Can you use a smaller CNC router bit size for my parts?

We cannot use a smaller CNC router bit size to cut parts upon request. At this time, we cut all CNC routed materials using a 0.125″ bit.

All CNC routed materials are listed here.

CNC router bit tooling size. We cannot offer alternate, custom bit sizes at this time.

Expect a 0.063″ radius in tight corners due to the tooling diameter.

Rounding on inside corners due to the CNC router tooling radius.

We have more information in our CNC router design guidelines: CNC Machining Guidelines

Alternatives to a Smaller CNC Router Bit Size

If you need holes smaller than 0.125″ in your part, consider choosing a waterjet or laser cut material for your project instead. The waterjet can cut holes as small as 0.070″ in most material thicknesses, while our CO2 and fiber lasers can cut holes approximately 50% of the thickness of the chosen material.

Waterjet Cut Materials

We’ve selected the cut method that yields the best quality parts for each material. For this reason, we cannot change the cut method for a material upon request.

In Summary:

Can you use a smaller CNC router bit size for my parts?

We cannot use a smaller router bit size to cut parts. At this time, we cut all CNC routed materials using a 0.125″ router bit.
