<p>The clamping device 1 includes a first clamping face 2 at least partly formed from a ferrous or ferromagnetic material and a second clamping face 3. An adjustment means 5, 6, 7 is arranged in use to connect between the first and second clamping faces and configured to be user-operable so that the faces can be positioned in opposition to one another and so as to alter the distance between the opposed faces 2, 3. At least one magnet 4 is associated with the first clamping face to provide a magnetic flux through the first clamping face so that a ferrous or ferromagnetic work piece can be magnetically attached to the first clamping face 2. A user-operable switch (15a, Figure 5) may be mounted on a clamping head to move the magnet/s between first and second positions. The clamping head may also include a container of non-ferrous material to at least partly contain the magnet.</p> |
