Hertel 4006141 Indexable Insert Drill 0.787in 4xd

Product Description

The HERTEL 4006141 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. Built to the HID drill style, it accepts two indexable inserts and delivers a 4xD depth-to-diameter ratio, reaching a maximum drill depth of 3.248 inches at a cutting diameter of 0.787 inches. The steel body measures 6.357 inches in overall body length with a 1-inch straight-cylindrical shank, making it compatible with standard toolholders used in CNC machining centers and manual lathes. This tool is installed and set up by machinists and tooling technicians working in production or job-shop environments.

This indexable insert drill is suited for right-hand cutting operations in ferrous and non-ferrous materials across production machining environments. Its through-coolant capability, fed via a 1/4-inch shank-end coolant hole thread, supports chip evacuation and tool life in deeper hole applications. The 4xD ratio places it in a range appropriate for roughing and semi-finishing operations where solid carbide tooling would represent excess tooling cost. Compatible insert style is HPMT063306-GP.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the straight shank fully in a matched toolholder and verify insert seating and torque per insert manufacturer guidelines before engaging the workpiece. Ensure coolant supply lines are connected if through-coolant operation is required. Always bring the spindle to a full stop before changing inserts or removing the tool from the holder.
