961 Series

Tool 961i0812B

Access restricted undercuts without repositioning the workpiece. The 961i0812B extends spherical contact to 300 degrees for deeper profile engagement than standard ball nose geometry.

Four flutes balance surface finish with material removal rates in steel and aluminum applications.
The 0.117" neck diameter provides clearance while maintaining rigidity at the 0.1875" cutting diameter.
AlTiN coating handles the elevated temperatures generated during extended ball contact, particularly when machining steel alloys where friction increases with contact area.
The extended spherical geometry reaches profile angles that typically require multiple setups or specialized fixturing.
Heat dissipation becomes critical as contact area increases, making the coating selection essential for maintaining edge integrity during complex 3D profiling operations.
