Product Description
The CMT Moulding System 1-1/4" x 29/32" Profile A is a precision-crafted router bit designed to give woodworkers the freedom to create elaborate, custom moulding profiles that go far beyond what standard lumber shop selections offer. Built with a 1/2" shank and a right-hand rotation, this 2-flute carbide-tipped bit is engineered for furniture making, architectural millwork, and decorative trim work where creative profile flexibility is essential. By combining two or more passes with compatible bits from the CMT Moulding System, you can produce dozens of unique profiles from heavy stock - refining each piece to its desired final shape using a router fence for precision guidance.
Key Features
- CMT Orange Shield Non-Stick Coating - prevents the bit from heating up during extended cuts, reduces pitch and resin buildup on the cutting edges, protects against corrosion, and extends overall tool life so you spend more time routing and less time cleaning or replacing bits.
- SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) eliminates internal material voids, prevents material failure under load, and significantly extends cutting life for long production runs and demanding hardwood applications.
- Tri-Metal Brazing (Silver-Copper-Silver) - a three-layer brazing system bonds the carbide tip more securely to the body, protecting against tip separation when cutting harder wood or composite materials and reducing the chance of failed welds that could compromise safety or finish quality.
- Anti-Kickback Design - controls the maximum depth of cut on each pass, minimizing kickback risk and making this bit safer to operate on a router table or with a handheld router, especially when profiling dense hardwoods.
- Profile A - Multi-Pass System Design - this bit is part of a coordinated moulding system, meaning it is engineered to work alongside other CMT profiles so you can combine passes to produce dozens of elaborate, custom moulding shapes that cannot be achieved with a single-pass bit.
- 2-Flute (HW) Carbide Construction - two cutting edges deliver balanced cutting forces and smooth surface finishes on solid hardwood, softwood, plywood, MDF, and composite panel materials.
- 1/2" Shank Diameter - the larger shank provides greater rigidity and reduced vibration compared to 1/4" shank bits, resulting in cleaner profiles and improved bit stability during router table operation.
- Right-Hand Rotation - standard RH rotation is compatible with the vast majority of routers and router tables, requiring no special setup or adapters.
Why This Product
- If off-the-shelf moulding profiles from lumber suppliers do not meet your design requirements, the CMT Moulding System lets you mill profiles directly from heavy stock and refine them to the exact shape you need - giving furniture makers and finish carpenters true creative control over every moulding detail.
- The multi-pass system approach means a single bit like this Profile A can participate in dozens of different finished profile combinations when used with other bits in the CMT Moulding System, multiplying its practical value far beyond a single-purpose profile bit.
- The SinterHIP carbide and Tri-Metal Brazing work together to maintain sharp, secure cutting edges through demanding hardwood and composite cuts - reducing the frequency of bit changes and keeping production on schedule.
- The Anti-Kickback body design and 1/2" shank construction make this bit a controlled, stable choice for router table use with a fence, where profile accuracy and operator safety both depend on consistent, repeatable depth of cut.

Frequently Asked Questions
What is the CMT Moulding System and how does Profile A fit into it?
The CMT Moulding System is a coordinated family of router bits designed to be used in combination with one another across multiple passes. Profile A is one of the profiles in this system. By combining two or more passes with different system bits, you can produce dozens of elaborate, custom moulding shapes that would not be achievable with a single-profile bit alone. Profiles are milled from heavy stock and then refined to the desired final shape using these bits with a fence.
Do I need to use a fence with this bit?
Yes - CMT specifies that these moulding system bits should be used with a fence. The fence provides the guidance and control needed to produce accurate, repeatable profiles, especially when making multiple passes to build up a complex moulding shape from heavy stock.
What router shank size does this bit require?
This bit has a 1/2" shank, which is the larger standard shank size. It requires a router or router table collet sized for 1/2" shanks. The larger shank diameter provides greater rigidity and stability during profiling cuts compared to smaller shank options.
What materials can this moulding bit cut?
This bit is constructed with HW (carbide-tipped) cutting edges and a SinterHIP Industrial Chrome Carbide formulation, making it suitable for solid hardwood, softwood, and composite panel materials commonly used in furniture and architectural millwork applications. The Tri-Metal Brazing further supports reliable performance in harder wood and composite cuts.
