Product Description
CMT TCEI M2.5 x 6 x 8.5mm Screw for Bearing (D=4.5mm) is a precision replacement fastener from CMT, engineered specifically for bearing retention on router bits and cutter heads that use M2.5 TCEI socket screws. Whether you are maintaining a professional router bit set or restoring a cutter head to factory performance, having the correct bearing screw on hand means less downtime and a properly secured bearing every time. This small but critical component keeps bearing assemblies locked in place, ensuring safe and accurate operation during demanding routing and cutting tasks.
Key Features
- TCEI socket head drive type - the internal hex socket head provides a secure, cam-out-resistant grip during tightening, so you can apply consistent torque without stripping the fastener head
- M2.5 thread size - matches the precise thread specification required for CMT bearing retention applications, ensuring a flush, wobble-free fit that holds the bearing firmly in position
- 6mm thread length - provides adequate thread engagement within the cutter body to retain the bearing securely without bottoming out or over-penetrating
- 8.5mm overall length - the total screw length accounts for both the threaded shank and the head, making installation straightforward with no guesswork about fit
- 4.5mm head diameter - the compact head diameter keeps the screw low-profile relative to the bearing seat, avoiding interference with the workpiece or the bit's cutting geometry
- CMT replacement part (Class RPPJ) - sourced directly as a genuine CMT replacement component, so you can be confident it meets the same tolerances as the original hardware that shipped with your CMT tool
Why This Product
- A worn or missing bearing screw is one of the most common causes of bearing play in router bits - this genuine CMT replacement restores the original clamping spec without requiring a whole new bit assembly
- The M2.5 TCEI thread and head dimensions are matched precisely to CMT router bits and cutter heads that use this fastener standard, eliminating the uncertainty of sourcing a generic hardware-store substitute that may not fit correctly
- The 4.5mm head diameter combined with the compact overall length of 8.5mm means the screw seats properly in tight bearing pockets where a larger or longer fastener would interfere with the surrounding geometry
- Keeping a supply of these bearing screws on hand as a spare part is a straightforward way to extend the service life of CMT router bits, deferring the cost of full bit replacement when only the fastener has worn or been lost

Frequently Asked Questions
What does TCEI mean for this screw?
TCEI refers to the socket head cap screw style with an internal hex (Allen) drive. This drive type allows precise torque application in confined spaces, which is important when fastening a small bearing screw inside a router bit or cutter head body where access is limited.
How do I know if this screw fits my CMT router bit?
This screw is designed for CMT router bits and cutter heads that use an M2.5 TCEI bearing retention screw. Check your bit's existing fastener thread size and head style - if it calls for an M2.5 TCEI screw with a 6mm thread length and 4.5mm head diameter, this is the correct replacement part.
Can I use a generic M2.5 screw instead of this CMT part?
While M2.5 is a standard metric thread size, the combination of the 6mm thread length, 8.5mm overall length, and 4.5mm head diameter must all match the seat geometry in your specific CMT bit. Using a screw with incorrect head diameter or length risks improper bearing retention and potentially unsafe tool operation. This genuine CMT replacement part is dimensioned to match the original specification exactly.
What tool is needed to install this screw?
This TCEI screw requires an appropriately sized internal hex (Allen) key or hex bit driver. The M2.5 thread size corresponds to a small hex key - consult your CMT router bit documentation for the specific hex key size recommended for your bit model to avoid rounding the socket.
