Swiss Tool Systems presents a new universal boring head. The versatile Vario Head is designed for universal use, offering a boring range of 3 to 152 millimetres. An extensive array of accurately matched accessories makes the boring head ideal for different applications. The new monobloc fine drill head is compatible with standard ER collet chucks and offers rigid, centred connection. This latest product from the Swiss precision tool manufacturer can also be used for reverse drilling.

"The Vario Head provides a rigid, centred connection between the tool and the tool holder, which is easy to adjust when carrying out line boring work," states Peter Heinemann, technical head at Swiss Tools Systems. The Swiss precision tool manufacturer's new universal boring head covers a diameter range of 3-152 mm. The easy-to-use screw connection is quick to adjust and provides a conical face contact, providing stable connections in a similar way to HSK systems. The head can be used for a broad variety of tasks and the manufacturer confirms that it not only saves significant amounts of time and money, but also improves productivity.

A multi-purpose tool holder

The manufacturer's tried and trusted boring bars can still be used up to diameters of 88 mm. Thanks to the intuitive 'Push-Thru' system, the length is freely adjustable. For example, with Vario Head, boring bars can be matched precisely to the drilling depth, for optimal machining. Also, the finish-boring head can be fitted with insert holders for diameters of up to 152 mm. With diameters of 88 mm and higher, the Swiss-made Vario Head can also be used for reverse machining. To do this, the insert holders are simply mounted in reverse. No extra adaptors are needed. The system offers a totally firm connection, especially useful for improving results and accuracy after umbalances.

Inner coolant supply right to the blade edge

The diameter can be set by using the large, easy-to-read scale. Settings can be made down to a diameter accuracy of 0.01 mm, or 0.002 mm with a nonius. The Vario Head can be used with inner coolant supply. To ensure coolant reaches the blade edge - even with large diameters - matching connectors can be fitted to channel the coolant. The Vario Head is now on sale and comes as a set complete with accessories in a handy carry-case.
