The ACCUPRO 777628 is a collet nut designed for use with TG and PG 75 series collet systems. The collet nut threads onto the toolholder body to secure the collet and cutting tool in place during machining operations. It applies the clamping force necessary to hold workpieces or cutting tools with the precision and repeatability that TG and PG style toolholding systems are engineered to deliver. This part is a direct-fit replacement or maintenance spare for shops running TG 75 or PG 75 toolholding setups on CNC machining centers and manual mills.
This collet nut is suited for machine shops, toolrooms, and production machining environments where TG 75 or PG 75 collet chucks are in service. It is a standard maintenance and replacement component used by machinists and tooling technicians during toolholder teardowns, collet swaps, and spindle setup changes. The nut is sold individually, making it practical to stock as a spare or replace a single worn or damaged unit without purchasing a full collet assembly.
Designed as a direct-fit collet nut for TG series and PG series 75 size toolholding systems.
Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before removing or installing any toolholder components. Use the appropriate spanner wrench for the TG or PG 75 nut profile to avoid rounding the nut or damaging the collet seating surface. Do not exceed the torque range specified by the toolholder manufacturer for this collet series.
