Product Description
The CMT 541.521.00 Spacer is a precision-machined assembly spacer designed for use with cutter heads and CMT tooling systems. With an outer diameter of 21mm, a bore diameter of 12mm, and a plate thickness of 1.6mm, this compact spacer delivers exact positional control when stacking or spacing cutters on a spindle - helping woodworkers and machinists achieve accurate, repeatable results during tool assembly and setup.
Key Features
- 21mm outer diameter with 12mm bore - fits standard CMT cutter head spindle configurations, providing a secure and centered fit during assembly.
- 1.6mm plate thickness - allows fine incremental adjustments to tool positioning on a spindle, making it easy to achieve the precise spacing needed between cutters or components.
- Purpose-built spacer for assembly - eliminates guesswork when stacking multiple cutters, ensuring consistent tool spacing and reducing setup time.
- Compact and precise form factor - the tight dimensional tolerances of this spacer support accurate, repeatable tool positioning across repeated setups.
Why This Product
- When stacking cutter heads or adjusting tool position on a spindle, even a fraction of a millimeter matters - this 1.6mm spacer provides a defined, reliable gap so every setup is consistent.
- The 12mm bore is sized to work with CMT cutter head tooling systems, making it a natural fit for woodworkers already using CMT router table or cutter head assemblies.
- At only 1.6mm thick, this spacer fills the gap where thicker shims would overcorrect - giving you granular control over cutter positioning without trial and error.
- Purpose-designed for cutter head assembly, this spacer removes the need for improvised shims or makeshift solutions that can compromise tool alignment and safety.

Frequently Asked Questions
What are the exact dimensions of the CMT 541.521.00 spacer?
This spacer has an outer diameter of 21mm, a bore diameter of 12mm, and a plate thickness of 1.6mm.
What is this spacer used for?
This spacer is designed for cutter head assembly applications - specifically for adjusting tool position on a spindle and for stacking multiple cutters to achieve a desired spacing or combined width.
Can I use multiple spacers together to achieve a greater combined thickness?
Yes. Because each spacer has a defined thickness of 1.6mm, multiple spacers can be stacked together to build up the total spacing needed between cutter head components on a spindle.
Is the CMT 541.521.00 still in production?
Yes, this product is currently active and available.
