Vehicle manufacturers are favouring the use of cold riveting, allowing different materials and various layers to be more easily bonded together. With this in mind, Tri-Sphere has upgraded its SPR hydraulic riveting tool to comply with the latest specifications. This model has a trigger rather than a foot-driven mechanism making routine jobs that bit simpler. It delivers up to 50kN of driving force and can work with high strength steels and the C-shaped head includes a 38mm pitch. A pressure gauge enables you to ensure the right pressure is applied to each type of material. Large clamps are available to deal with larger panels and twelve upper and lower mandrels are included with two sets of magnetic inserts.
