Brazing of Carbide Mining Tools - Coal AgeFeb 23, 2012 . The high hardness is necessary for the tools to function effectively in their working environment. While the various varieties of coal are generally soft, many of the associated minerals are abrasive, causing excessive wear to metal tools. Carbide mining tools are produced by a joining process called brazing,.coal mining process carbide tool,Underground Mining - KennametalKennametal's ProPoint™ bits are slim, carbide-tipped, and designed to cut coal with better penetration and far less dust. A slimmer tool produces less dust because it cuts the coal more cleanly into larger chunks, rather than pulverizing it. Larger coal chunks are easier to sort, process, and sell. Processing coal fines, or grit,.
