Made of aluminum with prisms for clamping workpieces in various shapes. Equipped with a very strong neodymium flat magnet, which is firmly pressed into the jaw and does not come loose even after prolonged use. The magnetism does not penetrate to the front clamping surface. Suitable for all types of vises. Special product advantages: The jaws are made of aluminum with a hardness between copper and lead. A horizontal prism and three differently sized vertical prisms in both jaws allow for the clamping of round and oval workpieces. The 90° recess in the upper part of the jaws enables easy horizontal clamping of flat materials. Packaging unit = 1 pair.
