Description

The Dümmel Ultramini tool-line is a must for turning smallest bores.
The inside bore machining of small diameters has always been difficult and it is not easy to obtain the ideal tool.
The Ultramini tool-line covers more than 1.000 different standard inserts which could be clamped in only two toolholders.
Of course the complete Ultramini program is available on stock.
