Product Description
The CMT 799.503.00 Aluminum Bushing with 3/4" Diameter is a precision-made collet and bearing accessory designed to adapt bore sizes on compatible CMT router bits and tooling. With a 19.05mm outer diameter and a 12.7mm bore, this bushing serves as a reliable reduction collar that keeps your router bit centered and stable during operation - eliminating wobble and ensuring consistent, accurate cuts on every pass.
Key Features
- 3/4" (19.05mm) Outer Diameter - matches the collar seat precisely on compatible CMT tooling, including the 8/935-900 router bit, so the bushing seats without play or misalignment.
- 12.7mm Bore Diameter - reduces the internal opening to accept smaller-shank tooling configurations, giving you flexibility to use the correct bit in the correct collet position without improvising.
- Steel Construction - a durable metal material that resists deformation under the rotational forces generated during routing, keeping the bushing intact and true over repeated uses.
- Precision-Ground Fit - the bushing is manufactured to tight dimensional tolerances, which means accurate, wobble-free bearing and collet mounting every time you install it.
- Compatible with CMT 835.990.11 - designed specifically as a 3/4" collar for this CMT model, removing guesswork about fitment and ensuring the bushing works as intended right out of the package.
Why This Product
- Designed as a direct-fit accessory for the CMT 8/935-900 router bit and the CMT 835.990.11 collar, so you can be confident the bushing will seat correctly without modification or shimming.
- The 12.7mm bore paired with the 19.05mm outer diameter provides a meaningful size reduction for adapting collet and bearing bore configurations, solving a common fit mismatch without needing a different router bit entirely.
- Steel construction holds up to the demands of repetitive routing passes, making this a dependable long-term addition to your CMT tooling system rather than a single-use workaround.
- Precision-ground tolerances mean the bushing contributes to accurate tool positioning, which directly affects cut quality - a practical benefit for anyone who needs repeatable results on routers and router tables.

Frequently Asked Questions
What CMT router bits and accessories is this bushing compatible with?
This bushing is specifically designed for use with the CMT 8/935-900 router bit and serves as the 3/4" collar for the CMT 835.990.11 accessory. Always verify compatibility with your specific CMT tooling configuration before installing.
What are the exact dimensions of this bushing?
The bushing has an outer diameter of 19.05mm (3/4") and a bore diameter of 12.7mm. These are the precise dimensions you should reference when confirming fitment with your router collet or bearing seat.
What material is this bushing made from?
The bushing is made from steel. This material resists deformation under the rotational forces present during routing, helping the bushing maintain its dimensional integrity and keep tooling properly centered over time.
Can this bushing be used on a router table as well as a handheld router?
Yes. This collet accessory is suitable for use with both routers and router tables wherever the compatible CMT tooling is being used and a bore reduction from the 19.05mm outer diameter to the 12.7mm bore is required.
