Tungaloy 6815344 Insert Wrench 3mm Solid Carbide End Mill

Product Description

The TUNGALOY 6815344 is an insert wrench designed for use with indexable solid carbide end mills. It drives and secures the clamp screw that locks the insert in place, making it an essential service tool for toolholder maintenance on the shop floor. The wrench measures 3 mm in size and uses an IP8 Torx drive, with an overall length of 135 mm (approximately 5.3 inches). At 1 pound, it is a compact and purpose-built hand tool. Machinists and toolroom technicians use it to set or remove inserts accurately without risking damage to the clamp screw or toolholder pocket.

This wrench is intended for use with TUNGALOY Hybrid TAC series toolholders in the EVH and EXH styles. It is the correct torquing tool for clamp screw service on indexable solid carbide end mill systems in those configurations. Typical applications include insert indexing and replacement during scheduled maintenance or toolchange operations in CNC machining environments, both in job shop and production settings.

Installation Notes

This tool is installed and used by machinists or toolroom technicians performing insert indexing or replacement on CNC milling toolholders. Before servicing any toolholder, confirm the machine spindle is fully stopped and the toolholder is removed or secured. Use the IP8 Torx drive end to engage the clamp screw squarely to avoid rounding the screw head. Follow the toolholder manufacturer's recommended clamp screw torque procedure for the specific insert and pocket being serviced.
