CMT Moulding System Router Bit - 1 1/4" Diameter x 3/4" Cutting Height, Profile B, 1/2" Shank is a professional-grade carbide-tipped router bit engineered for woodworkers who demand more than off-the-shelf moulding profiles. Part of the CMT Moulding System, this 2-flute bit gives craftspeople the freedom to create dozens of elaborate custom profiles by combining two or more passes, making it a versatile tool for furniture making, architectural millwork, hand rail work, and decorative trim. Use it with a fence at the router table to mill profiles from heavy stock, then refine to the exact shape your project requires.

Key Features

• CMT Orange Shield Non-Stick Coating - prevents the bit from heating up during extended cuts, reduces pitch and resin buildup, protects against corrosion, and extends overall tool life so you get more mileage between bit changes.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) prevents material failure under stress and extends cutting life, meaning fewer interruptions and more consistent edge quality over time.
• Tri-Metal Brazing (Silver-Copper-Silver) - a three-layer brazing system protects the carbide tip when cutting harder wood or composite materials and significantly reduces the chance of weld failure, keeping the cutting edge securely bonded even in demanding applications.
• Anti-Kickback Design - controls depth of cut and minimizes kickback risk, improving safety and accuracy during each pass through the workpiece.
• Profile B Configuration - a defined, repeatable profile shape that can be combined with other CMT Moulding System bits across multiple passes to produce dozens of distinct moulding profiles without purchasing single-purpose bits.
• Right-Hand (RH) Rotation - matches the standard rotation direction of handheld routers, router tables, and CNC routing machines, ensuring straightforward setup and compatibility.
• 2-Flute (2-Tooth) Geometry - two cutting edges deliver balanced material removal and a smooth surface finish on solid hardwood, softwood, MDF, plywood, chipboard, laminates, melamine, and plastic.
• 1/2" Shank Diameter - the larger shank provides greater rigidity and reduces vibration compared to smaller shank sizes, translating to cleaner, more accurate profiles with less chatter.

Why This Product

• The CMT Moulding System approach lets you avoid the limitations of stock lumber-yard moulding - by combining Profile B with other passes or other bits in the system, you can produce dozens of custom profiles from a single setup, making this bit a long-term investment rather than a one-profile tool.
• The 3/4" cutting height and 1 1/4" diameter are sized for working profiles from heavy stock, giving you enough material to refine the shape in follow-up passes - ideal for furniture components, architectural trim, and hand rail profiles that require precise final dimensions.
• Hardwood-rated carbide with Tri-Metal Brazing and SinterHIP processing means this bit handles dense solid hardwoods and composite sheet goods alike, reducing the need to switch tools when your material changes mid-project.
• The anti-kickback design and right-hand rotation make this bit compatible with standard router table fence setups, supporting safer, more controlled routing in a workshop environment where repeat passes are common.
