Walter-titex 5062619 Extra Length Drill Bit 0.2874 in Hss

Product Description

The WALTER-TITEX 5062619 is a high-performance extra length drill bit engineered for demanding metal-cutting applications where standard-length drills cannot reach. Built from M2 high speed steel in an uncoated finish, it runs a 0.2874-inch (7.30 mm) diameter with a parabolic flute geometry and a 130-degree split point for aggressive chip evacuation and reduced thrust. The straight-cylindrical shank seats securely in standard drill chucks and collets. With a 16xD flute-to-diameter ratio and web-thinned, tapered web construction, this bit is built for professional machinists and toolroom technicians working blind holes and stack drilling operations where chip control and hole straightness are critical.

This drill bit is suited for production and maintenance machining in cast iron, non-ferrous metals, and steel as primary workpiece materials, with secondary capability in cobalt, iron, nickel, and titanium alloys. The extra flute length of 6.1024 inches (155 mm) and a maximum drilling depth of 5.63 inches (143 mm) make it appropriate for applications requiring deep-hole capability beyond what a jobber or screw-machine length bit can provide. It fits machining centers, drill presses, and CNC equipment in both shop and field service contexts.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals familiar with drilling operations on metal substrates. Secure the straight-cylindrical shank in a properly sized chuck or collet and verify runout before drilling. Shut down and de-energize all machine spindles before tool changes. Follow applicable ANSI and shop-specific safety procedures for speed, feed, and coolant selection when drilling deep holes.
