T linear cuts
When turning hard materials, long and tangled chips
are produced. The HF or HM chipformers provide
excellent chip control at various depths of cut.

M • Excellent surface finishing on aluminum,
nonferrous metals and non-metal materials.
• Longer tool life in high speed machining, due to high
wear resistance and excellent thermal conductivity.
