GRS 003-522 MagnaBlock With Attachment Set

GRS MagnaBlock With Attachment Set (003-522) is the top-of-the-line engraver’s block for professionals who demand strength, precision, and versatility. Its heavy 30 lb (13.7 kg) stainless-steel body and precision bearing system deliver ultra-smooth, stable rotation for engraving, stone-setting, and advanced workholding tasks.

Two industrial ball bearings plus a large roller thrust bearing eliminate play and wear for the life of the block.

The included 30-piece attachment set expands the range of shapes and objects the MagnaBlock can securely hold.
