HHIP Granite Surface Plate, Grade B, 12 x 9 x 3 vs HHIP 6x6x2 Granite Surface Plate, Grade B, 0 Ledge
Overall winner: HHIP Granite Surface Plate, Grade B, 12 x 9 x 3
Key Differences
Product A (12"x9"x3") offers a larger contact area and greater thickness for heavier setups, while Product B (6"x6"x2") is more compact and sits in a lower price tier. Both are Grade B granite plates from HHIP with certificates of inspection, but neither is NIST traceable and both have mixed feedback on flatness and surface finish
