CMT Corner Beading Bit - 3/8" x 47/64", 3/16" Radius, 1/2" Shank by CMT is a professional-grade router bit engineered to cut clean, decorative corner bead profiles on solid wood, sheet goods, and composite panels. Whether you are adding traditional beaded edge details to furniture, cabinetry, or millwork, this carbide-tipped bit delivers precise, repeatable results in both handheld router and router table setups. Run the profile twice - once on each adjacent face - to form a complete corner bead, opening up a wide range of edge molding and decorative corner applications.

Key Features

• Carbide-Tipped Cutting Edges (HW Material) - hard-wearing carbide tips stay sharp longer through demanding cuts in hardwood, softwood, MDF, and composite materials, reducing downtime for bit changes.
• CMT Orange PTFE Non-Stick Coating - the signature orange coating prevents pitch and resin buildup on the bit body, reduces heat generation during cutting, and protects against corrosion, extending the working life of the bit.
• 2-Flute Design - dual cutting edges produce a balanced, smooth cut and help dissipate heat evenly, resulting in a cleaner bead profile with less tearout.
• Ball-Bearing Pilot Guide - the integrated bearing runs along the workpiece edge to control the depth of the bead profile accurately and consistently without marring the stock.
• 1/2" Shank - the larger 1/2" shank diameter provides greater rigidity and reduces vibration compared to smaller shanks, improving cut quality and router stability.
• Right-Hand Rotation - standard RH rotation is compatible with the vast majority of handheld routers, router tables, and CNC routing machines without any modification.
• 3/16" Radius Corner Bead Profile - produces a classically proportioned bead suitable for furniture edges, door frames, cabinet faces, and decorative molding work.
• Run-the-Bead-Twice Design - routing the same profile on two adjacent faces creates a complete, symmetrical corner bead, giving woodworkers flexibility to build full corner moldings from standard stock.

Why This Product

• The carbide-tipped cutting edges combined with the PTFE non-stick coating mean you spend less time cleaning the bit and more time cutting - a practical advantage when working through large batches of molding or cabinet parts.
• The 1/2" shank paired with a 2-flute geometry reduces chatter and vibration, giving you cleaner bead profiles on edge-sensitive materials like MDF and melamine where tearout is a common problem.
• The ball-bearing pilot removes the guesswork from depth setting - simply register the bearing against the workpiece edge and the 3/16" radius bead is cut at the correct depth every time, whether you are routing freehand or on a table.
• The run-twice design makes it possible to produce complete symmetrical corner beads without purchasing a dedicated full-corner profile bit, adding versatility to a single tool investment.
