The Monument 458N Tap Reseating Tool is a professional solution for re-cutting worn tap and stopcock seats without disconnecting pipework. This essential plumbing tool allows tradespeople to restore seating surfaces efficiently, eliminating dripping taps and extending the service life of existing installations. Designed for 1/2 inch BS1010 flat seat applications, this tap reseater features tapered cones that screw directly into threaded tap bodies for secure fitment. The case hardened cutters deliver long-lasting performance, while the precision feedscrew mechanism enables fine adjustment to achieve optimal cutting depth and accuracy. The tool comes complete with 17mm and 19mm (11/16 inch and 3/4 inch) flat cutters plus a tapered cone, providing flexibility for different tap configurations. All components are interchangeable, making maintenance and replacement straightforward. For taps with recessed body threads, the parallel bush series offers an alternative mounting solution. Feature
