DMT 12″ Double-Sided DiaSharp MagnaBase System

Up your sharpening game (off the bench) with The DiaSharp Magnabase Sharpening System from DMT. The system features a 12″ double-sided DiaSharp stone, and a magnetic base that lifts the stone 2″ off the work-surface. The uninterrupted diamond abrasive is precision flat, and works well with sharpening jigs, the hardest alloys, and pointy or narrow tools. Sharpen with a splash of water, or dry for zero cleanup.

The MagnaBase System is available with Fine/Extra-Fine or Coarse/Extra-Coarse double sided DiaSharp stones. Switching between grits is as easy is flipping the stone. Both grit combos feature DMT’s signature dense and even coating of micronized mono-crystalline diamond bonded to a solid steel surface, and nickel plated for durability.

DMT’s DiaSharp diamond sharpening stones have a continuous surface that is our favorite diamond abrasive for sharpening in the wood-shop because they stay flat, and cut quickly. For tough jobs like sharpening a D2 mortise chisel, or resetting the bevel on a gouge, the DiaSharp is hard to beat, and the fact that it will remain flat means you can work the back of a chisel right afterwards without worry.

The Magnabase System is a great addition to the DiaSharp range. The bases are not available separate from the stones, but will hold any DiaSharp stone in your collection.

The Double Sided DiaSharp stone measures 3″ by 12″ by .35″

The Base has a slightly narrower 2.65″ by 12″ Magnetic Surface and is 2″ tall.

The DMT DiaSharp MagnaBase System is Made in the USA.
