HHIP 4401-1597 6" X 8" X 2" Granite Surface Plate, Grade B, 0 Ledge

So smooth, so flat, so heavy. This is a perfect size and a must have for the serious knife maker or small scale machinist. When flat matters, a surface plate is a must! This will outlast me if I take care of it. Great price.

Nice stone. Good price.

Rock Solid! Great packaging! Exactly as described! Top quality granite surface plate!

This is a HHIP12" X 9" X 2" Granite Surface Plate, Grade B, No Ledge. This works very well for my tiny home machine shop. There is no ledge so care must be taken not to drop it or smash your fingers when moving it. Grade B works just fine for my purposes. Size is just right allowing enough space to measure stuff. Price was very good for the quality I received.

Item arrived in a cardboard outer box with heavy plastic strapping, inside was a wooden box. The rock itself is in perfect condition, I have no means of verifying the flatness of the surface, my intent is not a home metrology lab, but a nice flat surface to provide final dressing of woodwork tools. This will do that task very nicely. It’s pretty hefty for its size, nearly 40 pounds, so make sure to be safe when moving it around. I’m quite satisfied with it, for the price.

Received in one day. Looks fine. Best deal I found without looking too hard. The one thing people should know (and the pictures clearly show this) is that all edges are beveled with some of the corners being deeper or a bit inconsistently done. On mine it's very slight. Most likely done so they don't have to worry about chips on the edges. For a sanding surface this will make no difference but for me, square edges woud be preferable. For the price it would be hard to do better if you don't need it for the straight edge. It's well packaged in all-natural wood, paper and cardboard. : ) I find no nicks scrapes or flaws of any kind. I have no way to test for flatness. I am satisfied with my purchase.

I need to set up and measure various pieces of machinery within thousandths of an inch or hundredths of a millimeter. This granite block is flat within about 0.0001", and provides a stable, flat surface for these measurements. I can move my dial indicator without changing its baseline measurement.

Nice product.

Alles wie beschrieben

Perfectly flat and smooth

Have yet to test the accuracy, but from first impressions the quality is very good. The product arrived very fast and ahead of schedule. It came with a calibration certificate similar to the sample. Very impressed, for a hobbyist I don't think you can beat the price for the quality.

Heavy but absolutely flat and ideal for my model engineering applications.

Always wanted one, couldn't justify it. When the requirement came up I figured I had nothing to lose and I am pleasantly surprised. Very well packaged and very flat. I ran my .0001" dial on it and it's flat enough for my purposes. The "Ladoratory" Superviser on the included cut sheet agrees :)
