This HHIP 6" x 6" x 2" Granite Surface Plate is designed for machinists, inspectors, and engineers who require a highly accurate and stable reference surface for precise measurements and layouts. Its key benefit is a high degree of flatness and squareness, ensuring reliable results for critical tasks. A potential caveat is that it is a Grade B (Grade 1) plate and is not NIST traceable, meaning it's suitable for general-purpose or in-house calibration but may not meet the strictest standards for primary calibration without further certification. This plate offers exceptional hardness, non-magnetic properties, and resistance to nicks, making it a durable and versatile tool for various workshop applications.

Grade B (or Grade 1) is a standard for granite surface plates that meets specific flatness tolerances suitable for general-purpose use and many inspection tasks. It is less stringent than Grade AA or A but more precise than Grade C.
No, this HHIP Granite Surface Plate is not NIST traceable. It comes with a certificate of inspection, but for NIST-traceable measurements, you would need to have it calibrated by an accredited laboratory.
Maintain flatness by placing it on a level and stable surface, cleaning it regularly with soft materials, and avoiding impacts or placing heavy, sharp objects on it. Proper storage is also key.
Yes, granite is non-magnetic, so it is safe to use with sensitive magnetic tools or around magnetic fields without interference.
This 6"x6"x2" plate is ideal for small component inspection, detailed layout work, calibration of small instruments, and as a stable base for precision assembly tasks.
This product listing is for the granite surface plate itself. It does not typically include a stand or legs unless specified in a bundle. You will need a separate workbench or stand to support it.
Clean the surface thoroughly with a lint-free cloth and appropriate cleaner. Inspect for any foreign objects or damage that may affect flatness.
Ensure the plate is on a stable, level surface and that your instruments are properly calibrated. Check for any vibration affecting the setup.
Minor chips on the edges usually do not affect the flatness of the primary working surface. Clean the area and avoid further impact. For significant damage affecting the working surface, professional assessment or replacement may be needed.
Setup: Place the granite surface plate on a stable, level workbench or stand. Ensure the supporting surface is free of debris. For critical applications, consider a vibration-dampening pad.
Compatibility: This plate is compatible with standard metrology instruments such as height gages, calipers, indicators, CMMs, and other precision measurement tools. Its non-magnetic properties make it suitable for use around sensitive equipment.
Care: Clean the surface regularly with a soft, lint-free cloth. For tougher grime, use a mild, non-abrasive cleaner specifically designed for granite or stone, or a soft brush. Avoid dropping heavy objects on the plate, as this can cause chipping or damage the flatness. Store in a clean, dry environment, ideally away from heavy traffic areas to prevent accidental impacts.
