CMT 856.501.11 Moulding Bit by CMT is a professional-grade carbide-tipped router bit designed for creating table edge profiles, hand rail profiles, and architectural moulding profiles in furniture and millwork applications. With a 1 7/8 in. cutting diameter, 1 1/8 in. cutting height, and a 1/2 in. shank, this right-hand rotation bit delivers clean, precise profiles in solid hardwood, softwood, MDF, plywood, laminates, melamine, and more. Built for router table use where large-diameter bits shine, the CMT 856.501.11 brings professional profile routing capability to woodworking shops and millwork operations alike.

Key Features

• Carbide-Tipped (HW) Cutting Edge - tungsten carbide tips stay sharp longer through dense hardwoods and composite sheet goods, reducing the frequency of bit replacement and keeping cuts clean pass after pass.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating during extended cuts, reduces pitch and resin buildup on the flutes, and protects against corrosion, extending overall tool life.
• SinterHIP Industrial Chrome Carbide - carbide processed via Hot Isostatic Pressing (HIP) eliminates internal voids that cause material failure, so the cutting edges hold up under repeated use in hard and abrasive materials.
• Tri-Metal Brazing (Silver-Copper-Silver) - the triple-layer braze bond between the carbide tip and the body withstands the stress of cutting harder wood and composites, dramatically reducing the risk of tip separation or weld failure.
• Anti-Kickback Design - controls depth of cut mechanically, minimizing kickback risk and improving operator safety on the router table.
• 2-Flute Right-Hand Rotation - dual cutting edges balance the load and produce a smoother moulding profile surface, reducing sanding time on finished pieces.
• 1/2 in. Shank - the full 1/2 in. shank provides maximum rigidity and reduced vibration compared to smaller shanks, which is especially important at the large 1 7/8 in. cutting diameter of this bit.
• Recommended for Use with 1800W Routers - pairing this bit with a sufficiently powerful router ensures consistent feed rates and clean profiles, avoiding bogging and burning caused by underpowered machines.

Why This Product

• The large 1 7/8 in. cutting diameter produces full moulding, table edge, and hand rail profiles in a single setup on the router table, eliminating the need for multiple smaller bits or multiple machine passes to achieve the same profile.
• The anti-kickback body design makes this bit significantly safer to use than standard profile bits at this diameter, which is critical when running large-diameter bits at reduced RPM on a router table with a fence.
• The combination of SinterHIP carbide and Tri-Metal Brazing means the cutting edges resist both chipping and tip loss in demanding materials like dense hardwoods and laminates, giving woodworkers and millwork shops more confidence over the life of the bit.
• The Orange Shield non-stick coating actively reduces pitch and resin accumulation, keeping the bit performing at its best between cleanings and extending the interval between sharpenings.
