Diamond coated tools are carbide tools finished with a CVD diamond coating, built to machine the most abrasive materials, composites, graphite, aluminium and CFRP, without burning through cutting edges.
They earn their place when the material is doing more damage to the tool than your process can comfortably absorb. Short tool life, constant tool changes, slipping surface finish, dimensions that drift as the edge wears: these are the signs that standard carbide is being out-matched by the material.
The coating is applied to a carbide substrate by Chemical Vapour Deposition (CVD), creating an extremely hard, wear-resistant cutting surface while keeping the strength and toughness of the carbide body underneath.
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.
The Aero-CARB 2 Flute Double Margin Diamond Coated Drill is built for abrasive materials where standard carbide drills are not lasting long enough and the process needs cleaner, more consistent holes.
The double margin design supports guidance through the hole. The CVD diamond coating helps protect the cutting edge against abrasive wear. Together, they give aerospace teams a stronger drilling route for suitable CFRP, graphite and aluminium silicon alloy applications.
For abrasive drilling applications where hole quality, edge retention and repeatability matter.
These tools are often used when the material is wearing carbide too quickly and the process needs more consistency from hole to hole.
For milling, profiling, slotting and finishing abrasive materials where standard carbide end mills are wearing too quickly.
Diamond-coated end mills can be useful where the job needs stronger edge retention, a more stable finish, or better wear resistance across the batch.
Not every application fits a standard tool. If the job has a specific material, geometry, access issue, tolerance requirement or production target, we can review whether a custom diamond-coated tool is the better fit.

We will help you work out whether carbide, diamond-coated or PCD is the right route.
There is no universal answer. The right tooling route depends on the material, production volume, tolerance, finish requirement and cost-per-part target.
Carbide is versatile, familiar and suitable when tool wear is under control.
Diamond-coated carbide is the next step when abrasive materials start taking the edge off carbide too quickly. It can help extend tool life, support surface quality and improve consistency in the right application.
PCD is usually the strongest choice for high-volume or highly repeatable production, where maximum tool life and lower cost per part can justify the higher initial investment.
Some aluminium applications are more abrasive than others, particularly where composite structures, cast materials or surface finish requirements are involved.
Diamond-coated tooling can be useful where carbide is wearing too quickly and the process needs better consistency, cleaner cutting performance or improved tool life.
CFRP and composite materials can be unforgiving on cutting edges.
In drilling, routing, trimming and finishing operations, tool wear can affect hole quality, edge condition, surface finish and process stability. Diamond-coated tools can help improve wear resistance where conventional carbide is not holding up long enough.

Our expert team are ready for your enquiry.
Aerospace work often brings together abrasive materials, tight requirements and limited room for process instability.
Diamond-coated tooling can support applications involving CFRP, aluminium components, composite airframe parts and similar materials where wear resistance and consistency are important.
For aerospace teams, the tooling decision is rarely just about the cutter. Qualification, repeatability, documentation, stock availability and process confidence all matter. The right tool has to work in the process, not just on paper.
That is why Exactaform can support more specific aerospace conversations around tooling route, application review, qualification requirements and ongoing supply.
A diamond-coated drill and a diamond-coated end mill are solving different problems.
One may be about hole quality and repeatability. Another may be about edge life, finish, stability or wear across a milling operation.
Exactaform has built its reputation on specialist tooling for demanding applications.
We manufacture, develop and support tooling for customers who need more than a catalogue answer. That might mean a standard diamond-coated tool, a custom geometry, a PCD solution, a carbide route through WIDIA, or a completely different recommendation once the application has been reviewed.
We are large enough to support serious aerospace, automotive and industrial requirements, and small enough to bring proper care, communication and technical attention to the details.
That is what we mean by being your projects partner: looking at the job properly, telling it straight, and helping you get the right tool for the work.
Made different, delivered better.
Changing tooling affects more than the purchasing line.
It can affect setup, inspection, machine time, operator confidence and the way a process is qualified. That is why some applications need more than a quick product recommendation.
