Hertel 4006131 Indexable Insert Drill 1-11/16 in 4xd

Product Description

The HERTEL 4006131 is a straight-shank indexable insert drill designed for precision hole-making in metal cutting applications. Built with a steel body, this drill accepts two HPMT125812-GP inserts and delivers a maximum drill depth of 6.75 inches at a 4xD depth-to-diameter ratio. The drill diameter measures 1-11/16 inches (1.6875 decimal inch), with a maximum drill diameter of 1.7380 inches. Coolant-through capability is standard, fed via a 1/4 inch threaded coolant hole at the shank end. This tool is installed and used by machinists and tool-room technicians working on CNC machining centers and manual boring mills requiring reliable, repeatable performance in production environments.

This indexable insert drill is suited for use in production machining environments where consistent hole diameter and depth control are required. The straight cylindrical shank with a 1.5000 inch diameter mounts directly into compatible toolholders and spindle systems. Right-hand cutting direction makes it appropriate for standard CNC turning and machining center setups. With a collar diameter of 1.9490 inches and a flute length of 6.9490 inches, this drill is built for medium-to-large diameter drilling in steel and similar materials.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and spindle locked. Ensure the shank is fully seated and clamped to the toolholder manufacturer specification before operation. Verify coolant line connection and flow at the shank end prior to running. Follow applicable shop safety procedures and machine-tool operating standards when indexing or replacing inserts.
