complete hole and bore production technology


Ohio Tool Works (OTW) a specialist honing machine tool, tooling and bore finishing application company has added Mollart Engineering to its worldwide distribution network.

These will support all major brands of bore honing machines.

The company is also a key supplier of microcrystalline and monocrystalline cubic boron nitride (CBN) abrasives and diamond abrasive tooling in synthetic and natural diamond for the finishing process. Tool geometries cover all standard heights, widths and lengths with modified standards for blind holes, hard tips, pre-radius and pre-condition requirements.
