The nylon inserts for SUPERCRAFT soft-face mallets (series 3508) with their hardness of approx. 73 Shore are very hard. This white polyamide inserts offer outstanding impact qualities and are guaranteed to combine maximum strength with unique durability. They consist of extruded and extremely homogeneous material. Compared to injection moulded plastic inserts, they are therefore considerably more wear-resistant and durable and will never chip even in sub-zero temperatures. They stand up to the high impact forces produced by non-rebound soft-face mallets. What is more, they are oil and grease resistant and are also used on SUPERCRAFT sledge hammers, punches and drop-mallets. These inserts are available in sizes ranging from D10mm to D100mm.
