Tos Hostivar circular grinders

Tos Hostivar (Holmonta) in the Hostivar district in Prague manufactures modern grinders with diameters of 250 mm – 1000 mm. The machines’ range of distance between centres is 630 – 6000 mm and they are equipped with CNC or NC control. TOS Hostivar grinders form the basis of these machines, with some modifications and improvements to make them even more effective.

Tos Hostivar modernises older machinery, making CNC and NC versions of them, and also refurbishes all types and sizes of grinding machinery.

HOL-MONTA carries on the tradition started by Tos Hostivar

Since 1992, HOL-MONTA has continued manufacturing TOS Hostivar grinders and managed to add their own experience and expertise to improve the machines even further. The company closely monitors the latest developments in grinding technologies, uses modern CNC systems in their production, and utilises electrical and other components by European manufacturers.
