Combination of flute shape that focuses on cutting performance and our original DLC coating achieves improved machined surface quality.
Mitubishi Hitachi Tool : Epoch CFRP End Mill
ECH-SD
Type H- ・Left helix 30°
- ・SD coating
・Sharp cutting flute is expected to reduce cutting force and improve efficiency and machined surface quality.
・Left-hand helix suppresses burrs on top surface of work.

ECX-SD
Type X- ・Tip：30° Right helix; Flute base：30° Left helix
- ・SD coating
・Sharp cutting flute is expected to reduce cutting force and improve efficiency and machined surface quality.
・Flute with different helix at tip and flute base suppresses burrs on top and bottom surface of work during trimming.
・Sufficient chip pocket even at the switchover between helix on the cutting flute enables the prevention of chip clogging.
