The Trend 33/22×1/2 Threaded Arbor is a specialist router arbor designed to accept M12×1.0 threaded bore groover and slotter blades, enabling flush corner recessing for applications such as weatherproofing and draught sealing. Spacers are included to ensure minimal arbor protrusion below the slotter blade, keeping the cutting geometry precise and reducing the risk of interference during use. This makes the arbor particularly well-suited to close-tolerance work where accurate depth control is essential. For self-guiding operations, the arbor is compatible with the Trend 33/20, which allows 12mm bore guide bearings to be fitted above the slotter blade. This extends the versatility of the setup for following straight or profiled edges without a fence.
