## Description

HHIP 6 X 8 X 2" Granite Surface Plate Grade B 0 Ledge The top surface of this plate is precision ground to achieve a high degree of flatness and the accuracy is +/-0001". It is a Grade B (Grade 1) plate. Granite surface plates meet or exceed Federal Specifications GGG-P-463C and it includes a certificate of inspection. (Note that these are not NIST traceable.) Granite plates are used for measuring the flatness and squareness of other objects, laying out parts, calibrating instruments, setting up tools, checking parallelism and perpendicularity, and measuring heights with the use of a height gage. They are also used as a work surface for assembling, inspecting, and marking parts. Non-magnetic and non-conductive. Surface plates are offered by HHIP in various sizes, with different levels of flatness and accuracy and are checked by an auto collimator for overall accuracy assurance.

Review: Stoned - Nice stone. Good price.
Review: Excellent quality and perfect for a leather stamp work base - As the title says, this was a fabulous purchase and is perfect for my leather work. The photo doesn't show it's thickness as I've countersunk it with just a small amount raised above the desk surface. I will start by saying it's HEAVY. I don't think I realized just how heavy this would be and even lowering it into the cutout compartment area was a huge feat. I will advise that if you intend to do leather stamp work on this it will require something to absorb the shock underneath. Mine is resting on a foam yoga mat like surface in a build in/converted keyboard tray slide out which we reinforced. This photo shows it with the dusty look it had upon receipt but after one quick cleaning it has not had that look any longer. It's very nicely smoothed. The edges are nice, there are no imperfections and this was just a fabulous purchase! Highly recommended.
