About

Precision machines & accurate made-to-order tooling for tight tolerance alloy steel & ceramic applications

We currently feature Takezawa-Seiki brand Diamond Reamer Tools and Floating Holders. Takezawa Diamond Reamers are all made-to-order in their factory in Tochigi Japan. The Takezawa Diamond Reamers range in size from 3/32" to 6" (2.5mm to 150mm) and are time-proven to deliver superior accuracy with extended tool life in demanding low-tolerance honing applications in alloy steels, aluminum, bronze, brass cast iron & ceramics.

In 2023 we also acquired all rights and IP to the legacy Taper Boring Tool, first made by TREE Machine in the 1950s. The TB-4 enables tapers to be machined on traditional manual vertical and horizontal milling machines.
