These Magnetic - Vee blocks are invaluable and versatile in tool-making and inspection, in quality control and tool-room. Due to their extremely high magnetic power they can be used for drilling and grinding (both wet and dry) and even for light milling work. The - Blocks have a total of three magnetic surfaces. Top and bottom each with 90-degree V - angle and end surface opposite from switch. All three magnetic surfaces as well as the two sides are carefully ground. Their accuracy for flatness, parallelism and square ness is within 0.005 mm or 0.0002 inches for all work, which requires accurate positioning. When turned ‘ON ‘ all three magnetic surfaces are activated simultaneously. The permanent magnet holds the work firmly in the V and the block holds itself firmly on a ferrous surface. Coolants or other fluids cannot damage the magnetic system, being shielded from penetration of moisture. MRM - 475, 475 H, 575, 575H, 676, 676H, 856, 856H, 876, 876H, 976, 976H. We also manufacture V - blocks in 120 angle as per demand. 0 V-Blocks of 60 angle are in developing stage and will be launched soon.
