Product Description
The CMT 541.512.00 Spacer is a precision-ground assembly component designed to fine-tune tool positioning on spindles and cutter head systems. With an outer diameter of 20mm, a bore diameter of 12mm, and a plate thickness of 2mm, this compact spacer gives woodworkers and machinists the control they need to stack tooling accurately, adjust cutter spacing, and achieve consistent results across repeated setups.
Key Features
- Outer Diameter: 20mm - sized to seat correctly within compatible cutter head and tooling assemblies, reducing the risk of misalignment during setup.
- Bore Diameter: 12mm - fits a 12mm spindle or arbor bore, allowing the spacer to slide onto the shaft cleanly and maintain a centered, stable position.
- Plate Thickness: 2mm - provides a precise, measurable offset increment so you can stack multiple spacers to dial in exact cutter positions or stack cutters to a desired combined width.
- Designed for assembly use - intended as a dedicated assembly spacer, meaning it is engineered to hold its dimensions under repeated use rather than acting as a shim substitute.
Why This Product
- A 2mm plate thickness gives a known, repeatable offset value - making it straightforward to calculate total spacing when stacking multiple spacers or cutters without guesswork.
- The 12mm bore paired with a 20mm outer diameter provides a practical wall thickness that supports structural integrity during cutter head assembly, helping prevent wobble or play at the spindle interface.
- Sourced from CMT, a manufacturer with a dedicated line of cutter head accessories, this spacer is designed to work within that same ecosystem of tooling rather than as a generic aftermarket substitute.
- The MPN 541.512.00 is an active, stocked part - making it a reliable choice for shops that need a replacement or additional spacer without searching for a hard-to-find component.

Frequently Asked Questions
What are the exact dimensions of this spacer?
This spacer has an outer diameter of 20mm, a bore diameter of 12mm, and a plate thickness of 2mm. These dimensions are confirmed in the CMT product data for MPN 541.512.00.
What is this spacer used for?
It is designed as a spacer for assembly applications - specifically for adjusting tool or cutter positioning on a spindle, or for stacking cutters to reach a desired combined width within compatible cutter head systems.
Can I stack multiple 541.512.00 spacers together?
Yes. Because the plate thickness is a consistent 2mm per spacer, multiple units can be combined to achieve a calculated total offset. Each spacer adds exactly 2mm of spacing, allowing straightforward setup math when configuring cutter positions.
What bore size does this spacer require?
This spacer is designed for a 12mm bore, meaning it is intended for use on spindles or arbors with a 12mm shaft diameter. Verify your spindle diameter before use to confirm compatibility.
