MULTI-MASTER

Performance

There are two kinds of MULTI-MASTER heads intended
for milling slot and grooves: MM GRIT and MM TS.
The MM GRIT heads were originally designed for
machining internal and external grooves for various
O-rings and retaining rings in accordance with
international standards - DIN 471 or ANSI B27.7M.
The heads feature two types of cutting geometry.
The first is the general-duty K-type, which is the first
choice for milling steel and cast iron. The second is
the P-type, which is recommended for milling soft MM GRIT MM TS
and gummy materials. The heads of both types are
secured in a shank with the use of special clamping
keys. The majority of the MM GRIT heads have a W
straight tooth design with three or four teeth. r
MM TS heads with six teeth are produced with
staggered inclined teeth with larger widths of cut and Tmax
higher tooth density when compared with MM GRIT
heads of similar diameters. In order to improve chip
evacuation, increase cutting stability and reduce power
consumption, MM TS heads with wide teeth are available
with chip splitting grooves. In addition, MM TS heads
feature a TORX shaped recess on the head face for
clamping the head with the use of a TORX key.
