Product Description
CMT Moulding Bit - 1 3/8" Diameter x 33/64" Cutting Height, 5/16" Radius, 1/2" Shank is a professional-grade carbide-tipped router bit from CMT, designed to shape elegant classical moulding profiles on your router table or handheld router. With a 5/16" radius and 1 3/8" cutting diameter, this bit produces the kind of refined cove and moulding shapes traditionally used in furniture trim, cabinet moulding, and architectural millwork - profiles that are easy to install and create a polished, finished appearance. The 1/2" shank provides secure, stable seating in a wide range of compatible routers, and the right-hand rotation is standard for most router setups.
Key Features
- 1 3/8" Cutting Diameter with 5/16" Radius - produces full, consistent classical moulding profiles in a single pass, reducing setup time and the need for multiple bits
- 33/64" Cutting Height - provides sufficient depth of cut for complete moulding shaping on solid hardwoods and other common woodworking materials
- HW (Carbide-Tipped) Blade Material - tungsten carbide cutting edges retain sharpness through extended production runs, delivering clean profiles on hardwoods, softwoods, and composites
- 1/2" Shank - the larger shank diameter reduces vibration and deflection compared to smaller shanks, resulting in smoother cuts and more accurate profile reproduction
- 2-Flute Design - dual cutting edges improve balance during rotation and produce a finer surface finish, reducing the amount of sanding required after routing
- Right-Hand Rotation - compatible with standard router table and handheld router setups, no special tooling or configuration required
- 2 9/32" Total Length - compact overall length allows use in a wide variety of router collet configurations without sacrificing reach or stability
- Moulding Profile Versatility - after shaping the cove, the profile can be combined with inverted-profile bits to create different edges and complete a full custom moulding, unlike commercially available crown mouldings
Why This Product
- Custom moulding without the limitations of stock profiles - this bit produces shop-made mouldings that are easy to install and create a finished appearance, giving woodworkers a practical alternative to off-the-shelf crown moulding that rarely fits perfectly
- Designed to work as part of a moulding system - the profile can be extended and varied by combining it with inverted-profile router bits, allowing you to complete a full moulding rather than being locked into a single shape
- 1/2" shank for reduced vibration - the larger shank diameter is recommended for production routing and router table use, where chatter and deflection can negatively affect profile accuracy and surface quality
- 2-flute carbide construction for long cutting life - HW carbide tips hold an edge longer than high-speed steel on hardwoods and abrasive materials, making this bit a durable choice for furniture and cabinet shops

Frequently Asked Questions
Can this moulding bit be used with a handheld router or does it require a router table?
This bit is compatible with both handheld routers and router table setups. For moulding profiles, a router table is generally recommended because it provides better control and consistency over the full length of the workpiece, but the 1/2" shank makes it stable in either configuration.
What is the radius produced by this bit, and what kind of profile does it shape?
This bit produces a 5/16" radius cove profile with a 1 3/8" cutting diameter and 33/64" cutting height. The resulting shape is a classical moulding cove suitable for furniture trim, cabinet moulding, and architectural millwork applications.
Can this bit be combined with other bits to create a more complex moulding?
Yes. After shaping the cove profile with this bit, you can use router bits with inverted profiles to create different edges and complete the full moulding. This approach allows you to produce custom moulding profiles that go beyond what commercially available crown mouldings offer.
What materials can this moulding bit cut?
The HW carbide-tipped cutting edges are suitable for use on solid hardwoods, softwoods, and similar woodworking materials typically used in furniture, cabinetry, and architectural millwork projects.
