Diamond coated drills are carbide drills finished with a CVD diamond coating, used to drill abrasive, non-ferrous materials such as CFRP, graphite and aluminium-silicon alloys, where standard carbide wears too quickly to hold hole quality and tool life.
In these materials a diamond-coated edge stays sharp far longer, keeping hole finish, dimensional accuracy and repeatability under control across the run, rather than drifting as the tool wears.
The right drill depends on the job: double margin guidance, flute count, router or ball nose geometry all change with the material, operation, tolerance and finish you need. Exactaform helps match the drill to the material, hole requirement and production environment, so you can choose the right Aero-CARB option with confidence.
Different drill styles exist because different applications need different behaviour.
The right option depends on the material, operation, tolerance, finish requirement and how the tool needs to behave in the process.
New to the Aero-CARB Range, the 2 Flute Double Margin Diamond Coated Drill is built for abrasive drilling applications where standard carbide is not lasting long enough and process stability matters.
With new size options and diamond-coated wear resistance, it supports cleaner, more consistent holes in suitable aluminium silicon alloys, CFRP and graphite applications. The double margin design provides added guidance through the hole, helping manufacturers improve drilling confidence in demanding materials.

Aero-CARB diamond coated drills are designed to help with the issues that matter most in abrasive drilling:
The value is not just the coating. It is the combination of geometry, coating, material fit and technical support.
