The Groz Articulating Arm Magnetic Bases are a top-quality tool for any machinist or engineer. The base features a rigid and robust construction, making it able to withstand heavy use in the shop. The unique design of the base allows for a dial indicator with both 3/8" and 8 mm stems, as well as test indicators with a dovetail clamping mechanism, to be set at any desired position. 

The base features three articulating joints that can be locked using a single knob, providing an impressive working angle of 150°. The base also features a Vee groove that securely fastens on round ferrous jobs or machine tables, providing a stable and secure base for measurement. These come without a dial gauge
