Product Description
CMT Wedge for Cutter Heads - 38 x 15 x 16mm by CMT is a precision-machined replacement wedge designed to secure profiled knives within compatible cutter heads and router bit bodies. Proper knife retention is the foundation of safe, accurate woodworking, and this wedge provides the clamping force needed to keep cutting inserts locked firmly in place during operation. Whether you are maintaining a cutter head assembly used for cabinet door profiling, joinery work, or raised panel routing, having the correct wedge on hand keeps your tooling system running at full capacity without unnecessary downtime.
Key Features
- Wedge for Cutter Heads and Router Bits with Knives - designed specifically to clamp and retain profiled knife inserts within cutter head and router bit bodies, ensuring the cutting edge stays locked securely during high-speed operation and reduces the risk of knife movement that could compromise cut quality or operator safety.
- 38mm Diameter - sized to match 38mm cutter head bodies precisely, so the wedge fits without play or slop and applies even clamping pressure across the full face of the knife insert.
- 15mm Cutting Height - supports knife inserts up to 15mm tall, making this wedge compatible with a range of standard profiled knife geometries used in cabinet and joinery cutter head sets.
- 16mm Total Length - the compact 16mm body length allows the wedge to seat fully within the cutter head slot, maintaining the correct balance and geometry of the assembled tooling system.
Why This Product
- A worn or lost wedge makes an otherwise functional cutter head unusable - this direct replacement restores full cutter head operation without requiring replacement of the entire tool body or knife set.
- The precise 38 x 15 x 16mm dimensions mean the wedge is engineered to fit its corresponding cutter head slot exactly, so knife retention is consistent and repeatable every time the cutter head is reassembled after a knife change.
- Keeping a spare wedge on hand eliminates production delays caused by a damaged clamping component - a small part with an outsized impact on workflow continuity in cabinet shops and joinery operations.
- Sourcing this wedge directly by CMT part number ensures compatibility within the CMT cutter head system, avoiding the fitment uncertainty that comes with generic or aftermarket clamping hardware.

Frequently Asked Questions
What does this wedge do inside a cutter head?
The wedge acts as the clamping element that presses against the profiled knife insert inside the cutter head body slot. When tightened, it locks the knife firmly in position so it cannot shift during cutting. Without a properly seated wedge, the knife insert cannot be held securely, making the cutter head unsafe and non-functional.
How do I know if this wedge fits my cutter head?
This wedge is sized at 38mm diameter, 15mm cutting height, and 16mm total length. It is intended for use with CMT cutter heads and router bits with knives that require a wedge of these exact dimensions. Cross-reference your cutter head model against these measurements to confirm compatibility before installation.
When should I replace the wedge on my cutter head?
The wedge should be inspected whenever you perform a knife change. Replace it if you notice visible deformation, cracking, thread damage, or if the wedge no longer applies firm, even clamping pressure against the knife insert. A compromised wedge affects both cut accuracy and safe tool operation.
Can this wedge be used with router bits as well as cutter heads?
Yes. According to the product data, this CMT wedge is designed for use with both cutter heads and router bits that use replaceable knife inserts. Always verify that the dimensional specifications - 38mm diameter, 15mm cutting height, and 16mm total length - match the requirements of your specific router bit or cutter head body.
