LMI Binding Router Bit + Bearing Sets
A trusted classic, now available exclusively at StewMac!
We don’t often talk about the competition—but sometimes, a competitor just gets it right. The LMI Binding Cutter is one of those tools. Originally developed by our longtime friends (and competitor) Luthier’s Mercantile International (LMI), this system earned a loyal following from both builders and guitar techs for good reason.
Built around a premium Whiteside cutter and paired with high-quality, long-lasting sealed bearings, it gives luthiers the control and precision they need to cut flawless, consistent binding and purfling channels. Whether you're just starting out or replacing parts on an LMI setup you've used for years, this system delivers everything you need: reliability, flexibility, and simplicity.
Now available only from StewMac.
Individual LMI Binding Router Bearings can be purchased separately.
Please note: StewMac and LMI brand binding tools are not cross compatible with each other.
Pro Tip: The low-mounted bearing position on this cutter helps it stay aligned with the guitar body’s side—especially helpful for deep channels or rebinding work.
