About Us

Salem Tool Company was founded by Leonard Bourgoin in 1983 in Northville, Michigan. Over the years, the company earned a reputation for excellence in CNC Machining and manufacturing high-precision, high quality machined products.  Some 20 years ago, Leonard was approached by a local engineering firm that was experiencing problems with a dynamic cone penetrometer (DCP) manufactured by a company out of state. The firm was hoping that Leonard could help resolve issues with the penetrometer, including frequent breakage and parts wearing out prematurely.

It was Leonard's ability to evaluate and troubleshoot a problem dynamic cone penetrometer that led to Salem Tool becoming a well respected manufacturer of quality soil testing products. Leonard soon introduced Salem Tool's first product, the (DCP), which has proven itself as a real workhorse, providing users with many years of reliable service.

Following this first success, the same engineering firm once again approached Leonard, this time with a dual mass DCP from the U.S. Army Corps of Engineers that was having reliability issues. Leonard and his team of toolmakers applied some of the field-proven engineering techniques that worked well in developing the Heavy Duty DCP to the Army's dual mass DCP. From this research and retooling came what many in the field today consider to be the finest, most reliable dual mass dynamic cone penetrometer on the market - Salem Tool's Dual Mass DCP.

Leonard's willingness and desire to meet customers' needs and expectations attracted customers early on. Today, a top-notch, knowledgeable team; on-time delivery; and products whose quality stands the test of time keep new customers from around the world coming to Salem Tools for their penetrometer needs.
