Jerry and Norma Russell purchased the company in the early 1980’s, and today Helro Corporation is a third generation family-owned manufacturer that still operates in the greater Detroit area. In the mid 1990’s, Helro engineers developed a process to manufacture diamond grinding wheels.

Our unique Molecular Diamond Bond, MDB ®, allows customers to grind rubber cooler and faster, which improved our customers’ productivity and bottom line. Other designs and patents include an innovative Power Transmission Belt Profile; Surface Coating Treatment of Grind Wheels; Hybrid Cutting / Grinding Tool; and the Inserted Profile Cutter.

Our engineers are constantly looking for ways to solve our customers’ problems and improve product and productivity.
