                 MULTI-MASTER Endmill Heads


                 MULTI-MASTER is a family of tools with shanks and interchangeable cutting heads for a variety of
                 machining applications: milling, countersinking, spot and center drilling, and slitting.
                 A MULTI-MASTER head has a cutting part and a back connection with the external thread and
                 the taper, which screws into a shank with the corresponding internal thread and the taper until final
                 securing when the back face of the head cutting part will contact the face of the shank.
                 This principle of coupling ensures strength and rigid clamping of a wide range of the
                 interchangeable heads. The MULTI-MASTER tools meet the requirements of high accuracy
                 because the head geometry is finished by precise grinding and the connection guarantees high
                 concentricity within very close limits. The tools are simple-to-operate because the heads are
                 quickly replaced by easy rotation of an applied key. Moreover, they answer to strict requirements of
                 repeatability, and thus, replacement of the heads does not require additional adjustment.

                 The MULTI-MASTER family features a large variety of heads, shanks and extensions. The basic
                 concept is, when a shank can carry heads of different shapes and accuracy, this allows dramatic
                 increase of tool versatility and will diminish needs for special tools. A large stock of tools is not
                 necessary. Resharpening of tools is no longer needed, because a worn-out cutting head is simply
                 replaced. The family renders a possibility of numerous tools by an unlimited combination of the
                 heads and the shanks, and therefore, excellently answers the demands of die and mold making
                 and reduces procurement cost.






                   No setup time advantages
                   Repeatability of an assembled mechanical system with interchangeable elements means that a key
                   parameter of the system remains in agreed limits in case of replacing an interchangeable element of
                   the same type. For the standard MULTI-MASTER tools, repeatability in tool length is about 0.04 mm
                   for the milling heads of normal accuracy and about 0.02 mm for the precise milling heads.
                   That is why there is no need for additional adjustment in tool length after replacing a head; and the
                   head can be replaced when a shank remains clamped in a machine tool spindle without new
                   presetting. No setup time for replacement considerably cuts cycle time and is a good source
                   for increasing productivity.








                   Indexable solid carbide tools
                   The endmills that are assembled from the MULTI-MASTER heads and shanks open 3 doors to
                   saving money and improving productivity. MULTI-MASTER modular tools, which are neither solid
                   carbide nor indexable tools in a popular sense, lay in the intermediate field between them.
                   Having a replaceable solid carbide cutting part they relate to a new type of cutting tools: indexable
                   solid tools, unlikely as it may seem with the combination of the words “indexable” and “solid”.
