Product Description
CMT Wedge for Insert Knives - 25/64" x 15/32" x 1/2" is a precision-machined replacement wedge designed to securely retain insert knives in CMT router bit bodies and cutter heads. Engineered to exact dimensional tolerances, this small but critical component ensures that knives remain firmly locked in place during operation, maintaining cutting accuracy and operator safety. Compatible with CMT router bits and cutter heads that accept 10mm (25/64"), 12mm (15/32"), and 12.7mm (1/2") knife diameters, this wedge is an essential spare part for woodworking professionals who rely on replaceable-knife tooling systems.
Key Features
- Designed for router bits and cutter heads accepting knife diameters of 10mm (25/64"), 12mm (15/32"), and 12.7mm (1/2") - provides broad compatibility across multiple CMT insert tooling configurations so one part covers several setups
- Diameter of 28.2mm - ensures proper fit within the router bit body pocket, preventing knife movement or chatter during cutting passes
- Cutting height of 4.3mm - delivers the correct clamping geometry so the wedge contacts and holds the knife insert at the right angle for reliable, repeatable performance
- Total length of 4mm - compact profile fits precisely within the knife slot without interfering with adjacent components, making installation straightforward
- Compatible with CMT series 651, 692, 693, and 695 cutter heads - supports a range of professional cutter head platforms so replacement is quick and consistent
Why This Product
- Replacing a worn or damaged wedge restores secure knife retention in CMT cutter heads and router bits, bringing tooling performance back to original specifications without requiring a full bit replacement
- Precise dimensional tolerances across all three knife diameter sizes (25/64", 15/32", and 1/2") mean the wedge seats correctly the first time, reducing setup time and minimizing the risk of knife slippage
- Coverage across CMT series 651, 692, 693, and 695 cutter heads means a single replacement part addresses maintenance needs for multiple tools in a professional shop environment
- Sourcing a genuine CMT replacement wedge maintains the dimensional integrity of the original tooling system, helping ensure that cutting quality and safety margins are preserved over the tool's service life
