The same angle is often needed for riveting. The MULTI-MASTER
provides an appropriate solution with its newly developed 2-flute
countersink heads (Fig. 2) with 100°-point angle in diameters
9.525-19.05 mm (.375”-.750”). The heads are also suitable for
chamfering and spot drilling.
The growth of 5-axis CNC machines has brought new efficient
strategies for milling complex 3D shapes. This has increased the
demands for cutting tools with a specific geometry, i.e., barrel
endmills. Following new needs, MULTI-MASTER replenished its
range with appropriate heads that were successfully adopted by
the customer, particularly in the aerospace, medical, and die and
mold industries.
In hole making, the recently introduced precise flat bottom
drilling heads have considerably expanded the line applicability
in shallow drilling operations for steel, stainless steel, and cast
iron (ISO P and K groups of application) including direct drilling
inclined surfaces (Fig. 3). The head diameter tolerance meets the Fig. 4 – A disc-type blank head is ideal for customized
