Walter-titex 5058669 Jobber Drill Bit 18mm Hss Oxide

Product Description

The WALTER-TITEX 5058669 is an 18 mm (0.7087 inch) jobber length drill bit manufactured from high speed steel with an oxide coating. Designed for right-hand, spiral-flute drilling, this bit carries a standard 118-degree point angle and a web-thinned, tapered web configuration for improved chip evacuation and reduced thrust at entry. The straight-cylindrical shank measures 0.7087 inch in diameter, making it compatible with standard drill chucks. Built to ANSI and ISO standards and rated for general-purpose to high-performance applications, the 5058669 is a reliable option for trade shops and production environments handling cast iron and steel.

This drill bit is suited for blind hole drilling and stack drilling operations in cast iron and steel workpieces. The Series A1211 designation places it within a well-established jobber length family. With a flute-to-diameter ratio of 8xD and a maximum drilling depth of 4.409 inches (112 mm), it handles moderate-depth holes without step drilling. It is appropriate for use in CNC machining centers, drill presses, and hand-held power tools in metalworking, fabrication, and maintenance applications. Licensed machinists, millwrights, and maintenance technicians are the typical end users.

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit in Series A1211, compatible with standard straight-cylindrical chuck systems. Primary workpiece materials are cast iron and steel (ISO material codes K and P).

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with metal cutting operations. Secure the straight-cylindrical shank firmly in a keyed or keyless drill chuck rated for the shank diameter before operation. Shut down and de-energize all machine power before inserting or removing the bit. Always use appropriate cutting fluid or coolant for the workpiece material unless operating under dry-cutting conditions specified for the application.
