Diamond Coated Drills

Clean, controlled drilling in abrasive materials

Aero-CARB diamond coated drills are built for abrasive applications where hole quality, tool guidance and wear resistance all matter.

Designed for materials such as CFRP, graphite and aluminium silicon alloys, the range gives manufacturers practical drilling options for clean holes, stable positioning and more dependable performance across the job.

Whether you need double margin guidance, a 4 flute drill route, or a ballnose slot drill for shaped features, Exactaform can help match the tool to the material, hole and process.

Choose the Aero-CARB drill that fits the job

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.

Built for the realities of abrasive drilling

Abrasive materials ask more from a drill.

The tool needs to enter cleanly, stay guided through the hole, manage wear and support the finish or tolerance the job needs to hold. In materials such as CFRP, graphite and aluminium silicon alloys, that combination matters.

Aero-CARB diamond coated drills bring together tool geometry, diamond coating and practical application support, giving teams a standard range to review for trial, repeat use or wider tooling evaluation.

When should you choose Diamond Coated Drills? 

Diamond coated drills are recommended when: 

Machining abrasive non-ferrous materials

Drilling CFRP and composite components

Reducing wear compared to uncoated carbide drills

Improving hole quality and repeatability

Achieving longer tool life in abrasive environments

Producing components where full PCD tooling may be unnecessary or uneconomical

What these drills are designed to support

Aero-CARB diamond coated drills are designed to help with the issues that matter most in abrasive drilling:

  • cleaner, more consistent holes 
  • stronger guidance through the cut 
  • improved hole roundness 
  • better wear resistance in abrasive materials 
  • reduced disruption from repeat tool changes 
  • practical standard options for trial and repeat orders 
  • support with starting data and application review 

The value is not just the coating. It is the combination of geometry, coating, material fit and technical support.
