Hertel C.402.0590 Jobber Drill 5.90mm 118deg Hss

Product Description

The HERTEL C.402.0590 is a high speed steel jobber-length drill bit designed for general-purpose drilling in metal fabrication and machining applications. The bit measures 5.90 mm (0.2323 inch) in diameter with a 118-degree standard point angle and an oxide surface coating that provides mild lubricity and corrosion resistance during cutting. Overall length is 98.00 mm (3.86 inches) with a flute length of 67.00 mm (2.64 inches). Two right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole operations. The straight cylindrical shank is compatible with standard drill chucks across a wide range of equipment.

This bit is suited for production and maintenance drilling in steel and cast iron workpieces. Typical applications include fabrication shops, machine shops, and general industrial maintenance where a reliable, cost-effective general-purpose drill is needed. The jobber length offers a practical balance of reach and rigidity for most common hole depths encountered in trade and shop environments.

Installation Notes

Installation and operation should be performed by machinists or qualified trade personnel familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or coolant when drilling steel to extend tool life, noting this bit does not have coolant-through capability. Always wear eye protection and follow applicable shop safety standards when operating drill presses or hand drills.
