The traditional squeal, caused by vibrations of the individual stones within the hone-head, is now eliminated because with Apperley's 'Ranger' tooling designs, the stones are rigidly clamped in pairs to the re-useable shell type holders. Only one hone-head is needed, with a small number of shells, each slightly thicker than the next, to cover a range of diameters that previously would have required several separate expensive heads.

Apperley Honing is the UK's largest independent specialist honing company.

It manufactures and supplies honing machines, tooling and consumables as well as offering a contract honing and consultancy service to the trade. The company has a number of clients in the motor sport, aerospace, defence, oil exploration and pharmaceutical sectors.

With over 20 varieties of honing machine the company can hone diameters from 3 to 750mm diameter, in lengths of up to 15m.
