A most useful clamp for any pillar drill, especially when drilling awkward metal components. The toggle action can really apply a huge amount of pressure to the work to ensure it stays exactly where it's put. The clamps are particularly useful for securing awkward items where a vice is not really suitable and, of course, can be used in a host of different applications, not just on pillar drills. Secured to the table with a single stud and nut (supplied). Available in two sizes, the 910259 with an overall length of 150mm, 50mm from clamp pad to stud and a stud diameter of 3/8" and 910260 with overall length of 225mm, clamping length of 90mm and stud diameter of 1/2".
