core strength
• Bright/uncoated finish maintains dimensional accuracy and suits a wide range of workpiece materials
• Conforms to DIN, ISO, and BS standards for consistent interchangeability and quality assurance

Compatibility

Designed for use in straight-cylindrical shank chucks across drill presses, CNC machining centers, and hand-held power tools. Rated for primary workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel.

Installation Notes

This tooling should be installed and operated by qualified machining or maintenance professionals familiar with cutting tool safety practices. Secure the shank fully in the chuck before operation and verify chuck key removal before powering the spindle. Use appropriate cutting fluid or coolant unless workpiece material and setup dictate dry cutting. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point or flute geometry is compromised.
