The advantages of the HFS® Head Fitting System and the opportunities this provides for manufacturing, use and preparation of reaming heads are decisive to the success of these new tool series. Simple, easy access handling when changing tool heads, high flexibility with regard to special designs, a variety of cutting materials and diameters from 4 mm in the standard programme provide a large range of possible applications. As a result of the direct coolant supply onto the blade, the system is also extremely well suited for use with minimal or micro lubrication (MLC).
