ALUMINIUM MACHINING
Uncoated or DLC for Aluminium?
For aluminium, the polished cutting surface, flute space and geometry matter alongside the coating.
Educational technical guide · Values must be confirmed for the actual application
Polished uncoated tools
The ALPINE ALU families use polished, uncoated cutting surfaces and wide flute spaces to support chip evacuation, clean cutting and surface quality in aluminium and non-ferrous materials.
DLC coating
According to the Alpine catalogue, DLC helps reduce material adhesion and support surface quality in aluminium. The DLC families retain a three-flute, wide-flute aluminium geometry.
Do not select by coating name alone
Alloy, operation, chip evacuation, surface requirement, cooling and tool geometry must be considered together. “DLC is always better” and “uncoated is enough for every aluminium alloy” are not universal rules.
