What Chardon Tool does

Chardon Tool is a privately held manufacturer of single crystal diamond tools, founded in the mid-1980s and headquartered in Chardon, Ohio. The company operates two core product lines: Ultra Precision Tools (including micro milling, sharp and flat tipped tools, radius tools, lathe tools, fly cutters, aspheric tooling, and EXTREME ENDMILLS) designed for micron and sub-micron-level accuracy machining across aerospace, automotive, semiconductor, electro-optics/photonics, medical optics, and other precision manufacturing verticals; and Rotogravure engraving tools (styli, sliding shoes, burr cutters) manufactured to OEM specifications for HELL Gravure Systems, Ohio Gravure Technologies, and Daetwyler engraving systems, serving the global rotogravure printing industry across more than 50 countries. Technical differentiation rests on proprietary non-contact measuring technology, microscope-based interferometry for flatness verification, and Scanning Electron Microscope (SEM) inspection at magnifications up to 5000x, enabling quantifiable outcomes such as edge waviness as low as 0.10 micron, flat-tip widths down to 1 micron with ±1 micron tolerances, and surface roughness below 2nm Ra.

The business model is built on two revenue streams: hardware sales of diamond cutting tools (with most rotogravure orders fulfilled from stock for immediate shipment) and a Relapping Service program — including the Relap Center collection station program — that resharpens diamond tools from all manufacturers to extend tool life and create recurring service revenue. Pricing is entirely quote-based with no public disclosure, consistent with a consultative enterprise sales motion operating through direct website contact forms and phone-based engagement. Chardon Tool has 11-50 employees, no institutional investors or parent company, no funding rounds, and no M&A activity disclosed in the available source material. The company also distributes selected lathe tools through the Amazon marketplace as a secondary channel. Operating geographies span North America (USA, Canada, Mexico), Central America, South America, Europe, Asia, and Africa, with the company self-describing as the worldwide leader in development and manufacture of single crystal diamond engraving tools for rotogravure applications.
