Tungaloy's DoTwistBall insert is designed for demanding 3D profiling and high feed applications

Tungaloy is expanding its DoTwistBall line of profile milling tools, to include new insert radii. The line allows 2 different types of inserts to fit the same cutter body, each dedicated to profiling and high feed application. The insert is constructed in a helically twisted structure which fits the seat pocket constructed in a matching helical profile. This Twist Clamp system helps maximize insert retention, making DoTwistBall an ideal tool to ensure stable machining in demanding 3D profiling and high feed applications. The centrifugal forces on a rotating tool act to try to throw the insert from the pocket.

Due to the overwhelming demand for the current 04 (R4.0) style insert, the 05 (R5.0) and 06 (R6.0) style inserts are now added to the standard line.

The radius insert in the -MJ geometry features a large cross section designed to absorb the brunt of the cutting force, providing higher reliability over the conventional round inserts. The high feed insert in the -HJ geometry promotes highly efficient machining through 30% greater cutting depth and feed rate over the conventional high feed inserts.

Two standard grades include AH3135 for steel and stainless steel as well as AH120 for cast iron, hard or difficult materials, covering a wide range of materials.
