Walter-titex 5058703 Jobber Drill Bit 22mm Hss Series A1211

Product Description

The WALTER-TITEX 5058703 is a jobber-length drill bit designed for high-performance drilling in cast iron and steel. Built from M2 high speed steel with an oxide coating, this bit delivers reliable cutting life in demanding shop and field applications. It measures 22 mm in diameter with an overall length of 221 mm (8.70 inches), a flute length of 150 mm (5.91 inches), and a straight-cylindrical shank. The 118-degree split point features web thinning and a tapered web configuration for improved chip evacuation and reduced thrust on entry. This bit is intended for professional machinists, maintenance technicians, and trade professionals working with production or repair drilling operations.

The 5058703 is suited for blind hole drilling and stack drilling applications in ferrous workpiece materials including cast iron and steel. Conforming to DIN 338 and ANSI and ISO standards, it fits into standard drill chucks accepting 22 mm straight-cylindrical shanks. The Series A1211 designation places this bit in a high-performance jobber family rated for diameters 15 mm and above. Typical use cases include structural fabrication, machine maintenance, and production floor drilling where consistent hole quality and dimensional tolerance are required.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotary cutting tools. Secure the shank fully in the drill chuck or collet and verify runout before drilling. Always match spindle speed and feed rate to the workpiece material and bit diameter per standard machining references. Wear appropriate PPE including eye protection and ensure the workpiece is clamped securely before drilling operations begin.
