Product Description
CMT 2" Collar for 835.990.11 Rabbeting Bit by CMT is a precision steel bushing designed to adapt flush trim routing setups to a 50.8mm (2") outside diameter. This collar fits the 835.990.11 rabbeting bit system, giving woodworkers and shop professionals an accurate, wobble-free bearing mount for consistent rabbet depth and flush trim performance on routers and router tables.
Key Features
- 50.8mm (2") outside diameter bushing - matches the exact sizing required for flush trim applications, delivering repeatable cut depth without guesswork or adjustment.
- 12.7mm bore diameter - sized to slip precisely onto the compatible arbor, eliminating play and ensuring the collar seats squarely for accurate tool positioning every pass.
- Steel construction - provides the rigidity and wear resistance needed for demanding production routing, so the bushing holds its shape and dimension over long-term use.
- Precision-ground finish - the ground steel surface keeps runout to a minimum, which translates directly to cleaner cuts and reduced tear-out on finished workpieces.
Why This Product
- Designed specifically as a companion component for the CMT 835.990.11 rabbeting bit, this collar removes the need to source a generic bushing that may not seat correctly or hold tolerances under load.
- The 2" (50.8mm) diameter gives flush trim setups a defined reference surface, so edge profiles stay consistent across long runs of material without constant rechecking.
- Steel construction at this bushing diameter resists deformation even when routing hardwoods or dense composites, making it a reliable choice for shop environments where bits see heavy use.
- The 12.7mm bore is precision-ground to fit without slop, which means less vibration transfer to the bit and a cleaner, more controlled cut - particularly important when fine finish quality matters.

Frequently Asked Questions
Which CMT rabbeting bit is this collar designed to work with?
This 2" collar is designed specifically for use with the CMT 835.990.11 rabbeting bit. It serves as a bushing component within that system to set the proper flush trim diameter of 50.8mm.
What is the bore diameter of this bushing, and why does it matter?
The bore diameter is 12.7mm. A precision-ground 12.7mm bore ensures the bushing seats firmly on the arbor without play, which prevents wobble during routing and keeps cuts accurate and consistent.
What material is the collar made from, and how does that affect performance?
The collar is made from steel. Steel construction provides the hardness and dimensional stability needed to withstand repeated routing passes without the bushing deforming or losing its precise 50.8mm outer diameter over time.
Can this bushing be used on a router table as well as a handheld router?
Yes. This collar is compatible with both router and router table setups, making it a flexible component for woodworking shops that use the CMT 835.990.11 rabbeting bit in either configuration.
