Barrel Shaped Endmills Expanding the Boundaries of Barrel Endmill Applications Endmills that feature a cutting edge being the segment of a large-diameter arc were introduced approximately 25 years ago. As the cutting-edge shape of these endmills is reminiscent of a barrel profile, terms such as “barrel milling cutters”, “barrel endmills” became common when referring to these types of endmills. At first, the use of these barrel-shaped mills was limited to a few specific applications, such as machining 3D surfaces of complex dies and turbomachinery components. However, advances in 5-axis...

ISCAR’s program for barrel-shaped cutters comprises tools in the following design configuration: • Solid carbide endmills. • Assembled endmills that mount MULTI-MASTER interchangeable carbide heads, and indexable endmills. These cutters differ in their capabilities and field of application. The figures and tables provide general data that relate to the cutters.

Barrel Shaped Endmills The Design Concept Advantages Solid carbide design ensures the highest tool accuracy. ISCAR offers oval and lens shaped solid carbide endmills in diameter ranges of 8 - 12mm. In addition, barrel endmills have been manufactured as interchangeable carbide heads with MULTI-MASTER threaded adaptations in the diameter ranges of 8 - 16mm. MULTI-MASTER’s distinctive “no setup time” phenomenon, which enables the replacement of a worn head without removing the tool from the machine spindle, is effective in barrel tool applications for semi-finish and finish milling operations....
