MULTI-MASTER Threading Heads

• MULTI-MASTER is a family of tools with shanks and interchangeable cutting THREAD MILLING
heads for a variety of machining applications for thread milling.
• The MULTI-MASTER design approach is based on a thread profile system, centered by a short precise
taper and face contact. A MULTI-MASTER head has a cutting part and a back connection with external
thread and taper, which screws into a shank with the corresponding internal thread and a taper, until
final securing when the back face of the head cutting part makes contact with the shank face.
• This principle of coupling ensures straight and rigid clamping of a wide range of interchangeable heads.
MULTI-MASTER tools meet the requirements of high accuracy because the geometry is finished by precise
grinding and the connection guarantees high concentricity within a very close limit. In addition, the tools are simple
to operate because the heads are quickly replaced by easy rotation of an applied key. Moreover, they conform
to strict repeatability requirements and replacement of the heads does not require additional adjustment.
• The basic concept of the MULTI-MASTER Family is that a shank can carry heads of different shapes and accuracy, allowing
dramatic increase of tool versatility and fewer needs for special tools. Resharpening of cutting edges is no longer needed as
a worn out cutting head is simply replaced. The MULTI-MASTER Family provides a range of possible tools by an unlimited
combination of heads and shanks, which answers to any thread making requirement and reduces procurement costs.
