In 2024, Red Hill Corporation, doing business as Supergrit Abrasives, proudly celebrates its 46th anniversary. From humble beginnings in a garage in Cleveland, OH, to becoming a trusted supplier of abrasive products worldwide, Red Hill has grown significantly while staying true to its commitment to quality and customer service.
Founded in 1978 by Arturo Ottolenghi, Red Hill started as a weekend business, selling Supertack hot melt glue sticks for electric glue guns. By 1985, Arturo expanded the business to include Supergrit Abrasives, focusing on another critical product line for industries requiring finishing and polishing solutions. This decision proved to be a turning point, as the business flourished and eventually necessitated building a 22,000 sq. ft. office, store, and warehouse in Gettysburg, PA in 1995.
Today, Supergrit Abrasives has earned the trust of over 60,000 loyal customers across a range of industries, from autobody shops to marine, metalworking, and woodworking sectors. With nationwide and international distribution, the company provides essential products for both professional and hobbyist applications.
