Walter-titex 5058689 Jobber Drill Bit 2.5 Mm Hss

Product Description

The WALTER-TITEX 5058689 is a jobber length drill bit designed for precision drilling in cast iron and steel. It measures 2.5 mm (0.0984 inches) in diameter with an overall length of 57 mm (2.25 inches) and a flute length of 30 mm (1.1875 inches). The bit is manufactured from high speed steel with an oxide coating that reduces friction and extends service life. The standard 118-degree drill point angle with web thinning promotes clean entry and reduces thrust requirements. Two spiral flutes in a regular helix clear chips efficiently during blind hole and stack drilling operations.

This drill bit is suited for metalworking applications in manufacturing, maintenance, and fabrication environments. It is used for blind hole drilling and stack drilling in cast iron and steel workpieces. The straight-cylindrical shank is compatible with standard drill chucks and quick-change systems. With a flute-to-diameter ratio of 8xD and a maximum drilling depth of 26 mm (1.024 inches), it handles through-hole and moderate-depth blind-hole work across a wide range of trade and industrial settings. It is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified trade professionals familiar with drilling equipment and metal-cutting procedures. Secure the workpiece and verify chuck torque before beginning any drilling operation. Use appropriate cutting fluid or coolant for extended runs in steel, even though this bit does not feature through-coolant capability. Inspect the drill point for wear or chipping before each use and replace if the point geometry is compromised.
