A single blow from the spring-loaded upper platen is all it takes to straighten and true sheet metal, making it an indispensable workhorse for production and repair work alike. Both platens are hardened to Rockwell 60 (60 HRC), making them well suited for flattening non-ferrous soft metal alloys including copper, brass, silver, and gold.\u003c\/p\u003e\n\u003cp\u003eThis large-format unit — model 1127 — is engineered for years of heavy-duty use. The substantial base footprint provides stable, controlled operation, while the overall construction reflects Durston's reputation for professional-grade metalworking equipment.
