The Industrial Kit, includes the blade, key and Pro-Guard. The ultimate powered woodcarver; the Arbortech cutting disc with tungsten tips will tackle the hardest of timbers, included reclaimed timber with included dirt and other debris. Thew Arbortech Industrial Carver is made to fit most 100mm or 115mm angle grinders, is precision machined from high quality steel and fitted with three tungsten carbide teeth. The cutting teeth are rotatable and replaceable so there's no need for sharpening. Replacement teeth are available, but with a life of almost 25 times longer than the Pro 4 it may be some time before they are required. From a purely economic standpoint the Industrial Arbortech is a sound investment. Its extreme long life, replaceable teeth and ability to cut a wide variety of materials make it excellent value for money. The Pro-Guard is a multi-purpose device which acts as a depth stop, a safety guard, a parallel guide and a chip deflector all in one.
