What Diagrind does
Diagrind is a privately held, family-owned manufacturer of custom superabrasive internal grinding tools, founded in 1967 in the Chicago area by Ingolf Sneva, who had previously owned Ideal Carbide Die. The company designs and produces diamond and cubic boron nitride (CBN) grinding tools in a size range of .030" to 3" (CBN down to .025"), all built on carbide shanks. Its proprietary Vitreous Metal (VM) bond system, developed by the founder, remains a centerpiece of the technical offering and is one of six bonding chemistries the company maintains (VM, Resin, Metal, Vitrified, Carbide, and Electroplated), covering a broad envelope of grinding applications.
The company operates a build-to-order manufacturing model: approximately 80% of orders are custom-engineered to customer specifications, with the remaining share drawn from a standard catalog. Pricing is quote-based and sales are conducted directly to B2B customers via the company website. Diagrind operates from a single facility in Orland Park, Illinois, and serves precision manufacturers, carbide tool manufacturers, and customers in the aerospace, medical device, and automotive sectors. Its historical customer concentration sits in the U.S. Midwest (Chicago, Detroit, Pittsburgh, Cincinnati, Milwaukee), with newer content-driven outreach into Texas and California.
The business was acquired by Peter and Donald Sommer in 1975 and is now under the leadership of Michael Sommer, representing the third generation of Sommer family stewardship. Diagrind employs 11–50 people, has not raised external funding, and operates without institutional investors, characterizing it as a self-funded, specialty industrial manufacturer with a long operational track record rather than a venture-backed growth vehicle.
