Product Description
The CMT 541.522.00 Spacer is a precision-ground assembly component designed to fine-tune tool positioning on spindles and cutter head systems. With an outer diameter of 21mm, a bore diameter of 12mm, and a plate thickness of 3.18mm, this compact spacer delivers consistent, repeatable spacing that keeps your tooling setup accurate and stable. Whether you are stacking cutters to reach a desired cutting width or adjusting the lateral position of a tool on a spindle, this CMT spacer gives you precise control over your assembly configuration.
Key Features
- Outer Diameter of 21mm - fits standard cutter head and spindle assemblies within that diameter range, ensuring a secure and stable seat with no unwanted play.
- Bore Diameter of 12mm - sized to slide cleanly over a 12mm arbor or spindle shaft, providing reliable centering so your tooling stays true during operation.
- Plate Thickness of 3.18mm - offers a specific, consistent offset that lets you dial in exact tool positioning without guesswork or shimming with non-standard materials.
- Precision-ground construction - tight dimensional tolerances mean the spacer contributes to accurate, repeatable results every time you reassemble your tooling setup.
- Designed for tooling assembly use - purpose-built as a spacer component, it integrates directly into cutter head and spindle configurations, reducing improvisation and keeping your assembly professional and reliable.
Why This Product
- When precise lateral tool positioning is critical, a purpose-built spacer with exact dimensions (21mm outer diameter, 12mm bore, 3.18mm thickness) eliminates the guesswork that comes with improvised shims or non-standard components.
- The specific 3.18mm plate thickness gives woodworkers and machinists a defined, repeatable offset - ideal for stacking multiple cutters to a desired combined width on the same spindle or arbor.
- The 12mm bore and 21mm outer diameter combination is sized to work within common cutter head assembly configurations, making it a natural fit when building or reconfiguring a multi-piece tooling stack.
- CMT tooling components are engineered to work together as a system, so using a CMT spacer in your CMT cutter head setup helps maintain the dimensional integrity the entire assembly was designed around.

Frequently Asked Questions
What are the exact dimensions of this spacer?
This spacer has an outer diameter of 21mm, a bore (inner) diameter of 12mm, and a plate thickness of 3.18mm. These three dimensions determine whether it will fit your specific spindle and cutter head assembly.
What is this spacer used for?
This component is a spacer for assembly use. Its primary purposes include adjusting the lateral position of a tool on a spindle shaft and stacking multiple cutters together to reach a target combined cutting width.
Will this spacer fit a 12mm arbor?
Yes - the bore diameter of this spacer is 12mm, which means it is designed to slide over a 12mm arbor or spindle shaft for a properly centered fit within your tooling assembly.
Can this spacer be used with cutter head systems from other manufacturers?
The source data identifies this as a CMT assembly component. Its suitability for use with non-CMT tooling depends entirely on whether the other system shares compatible 12mm bore and 21mm outer diameter tolerances - always verify dimensional compatibility before use.
