Hertel 4006107 Indexable Insert Drill 1 in 3xd

Product Description

The HERTEL 4006107 is a straight-shank indexable insert drill designed for high-productivity hole-making in metal cutting applications. The body accepts two indexable inserts and is built to a 3xD depth-to-diameter ratio, allowing a maximum drill depth of 3 inches in standard use. The drill diameter is 1 inch (25.40 mm) with a 1.25-inch straight-cylindrical shank. Coolant-through capability is included via a 1/4-inch threaded coolant port at the shank end, supporting chip evacuation and heat management in interrupted or deep-hole operations. The tool body is steel construction. Insert compatibility is specified for the HPMT074006-GP insert family.

This indexable drill is suited for CNC machining centers and turning centers where repeatable hole diameter and depth are required without regrinding. The 3xD ratio is a standard selection for general-purpose drilling in steel, cast iron, and similar ferrous materials. The straight-cylindrical shank allows direct clamping in ER collet chucks, hydraulic chucks, or milling machine spindles with appropriate bore size. This tool is typically set up by machinists or tool-room technicians on production or job-shop equipment.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool changer or turret is in a safe, locked position before mounting or removing the drill body. Confirm insert seating and screw torque per the insert manufacturer's documentation before running the tool. Verify coolant-through passages are clear and coolant pressure is within the machine specification before engaging the spindle.
