Kenco Engineering Inc.’s Foundation Drilling Auger Protection
BY AsphaltPro Staff

Originally designed for the vertical construction industry, the foundation drilling auger protection concept from Kenco Engineering Inc., Roseville, California, can reduce downtime at the asphalt plant and at the paver by retaining auger diameter. Kenco’s unique tungsten carbide impregnated (TCI) process protects auger flights from abrasive wear. Crushed tungsten carbide (TC) is impregnated into the flight edges (and outer faces, if desired) by melting the flight metal to a depth between 0.25 and 0.375 inches and dropping crushed TC particles into the molten puddle. After cooling, the TC is solidified deep into the parent metal.
TC wear strips featuring the Kenco TCI process can be welded to flight edges and any other drill tooling that needs extra protection. It’s not an overlay or spray-on. The TC becomes a part of the steel. Kenco crushes and sizes the TC raw material in-house to maintain quality. TC has a hardness exceeding 90 Rockwell A.
