Diamond tools for valve balls and brass fittings
A ball valve seals well only if the ball is smooth and round. On brass, a single crystal diamond tool gives that mirror surface in the final pass, ready for plating. Bulunmaz makes ball finishing tools and brass turning tools in natural diamond and MCD, as standard tools or to your drawing.

When diamond is the right choice
Single crystal diamond is for the final mirror pass on brass, including low-lead brass. Roughing, drilling and threading are done with carbide or PCD, and stainless steel balls are not a job for diamond. Tell us your material and we'll confirm.
Who we supply
Bulunmaz makes and supplies diamond tools for valve and fittings makers that run their own machines. We do not machine valve parts for customers, and we do not sell ball machines. If you run the machine, we supply the tool for it.
