Precision-ground to a flatness tolerance of 0.127mm (0.005in) over the entire surface, this honing plate is an excellent substrate for diamond paste. Made of dimensionally stable low-carbon steel, it will retain its flatness over a lifetime of ordinary use; unlike sharpening stones, it will never need truing.
The machining process creates a regular surface pattern, imparting a very slight texture to help capture the diamond grit without compromising overall flatness. In use, the diamond particles readily embed into the softer steel, combining to form a durable, fast-cutting abrasive surface. Having a dedicated plate for each grit size used lets you work through grits progressively without risk of cross-contamination.
Plates can be glued to a backing board for ease of handling and storage. Similar in size to a regular water stone, each measures 203 x 75 x 9.5mm (8in x 3in x 3/8in and weighs just under 1.1kg (2 1/2lb).
