High Quality Washover Shoes for Well Drilling
Construction
Our Washover Shoes are dressed with a special hard-face compound made of crushed sintered tungsten carbide particles and a resilient matrix of nickel-silver alloy. Tungsten carbide particles have a hardness nearly equal to that of diamonds. They retain their hardness at high temperatures and are not affected by the heat generated from the cutting operation. The tough nickel-silver alloy matrix holds the tungsten carbide particles in place and cushions the particles against strong impact.
