Cutter from the Humm Volu+ line for high-speed machining.
The tool is ideal for machining in which the entire working length of the cutter is used and high cutting speeds are used. Thanks to the use of as many as 7 blades, even more efficient processing is possible, compared to the classic Volu version. An additional advantage of the tool is the increased core diameter.
