The MICRO 100 QC-1 is a quick change set screw designed for use with boring bar holder systems in the QC series. This small but critical accessory secures boring bars within the holder, maintaining accurate positioning during turning, boring, and facing operations. Machinists and tool-and-die professionals rely on properly fitted set screws to prevent bar slippage and maintain dimensional consistency across tight-tolerance cuts. At approximately 0.002 pounds, the QC-1 is a lightweight replacement or supplemental component for shops running MICRO 100 QC series tooling.
The QC-1 is intended for use in machine shop environments where MICRO 100 QC series boring bar holders are in service. It is suited for CNC turning centers and manual lathes where quick change tooling systems are used to reduce setup time and improve repeatability. This set screw is typically stocked as a spare to avoid downtime when a screw is lost or stripped during routine tool changes.
Designed for use with MICRO 100 QC series boring bar holders. Confirm holder series and set screw thread specification before ordering to ensure proper fitment.
Installation is performed by machinists or toolroom personnel using the appropriate hex key or Allen wrench for the set screw drive size. Always power down and lock out the machine before changing or tightening tooling components. Do not overtighten the set screw, as this can damage the boring bar shank or strip the screw threads.
