DMT Dia-Flat 95 Plus Lapping Plate


The DMT® Dia-Flat® 95 Plus Lapping Plate is the superior choice for flattening any abrasive stone like waterstones, oilstones or Arkansas stones because of its supreme flatness and proprietary Diamond Hardcoat Technology. But what makes the Dia-Flat 95 Plus unique are the grooves in the plate. These grooves actively clear the slurry of water and stone waste that builds up while flattening, reducing the suction between the plate and water stone for a more efficient flattening experience.

The DMT Dia-Flat Plus has grooves for improved performance.

Grooves Clear the Waste

Flattening water stones creates a lot of waste material, and all that stuff has to go somewhere. On a flattening stone without grooves, this slurry of water and stone can build up and get in the way. All that stuff can create suction between the flattening stone and the stone being flattened. That can lead to the water stone sticking and becoming hard to move. The Dia-Flat 95 Plus solves this by adding grooves to the plate. The grooves sluice the waste slurry away, reducing the suction between the flattening plate and water stone, for a more efficient flattening experience.

Large 160 Mesh Lapping Plate

It is a large lapping plate measuring 10" long and 4" wide. The Dia-Flat 95 Plus uses 95 micron (160 mesh) monocrystalline diamond abrasives. If you use water stones, you know that the biggest drawback is the fact that they will wear unevenly and require flattening. It is important to keep water stones flat for best performance, especially when you're sharpening woodworking tools. The 95 micron 160 mesh Dia-Flat 95 Plus is aggressive enough to flatten water stones quickly, but leaves a smoother surface than it's coarser cousin, the Dia-Flat Plus.

Certified Flat

To properly flatten your water stones, your lapping plate must be very flat. All of the DMT Dia-Flat 95 Plus stones are carefully machined to be flat within .0005 inches. DMT takes this one step further and tests EVERY flattening stone to make sure it meets their strict specifications. If it doesn't pass the test, it does not go out. You will receive a Certificate of Flatness stating that your lapping plate has met these rigorous standards. The head of production at DMT handles this process and personally signs off on each unit.

Hardcoat Technology

The Dia-Flat Lapping Plate uses a new DMT proprietary process they call their Hardcoat Technology. DMT has been known for many years for producing long wearing diamond coated products but this is a significant step up in durability even compared with the other stones they manufacture. This is critical to the long term effectiveness of their flattening stone because the flattening process puts a tremendous amount of wear on stones compared with sharpening.
