GRS 003-021 MagnaBlock Only (No Attachment)

GRS MagnaBlock is a premium, heavy-duty engraver’s block engineered for stability, precision, and longevity. Two industrial ball bearings plus a large roller thrust bearing eliminate looseness over the life of the block. Hardened steel jaws use an exclusive rebuildable thread system, and the satin-finish stainless body with black jaws helps reduce glare and eye strain. At 30 lb (13.7 kg), MagnaBlock offers rock-solid support for engraving, stone setting, and demanding workholding.
