Founded in 1994, Kelmar Diamond Tool Supply — formerly Kelmar Tool Inc. — is a family-owned business built on deep expertise in the manufacturing of PCD, CBN, and natural diamond tooling.
From the start, our modest operation earned a strong reputation for exceptional quality and rapid turnaround times, becoming a trusted private-label source for many of the industry’s leading diamond tool manufacturers — including major suppliers to the automotive and aerospace sectors.
A family crisis required us to step back from full-scale operations. Though we are no longer operating at our former capacity, we have retained a small, highly skilled crew — each with extensive hands-on experience in precision diamond toolmaking.
Today, we maintain a substantial inventory of major brand-name cutters, cartridges, and inserts, and continue to offer the capability to manufacture Kelmar-branded tooling and inserts to our exacting standards.
We take immense pride in the precision and reliability of every tool that bears our name. At Kelmar, quality is not just a standard — it is who we are.
