The CMT 806.227.11 3-Flute Super-Duty Flush Trim Bit is a precision routing tool engineered for demanding woodworking applications where a clean, flush cut is essential. With a 1/2 in. cutting diameter, 1 in. cutting height, and a compact 1/4 in. shank, this right-hand rotation bit is purpose-built for template routing, laminate trimming, and pattern copying. Its three-flute carbide configuration delivers smoother surface finishes and faster chip evacuation compared to standard two-flute designs, making it a go-to choice for both shop professionals and serious hobbyists working with hardwood, plywood, laminates, and composite materials.

Key Features

• 3-Flute Carbide Cutting Edge - three flutes produce more cuts per revolution than a standard two-flute bit, resulting in a finer finished surface and reduced tearout on laminates and hardwoods.
• CMT Orange Shield Non-Stick Coating - prevents the bit from overheating during extended use, reduces pitch and resin buildup on the carbide, guards against corrosion, and extends overall tool life between sharpenings.
• SinterHIP Industrial Chrome Carbide - carbide tips processed via Hot Isostatic Pressing (HIP) achieve a denser, more uniform grain structure that resists material failure and delivers longer cutting life on abrasive materials like MDF and melamine.
• Tri-Metal Brazing (Silver-Copper-Silver) - a three-layer brazing bond secures the carbide tip with superior strength when routing harder wood or composites, dramatically reducing the chance of tip separation or failed welds under heavy loads.
• Anti-Kick Design - engineered geometry helps prevent the bit from grabbing or self-feeding during the cut, promoting safer, more controlled routing passes.
• 1/2 in. Diameter x 1 in. Cutting Height - the cutting geometry is optimized for through mortises, full-depth template passes, and precision flush trimming in a single controlled pass.
• Right-Hand (RH) Rotation - compatible with standard handheld routers, router tables, and CNC routing machines without any special tooling considerations.
• HW (Hardmetal / Carbide) Material - tungsten carbide construction maintains a sharp cutting edge longer than high-speed steel, keeping cuts accurate across extended production runs.

Why This Product

• The super-duty three-flute design is specifically built for precision work on laminates and quick template routing where surface finish quality matters - fewer passes means less sanding and faster project completion.
• The 1 in. cutting height combined with the 1/2 in. diameter makes this bit effective for through mortises and full-profile template work, reducing the need to reposition or make multiple shallow passes.
• CMT Orange Shield coating paired with SinterHIP carbide directly addresses the two most common causes of premature bit failure - heat damage and carbide wear - extending the usable life of the bit across demanding production environments.
• The 1/4 in. shank size offers broad compatibility with lightweight handheld routers and compact router tables, giving users flexibility to use this flush trim bit across a wide range of machines already in their shop.
