DMT Dia-Flat Diamond Coated Lapping Plate

The Dia-Flat Lapping Plate allows you to flatten waterstones, Arkansas stones, and conventional stones faster and flatter than other methods.

The steel plate is ground flat to +/- 0.0005” and has a consistent, aggressive, 120-micron (approx 160-Grit) diamond coating.  The diamonds are bonded to the plate using a proprietary process called “DMT Diamond Hardcoat Technology”, which outlasts any other diamond coating on the market.

With 40 square inches of working surface, the Dia-Flat has the largest surface area of any diamond lapping plate on the market.  The Dia-Flat is 10” x 4” x 0.375”, weight is 4 lbs.

All DMT products are made in the USA.
