GRS 003-021 MagnaBlock Only (No Attachment)

GRS MagnaBlock (003-021) 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. This listing is for the MagnaBlock unit only — no attachment set is included.

• Heavy, stable platform: 30 lb mass dampens vibration for precise engraving and setting control.
