The Groz Ultimate Vee Block & Clamp Sets are used  for holding square or round pieces with precision during drilling, milling, and grinding operations in workshops and in layout work. These sets are manufactured from high-quality selected steel and are fully hardened and ground to ensure accuracy and durability. With an adjustable side screw with a cap in the clamp, the blocks stay in place and prevent tilting during operations. 

The clamps on these Vee blocks are within the outside width of the block making them easy to use on the base, end, or flat on either side. The blocks have four 3/8" - 16 tapped holes, two in the base and one on each side, which allow for attachment to an angle iron for use with a lathe face plate or held by a magnetic chuck.
