Sharpening Stone With Handle

Manual friction bricks are made of silicon carbide (Crystolon) with grooved surfaces and handles, which can be used for masonry and masonry applications, such as rubbing concrete and removing mold marks.

Main Features:

Rub bricks (also called abrasive blocks) with your hands to rub concrete and remove mold marks.

There is a chute with sharp edges on the surface of the groove, which is used to remove debris and clean the shearing effect.

Silicon carbide (Crystolon) is more corrosive than alumina and cuts faster

C20 coarse grains cut faster than abrasives with finer grains.

The firmly integrated handle is convenient for overhead, floor and wall operations.
