Hertel 4006145 Torx Indexable Insert Screw T6 M1.6

Product Description

The HERTEL 4006145 is a T6 Torx countersunk screw designed to secure indexable inserts in compatible toolholders. It uses an M1.6 x 0.35 thread and measures 4.20 mm (0.165 inches) in overall length with a head diameter of 0.0945 inches and a flat point. The screw belongs to the HID series and is built specifically for use in indexable insert drills. Machinists and tooling technicians use this hardware to replace worn or damaged clamping screws during insert changes, maintaining proper insert seating and cutting accuracy.

This screw is intended for use in HID-series indexable insert drill toolholders. It is a direct hardware component for toolholder maintenance in production machining environments, both shop floor and field service. The part ships in a package quantity of one screw, with a minimum order quantity of five units. It is suited for CNC machining centers, manual lathes, and drill press setups that rely on indexable cutting insert technology.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Before replacing the screw, ensure the machine is powered down and the spindle is locked or secured per standard lockout/tagout procedures. Use a calibrated T6 Torx driver to seat the screw without over-torquing, which can strip the M1.6 thread or crack the insert. Inspect the toolholder bore threads for wear or contamination before installing a new screw.
