CMT 837.501.11 3 Piece Cove Bit Set by CMT delivers three of the most commonly used carbide-tipped cove radii in a single convenient package, giving woodworkers and cabinetmakers everything they need to cut clean, consistent concave edge profiles. Whether you are shaping furniture edges, adding decorative detail to cabinet doors, or routing cove profiles in hardwood, softwood, or sheet goods, this set covers the full range of everyday cove routing tasks with a 1/2 in. shank designed for stability in both handheld routers and router tables.

Key Features

• 3-piece cove bit set with three commonly used radii (1/4 in., 3/8 in., and 1/2 in.) - covers the full range of standard cove profiles so you can work through multiple projects without swapping between individual bit purchases.
• Carbide-tipped (TCT) cutting edges - tungsten carbide stays sharper longer than high-speed steel, reducing the frequency of replacement and maintaining clean cuts through repeated use in hardwood, softwood, MDF, laminates, and more.
• 1/2 in. shank - the larger shank diameter reduces vibration and flex during routing, resulting in smoother cove profiles and greater accuracy on furniture edges and decorative trim work.
• 2-flute right-hand rotation design - dual cutting edges improve chip clearance and produce a cleaner, finer surface finish on concave edge profiles.
• CMT Orange Shield non-stick coating - prevents the bit from overheating, reduces pitch and resin buildup on cutting edges, and protects against corrosion to extend the working life of each bit in the set.
• SinterHIP industrial chrome carbide - carbide tips processed via Hot Isostatic Pressing (HIP) resist material failure under demanding cutting conditions, extending overall cutting life.
• Tri-Metal brazing (Silver-Copper-Silver) - the three-layer braze bond secures carbide tips against separation when routing harder wood species or composite materials, reducing the risk of failed welds.
• Anti-kickback body design - limits the depth of cut per pass and minimizes kickback risk, improving operator safety especially during freehand routing operations.
• Ball-bearing guide on each bit - the bearing rides against the workpiece edge to maintain consistent cove depth without the need for a fence, making guided edge profiling fast and repeatable.

Why This Product

• Three radius sizes in one set - instead of purchasing individual cove bits one at a time, this set immediately equips you with the 1/4 in., 3/8 in., and 1/2 in. radii that appear most often in furniture, cabinetry, and decorative woodworking projects.
• Carbide quality backed by advanced processing - the SinterHIP carbide and Tri-Metal brazing combination means the tips are less likely to chip or separate during demanding cuts in hardwood or composite sheet goods, offering a longer service life than standard carbide tips.
• Versatile machine compatibility - the 1/2 in. shank works with handheld routers, router tables, and CNC routing machines, so the same set serves across different shop setups without adapters or modification.
• Reduced maintenance between cuts - the CMT Orange Shield non-stick coating keeps pitch and resin from accumulating on the bit body and cutting edges, meaning less downtime spent cleaning and more time routing.
