Ohio Tool Works (OTW) — a specialist honing machine, tooling and bore-finishing-application company— has added Chessington-based Mollart Engineering (www.mollart.com) to its global distribution network, bringing a further dimension to Mollart’s deep-hole-drilling portfolio — in particular for bore-finishing tool supply.

Mollart managing director Ian Petitt said: “OTW, like Mollart, serves many of the global industrial sectors such as oil and gas, automotive, medical and hydraulic, as well as general metal working.

"Therefore, our appointment will not only broaden our deep-hole-drilling product range but also expand our customer support capability across the finishing of bores and deep holes through standard and customised honing abrasive tool supply.”

OTW has a bore-finishing history spanning over 100 years. The company has annual sales of some $12 million and an 80,000ft² facility in Ashland, Ohio.

It produces a range of vertical honing and horizontal single- and twin-spindle honing machines for the precision finishing of on-centre and off-centre bores, as well as a wide range of bore and tube hone tooling; and with an in-house capability to mix abrasives, OTW can tailor tools to suit a particular process.

The company is also a supplier of microcrystalline and monocrystalline cubic boron nitride (CBN) abrasives, diamond abrasive tooling in synthetic and natural diamond — plus honing oils.

Its OTW-VersaHone vertical machines have bore production capacities from 5.0 to 610mm (with strokes up to 1,829mm), while OTW horizontal machines have capacities from 12 to 610mm as standard, with larger diameters available on request. Full automation packages are available through Mollart Engineering.
