Walter-titex 5058756 Jobber Length Drill Bit 4.5 Mm Hss

Product Description

The WALTER-TITEX 5058756 is a jobber length twist drill bit designed for production and maintenance drilling in ferrous materials. Ground from high speed steel with an oxide finish, it measures 4.5 mm (0.1772 inches) in diameter and 80.00 mm (3-5/32 inches) overall length. The 118-degree standard point angle and web-thinned, tapered web geometry reduce entry force and improve centering on flat or curved surfaces. Two spiral flutes in a regular helix clear chips efficiently during through-hole and blind-hole operations. This bit is installed and run by machinists, tool-and-die technicians, and maintenance tradespeople working on manual drill presses, CNC machines, or cordless drilling equipment.

The 5058756 is rated for primary use in cast iron and steel workpieces and suits blind hole drilling and stack drilling applications. The straight-cylindrical shank at 0.1772 inches diameter fits standard three-jaw chucks and collet holders without adapters. The flute-to-diameter ratio of 8xD supports a maximum drilling depth of 39.00 mm (1.5350 inches), making it appropriate for moderate-depth holes in structural steel, fabricated assemblies, and cast iron components in HVAC, plumbing, and general mechanical trades.

Key Features

• 4.5 mm (0.1772 inches) diameter with h8 diameter tolerance for consistent fit in close-tolerance applications
• High speed steel construction with oxide coating for corrosion resistance and reduced friction
• 118-degree standard point with web thinning for reduced thrust and improved centering
• Regular spiral flute, right-hand cut, suited for cast iron and steel workpieces
• Straight-cylindrical shank fits standard chucks and collet systems without adapters
• Meets ANSI, ISO, BS, and DIN specifications under Series A1211

Compatibility

Designed as an OEM-style general purpose jobber length drill bit for use in standard three-jaw chucks and collet holders across manual and CNC drilling equipment handling cast iron and steel workpieces.

Installation Notes

Install in a properly rated drill press, hand drill, or CNC spindle with the chuck tightened securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed, as a damaged edge increases thrust force and can cause bit breakage. Follow applicable shop safety standards for eye protection and chip containment when drilling ferrous materials.
