The Sealey 680g Non Sparking Ball Pein Hammer (Model NS085) is the heaviest and most powerful option in the range, designed for substantial metalworking tasks requiring greater impact force. This weight makes it ideal for heavy fabrication, forming thicker metal sections, and demanding maintenance operations in hazardous environments where maximum striking power must be delivered without spark generation. The precision cast Beryllium Copper head provides the mass needed for effective metal shaping whilst maintaining complete spark-free operation critical in explosive atmospheres. Despite its robust construction, the fibreglass shaft keeps overall weight manageable, and the shock-absorbing rubber grip substantially reduces the impact shock transmitted to the user's hand and arm. Features and Benefits: • 680g weight delivers maximum striking force for heavy-duty applications • Ideal for substantial fabrication and forming thicker metal components • Beryllium Copper construction ensures spark-free operation in hazardous zones • Shock-absorbing grip essential for managing impact at this weight • Complies with BS 876 manufacturing standards • Lifetime guarantee provides long-term value and confidence Specifications: Brand: Premier Nett Weight: 0.905kg Weight (Head): 680g(24oz)
