⚠️ Compatibility Note

These collets are not compatible with Makita routers. While Carbide3D offers a Makita-style spindle that supports ER11 collets, most Makita routers use a proprietary collet system that does not work with standard ER collets.


Upgrade your spindle setup with the trusted collet system used across industrial and hobby CNC platforms. Whether you're dialing in tight tolerances or prepping for multi-bit projects, these collets have you covered.

Important to get balanced collet nuts at the speeds we are running. Everyone should be aware that these collets must snap into the nut before you put a tool in them. Otherwise they will runout.
