GRS 003-774 MicroBlock XL with 30 Piece GRS 003-520 Attachment Set

The GRS MicroBlock XL expands on the proven MicroBlock design with additional weight and enhanced functionality. At 7 lb (3.18 kg) with a 100 mm ball diameter, it fills the ideal size gap between the GRS MicroBlock and the GRS Standard Block. The XL version retains full compatibility with all standard MicroBlock jaws and attachments — including Jura Microstonesetting Tools — so your existing tooling investment carries over without compromise.

The MicroBlock XL is well suited for stone setting, small-to-medium engraving work, and other precision tasks. Its low profile makes it particularly compatible with microscope setups. An internal rotational brake system allows the user to dial in resistance anywhere from completely free-spinning to fully locked, providing precise control throughout the work. Two bases — one rubber, one plastic — are included to optimize grip and feel across different work surfaces.

This version includes the GRS 003-520 30-piece attachment set, expanding the versatility of the block right out of the box.
