Established in 1958, Boston Centerless has earned a reputation through the years for unequaled quality and service. Our unique application of proprietary grinding competencies, lean management systems, Core Values and national scale have resulted in our ability to manufacture ultra-precise ground bar materials and technical solutions which provide unmatched downstream savings for our customers.

When the company was founded, it provided thru-feed centerless grinding services. Over time, we determined that there was a distinct need for accuracy ground bar stock for Swiss screw machining and other precision machining applications. To better manage the quality and consistency of size tolerance, straightness, roundness and surface finish, we formed the AccuRod® Division.

In addition, the GrindAll Division provides grinding services on customer supplied components and material, and the PinGage Division manufactures ultra-precise gages.

Boston Centerless has a 45,000 sq. ft. state-of-the-art facility located in Woburn, MA, with a large inventory of materials as well as distribution centers located in Massachusetts, Minnesota and Ohio. At Boston Centerless, we hold the perfect balance of modern technology combined with years of experience.
