SF1 and SF3 Scaling Hammers

Trelawny’s SF range of scaling hammers excels at the rapid removal of heavy scale and coatings. Designed to be lightweight and easy to handle, these hammers are ideal for accessing tight spaces behind structures and up against bulkheads. The single-head model is suitable for smaller, hard-to-reach areas, while the triple-head model offers increased efficiency for larger, open spaces, delivering faster production.
