Spring loaded jaw mechanism for positive and automatic spent mandrel release. Work Capacity- Up to 5mm/Alu and 4mm/Stainless Steel. The blind rivet hand tool Flipper^® for perfect single-handed applications is a robust and stable riveting tool complete with a spent rivet mandrel container. Single-handed operation allows you to reduce the amount of force needed for riveting by around 40 per cent. In addition, the Flipper^®features an ergonomic design because the force increases as the human hand closes – a fact which is exploited to the fullest with its special lever design for installing blind rivets. The jaw mechanism holds the rivet mandrel securely after breaking off, and you can release the mandrel once again by pressing the lever forwards. The long stroke of the tool is also useful for excessively long blind rivets.
