Who We Are

We build the products your customers bet their business on

Pentagon was established as a custom machine tool builder in the 1970s, supplying purpose-built machines to India’s leading automotive OEMs. These strong foundational roots enable us to design and manufacture all our own jigs, fixtures, and gauges in-house, along with a strong maintenance team that can strip, rebuild, and customise machine tools from first principles.

Operations are split across two plants in Ambattur Industrial Estate, Chennai. Plant 1 houses machining, assembly, testing, and administration. Plant 2 is a dedicated gear-cutting division. Total footprint is 43,200 sq. ft., of which 20,000 sq. ft. is currently built-up, with the balance ready for expansion as customer programmes grow. Both plants are ISO 9001:2015 certified.

Pentagon is now in its second generation of management, with the third generation joining the business. Line managers and senior staff have, in many cases, spent over two decades with the company.
