Product Description
CMT Screw for Bearing - Torx T25 TSPTI M5 x 5 x 8mm, 9mm Diameter is a precision replacement fastener from CMT, engineered specifically for securing bearings on CMT cutter heads and router bits. This Torx-drive screw delivers a reliable, tool-positive connection that reduces the risk of cam-out during installation or removal, keeping your cutting tools properly assembled and performing at their best.
Key Features
- Torx T25 drive type - provides a six-lobe engagement that distributes torque more evenly than Phillips or hex drives, reducing fastener damage during tightening
- TSPTI designation - identifies this as the correct CMT-spec bearing screw, ensuring proper fit and function with compatible cutter heads and router bits
- M5 x 5 x 8mm thread and length specification - sized precisely for bearing retention applications, eliminating guesswork when sourcing a replacement
- 9mm head diameter - provides adequate clamping surface area on the bearing seat without interfering with surrounding components
- Part of CMT's 990 Torx screw series - designed and sourced to match original equipment tolerances so your tooling performs as intended after servicing
Why This Product
- Keeping a replacement bearing screw on hand means a lost or damaged fastener does not sideline an entire cutter head or router bit - restore your tooling to service quickly with the correct CMT-spec part
- The Torx T25 interface requires a matching driver, which helps prevent accidental loosening compared to fastener types that can be engaged by multiple tool sizes
- Matching the exact M5 x 5 x 8mm dimensions and 9mm head diameter to the original CMT specification means the bearing is held to the correct clamp load - critical for safe, accurate cutting performance
- Sourcing a genuine CMT part number (990.093.00) eliminates compatibility uncertainty that can arise when substituting generic hardware for precision tooling fasteners
