Machine Reference by Material

Find your material below to check the corresponding ARUM machine range. Match the selected tool dimensions, stop-ring position and CAM tool definition to your exact setup.

Choose the Right Tool in 3 Steps

  • Select Your Material

    Choose zirconia, PMMA, glass ceramic or titanium premill tools according to the material you will process.

  • Check Your Machine

    Find your exact ARUM model in the material-specific machine guide. Check whether the workflow requires dry or wet processing.

  • Match Your Tool

    Compare the reference, cutting diameter, overall length and stop-ring position with your existing tool and CAM library.

Do these tools fit every ARUM machine with a 4 mm spindle?

A 4 mm shank alone does not confirm compatibility. The machine model, material, tool geometry, overall length, stop-ring position and CAM tool definition must also match. Use the machine guide on this page or contact us before ordering.

Which tools should I choose for glass ceramic or lithium disilicate?

Select the Glass Ceramic group: DG-52, DG-53, DG-54 or DG-55 references. These grinding tools require a suitable wet-processing machine and CAM strategy.

Are the titanium tools suitable for titanium discs?

The MB-58, MB-59 and MB-60 selection on this page is intended for titanium premilled blank workflows on the ARUM 5X-400. Contact us separately for titanium disc tooling requirements.

Are these original ARUM tools?

These are OnePro Dental replacement tools. ARUM machine names and tool reference codes are used to identify the intended application and corresponding tool types.

How can I confirm the correct tool before ordering?

Send us your machine model, material, current tool reference and clear tool photos. Include the cutting diameter and overall length if available, so we can help check the appropriate option.
