Walter-titex 5058789 Jobber Length Drill Bit 5.9 Mm Hss

Product Description

The WALTER-TITEX 5058789 is a jobber length drill bit designed for general-purpose drilling in cast iron and steel. Built from high speed steel with an oxide coating, it resists wear and handles the heat generated during production drilling. The 5058789 measures 5.9 mm (0.2323 inches) in diameter with an overall length of 93.00 mm (3-21/32 inches) and a flute length of 57.00 mm (2-1/4 inches). The 118-degree standard point angle suits a wide range of ferrous materials. A tapered web with web thinning reduces thrust and improves chip evacuation, making it well suited to both blind hole and stack drilling applications.

This drill bit fits residential and commercial fabrication, maintenance, and manufacturing environments where consistent hole quality in cast iron and steel is required. The straight-cylindrical shank seats securely in standard drill chucks and machining center toolholders without adapters. Series A1211 tooling is targeted at professionals who need reliable, repeatable performance across repeated drilling cycles. Typical users include machinists, millwrights, pipefitters, and field service technicians drilling structural steel, brackets, flanges, and cast iron components.

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with standard drill chucks and toolholders accepting a 0.2323-inch straight-cylindrical shank. Conforms to ANSI, ISO, BS, and DIN standards.

Installation Notes

Installation and use of this drill bit is typically performed by machinists, millwrights, or maintenance technicians operating drill presses, lathes, or CNC machining centers. Ensure the workpiece is properly secured and the spindle is at an appropriate speed and feed for the material before engaging the bit. Do not exceed the maximum drilling depth of 48.00 mm (1.8900 inches) without retracting to clear chips. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
