Applications

This radius mill is ideally suited for demanding 3D milling operations, frequently encountered in die and mold making. The tool geometry opens up flexible application possibilities for slotting, profile milling, and ramping. Thanks to its standard length, the cutter provides excellent accessibility for typical workpiece contours across steel, stainless steel, and cast iron.
Special features
A key advantage is the 35° helix angle, which noticeably minimizes vibrations and promotes a smooth cutting action. The high-performance coating reliably protects against premature wear. Consequently, the ball nose cutter supports consistently high surface qualities during finishing operations and ensures dependable process stability in daily use.
