The GRS 003-021 MagnaBlock™ is a professional-grade engraving block designed for maximum stability, precision, and control during demanding engraving, stone setting, and jewelry fabrication work. Built for professionals who require a rock-solid workholding solution, the MagnaBlock combines a massive stainless-steel construction with an ultra-smooth rotating ball system to provide exceptional support and positioning accuracy. With its 30 lb heavy-duty design, the MagnaBlock minimizes vibration when using hand tools, gravers, chasing tools, and powered engraving equipment. The large ball rotates smoothly on precision bearings, while the adjustable rotational resistance allows engravers to customize the feel and movement of the block to match their preferred working style. The satin-finish stainless-steel body and black jaws reduce glare and eye strain, making the MagnaBlock an excellent choice for long engraving sessions under magnification. This model includes the MagnaBlock itself and standard components but does not include the optional attachment set.
