                 90˚ Endmill Cutting Heads


                There are two kinds of the small-diameter       greater than in the case of solid carbide
                (8-25 mm) MULTI-MASTER heads for square         endmills or MM EC… heads, so despite only
                shoulder milling.                               two teeth, the feed speed is the same as for
                                                                multi-flute mills or heads.
                The first, which is designated MM EC…, has exactly   The mentioned strength property allows even a slight
                the same cutting geometry (number of flutes,    increase of cutting speed relative to the solid carbide
                helix angle, etc.) as the solid carbide endmills.  tools/heads for the same tool life period.
                The only difference is a smaller cutting length:   This property makes MM HC… heads to be an

                The second, “economy” type, designated MM
                HC… features only two flutes and a lesser
                helix angle. Being pressed and sintered to shape
                and size, the cutting geometry of the heads
                of this type is merely finished by grinding. Due to
                the high-impact structure of a pressed tooth,
                the heads run at feeds per tooth that are significantly
