HHIP 4-1/2 x 3-1/2 x 3 in Slotted Angle Plate vs HHIP granite surface plate 6x8x2, grade B, with certificate

Overall winner: HHIP granite surface plate 6x8x2, grade B, with certificate

Key Differences

Product A (granite surface plate) is a precision ground Grade B plate with an inspection certificate and higher average rating, suited for high-accuracy surface-flatness and calibration tasks. Product B (slotted angle plate) is a machined, slotted angle plate designed for clamping, layout and inspection with wider versatility for fixturing but reports rough surface finish and mixed squareness on tertiary faces
