GRS MagnaBlock Engraving Block Ball Vise
The increased size and added weight of the GRS MagnaBlock ball vise provides extra support for your work. Weighing 30 lbs., this extra-heavy block delivers the stability you need when using power tools or chasing hammers. The crown rotates smoothly over roller bearings and the crown shaft turns within ball bearings to eliminate wear and loosening. Rotational resistance is adjustable for fine-tuning your work. All surfaces are specially finished for low glare to reduce eye strain. Vice jaws have replaceable threads. Every major part is machined from solid steel stock. Furnished with a rubber pad, jaw plates, 5 steel pins (four 9/64" pins and one 1/4" pin), and wrench. The included 30 piece attachment set adds a variety of pins and clamps to hold just about any item you might want to engrave (see related products below). Made in USA.
