Product Description
The CMT Screw for Bearing - Torx T7 TSPTI M2.5 x 3 x 4.5mm (Diameter: 3mm) is a precision replacement fastener designed to secure bearings on CMT router bits and cutter heads. This small but critical component uses a Torx T7 drive interface, delivering reliable clamping force while resisting cam-out during installation and removal. Keeping a supply of these screws on hand ensures your CMT tooling stays properly assembled and ready for consistent, accurate cuts.
Key Features
- Torx T7 drive interface - reduces cam-out risk during tightening and loosening, protecting both the fastener and the driver tip for longer service life
- TSPTI screw type, M2.5 x 3 x 4.5mm dimensions - precisely sized to match the bearing retention specifications of compatible CMT router bits and cutter heads, ensuring a secure, play-free fit
- 3mm diameter - compact profile allows proper seating in tight bearing housings without interfering with surrounding tooling geometry
- CMT genuine replacement part (MPN: 990.070.00) - sourced directly from CMT to maintain original assembly tolerances and performance standards
Why This Product
- A stripped or missing bearing screw renders a router bit unusable - this genuine CMT replacement restores your tooling to full function without the need to replace the entire bit or cutter head
- The Torx T7 drive format provides a more positive engagement than slotted or Phillips fasteners, making bearing installation and removal more controlled in a workshop setting
- Exact M2.5 x 3 x 4.5mm sizing means this screw fits the specific bearing mounting configuration it was engineered for, avoiding the guesswork of sourcing a generic fastener that may not match thread pitch or head geometry
- As an active CMT replacement part, this screw is the correct OEM specification for maintaining the integrity of CMT router bits that use T7 Torx bearing screws
