Walter-titex 5058746 Jobber Drill Bit 4mm Hss Oxide

Product Description

The WALTER-TITEX 5058746 is a jobber length twist drill bit designed for high-performance drilling in cast iron and steel. Built from high speed steel (HSS) with an oxide coating, it measures 4 mm (0.1575 inches) in diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration for improved penetration and reduced thrust. The overall length is 75 mm (2-61/64 inches), and the flute length is 43 mm (1-11/16 inches). This bit is suited for licensed machinists, maintenance technicians, and industrial tradespeople working with metal fabrication or mechanical assembly applications.

This drill bit is intended for use in blind hole drilling and stack drilling operations on cast iron and steel workpieces. It follows a regular spiral flute design with a right-hand cutting direction, making it compatible with standard drill presses, CNC machines, and handheld power drills used in metalworking environments. The Series A1211 designation places it within a general-purpose high-performance product line conforming to ANSI, ISO, BS, and DIN standards. It is well suited to shops and field technicians requiring consistent results in precision metal drilling tasks.

Compatibility

Designed for drilling cast iron and steel workpieces. Suitable for use with standard straight-chuck drill presses, CNC machining centers, and handheld power tools accepting straight-cylindrical shanks in the 0.1500 to 0.2000 inch (4.00 to 5.00 mm) diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with metalworking drill protocols. Ensure the workpiece is properly secured and the machine is at the correct speed for the material and bit diameter before beginning. Inspect the cutting edges and point for wear or damage before each use, and replace the bit if chipping or dulling is observed. Follow applicable shop safety standards and machine manufacturer guidelines when selecting spindle speed and feed rate.
