Product Description
The CMT 791.009.00 Bearing 5/8" - 1/4" is a precision replacement guide bearing designed to restore smooth, accurate performance to CMT router bits. Built from steel and engineered to precise dimensional tolerances, this router bit bearing serves as a reliable guide element for flush trim, pattern, rabbeting, and profile routing operations. Whether you are replacing a worn bearing on an existing bit or upgrading for more consistent self-guiding results, this bearing delivers the dimensional accuracy needed for clean, repeatable cuts along templates and workpiece edges.
Key Features
- Steel construction - provides the structural rigidity and durability needed to withstand the rotational forces and friction generated during router bit operation, extending the service life of your bits.
- 5/8" outer diameter with a 6.35mm bore - precise dimensional sizing ensures a proper fit on compatible CMT router bits, maintaining accurate edge-guiding contact with templates and workpieces.
- 5mm plate thickness - a compact profile that integrates cleanly into flush trim, pattern, and rabbeting bit configurations without interfering with cutting depth or bit geometry.
- Black shield with directional orientation - the black shield must be kept right side up to correspond with bearing rotation during reassembly, ensuring correct installation and smooth operation every time.
Why This Product
- A worn or seized guide bearing causes burning, chatter, and inaccurate cuts - replacing it with a correctly sized 5/8" bearing restores the self-guiding precision your flush trim or pattern bit was designed to deliver.
- The 6.35mm bore is matched to 1/4" shank router bit configurations, making this a direct-fit replacement that eliminates guesswork when servicing your existing CMT router bits.
- At 5mm plate thickness, this bearing fits within the tight geometry of profile, rabbeting, and pattern bits without requiring modifications to the bit body or cutting assembly.
- Sourcing a genuine CMT replacement bearing keeps your router bits performing to their original specifications, avoiding the inconsistencies that come with mismatched or generic bearing substitutes.
