Offering an insert combination of composite rubber / superplastic, the SIMPLEX series 3027 is an indispensable companion for a large number of applications and also available in two sledge hammer versions on account of the fact that it is Halder's top-selling combination: One of these versions boasts a head diameter of D80mm, a total weight of 3,170g, and a total length of 80cm. Ultra low-wear, impact cushioning and odourless, the medium hard rubber insert offers a much longer service life than a conventional rubber hammer. The superplastic insert allows for a more powerful impact force than the rubber insert. It is a medium hard plastic insert made of extruded and extremely homogeneous material. Compared to injection moulded plastic inserts, it is therefore considerably more wear-resistant and durable.
