Table 61 Maximal Width of Cut Aemax* for MULTI-MASTER Heads and
Solid Carbide Endmills Intended for HFM

Designation Max. Aemax, mm, for nom. diam.D, mm
6 8 10 12 16 20 25
MM FF… heads 7.7 9.1 13.6 17.5
MM EFF… heads 4.5 6.1 7.7 9.1 12.5 15.5 19.5
and EFF… endmills
* With the assumption that the depth of cut is Apmax, shown in Table 60

A more accurate estimatwe for depth and width of cut with respect to a workpiece material can
be obtained from Tables 62-64. The tables contain average values that work well when applied to
defining starting cutting data.
