This is nice. Utah on my review.

This stone is nice and flat even shipped it with the good part upside down with a really nice thick film with heavy duty plastic in a pine box which I find to be fascinating that they did awesome. Anyway ebay thank God they shipped it to the wrong house and it sat there for a whole Flippin day until I realize that it was here a day early ha ha ha ha the wrong house really kind of pissed me off but there is a scratching the surface but it’s manageable thanks China for actually shipping…

Pros
  • Use for checking flatness of machined parts. Received quickly and in perfect condition.
Cons
  • The absence of a ledge means that there is no way to easily clamp down material for measurement, limiting its versatility

Not as described in title.

Description is incorrect. The title description calls this a 2 ledge plate. It is a "no ledge” plate. The pictures are correct. I thought the item would be shipped as described not as pictured. Buyer beware.

Pros
  • Packaged well. Item delivered was exactly as described.
Cons
  • Without a raised edge, there is a slight risk of materials slipping off the surface and causing damage

Flat, heavy, exactly what you want

Found this product (12x9 x3”) for almost the same price as shipping from other websites ($68, 07/05/2022). Description says flatness of 0.0001” and my measurements concur with that of the stated. As such, great product, great price. 5 stars.

Pros
  • Industrial & Scientific
Cons
  • Granite surface plates are not scratch-resistant, meaning they can develop scratches and blemishes over time that may affect their accuracy

Only 1 side flattened

The other side wasn't flattened. Not even close so you can never flip this over and use the other side. It doesn't sit flat either. Debating on returning.

Pros
  • {}
Cons
  • The material used for this surface plate is not magnetic, limiting its compatibility with certain measuring tools

Flat Granite - my new review

Well if your needing something that's truly flat than this is well worth the money and shipping was very fast Thanks for attention.

Pros
  • Practically Maintenance Free and Won't Corrode Like Steel
Cons
  • Granite surface plates may not be suitable for use in extreme temperatures, as the material can expand and contract with heat and cold

measured better than spec

extremely smooth and dense granite. Not able to measure hardness so time will tell. Measured better than spec. My dial gage flatness fixture showed better than 0.00005" all ways.

Pros
  • Flat. Well packaged. Is exactly what you need it to be.
Cons
  • The size of this surface plate may be too small for larger projects, requiring multiple measurements and recalibration

As flat or flatter than anything I have to check it with

* well packaged, double boxed plus a thin wooden box, good enough* delivered by amazon, good delivery, very heavy, good job amazon, free delivery* as flat or flatter than anything I can check it with* checked flatness with a Kinex 4033-12-020 Flat Solid Machinist Square 8" x 5.25" DIN 875/1 and it was perfect everywhere in every direction* checked flatness with an inexpensive but new Irwin straight edge (good enough for lots of work) and the flat granite surface made the Irwin straight edge…

Pros
  • Test, Measure & Inspect
Cons
  • The weight and size of this surface plate may make it difficult to store or transport, particularly for those with limited space in their workshop

It's definitely flat

I'll admit, I was a bit concerned at first. I laid my straight edge across the surface and could see light shining through underneath. However, I used my smallest feeler gauge (0.015" / 0.04mm) and couldn't slide it under the straight edge anywhere.Is it flat within .0025mm as they claim? Probably not. It's definitely better than 0.04mm though and that's perfect for my needs.

Pros
  • For General Inspection Work Throughout The Shop
Cons
  • This surface plate may require additional accessories like clamps, gauges, and indicators to be properly used, which can be an added expense

Great homeshop surface plate

Great deal for home workshop.delivered in a wooden box.undamaged in shipping.would recommend for someone just getting started into machinist work or knife making.

Pros
  • Perfect for tooling, unbeatable value
Cons
  • Granite is a porous material, which can harbor bacteria and become stained over time if not cleaned properly
