Sine Bars and Angle Block Set

myminifactory

Machine shop tools offer various methods of holding a workpiece at the desired angle. Professional shops use standard-sized 5-inch and 3-inch sine bars to set precise angles. To utilize sine bars, gage blocks are required; refer to the instructions tab for guidance. The angle block set provides a quick alternative method of setting an angle. Triangle blocks feature pre-set angles of 5 degrees, 10 degrees, and 30 degrees, which can be stacked to achieve any angle between 5-45 degrees in 5-degree increments. By reversing the blocks, angles can be subtracted. The J-shaped holder prevents them from sliding off each other. For reference, a steel sine bar is available on Amazon at http://amzn.to/28OzfdX.
