CMT Super-Duty Shearing Flush Trim Bit, 3/4 in. Dia. x 2 in. Cutter, 1/2 in. Shank

CMT Super Duty Flush Trim Bit – 3/4 in. Dia. – 1/2 in. Shank

The CMT Super Duty Flush Trim Bit is engineered for fast, clean, and precise trimming with minimal chipping. Designed with a 3/4 in. cutting diameter, 1/2 in. shank, ball bearing guides, and a two-flute cutting design, this heavy-duty router bit delivers smooth, professional-quality results across a wide range of woodworking and routing applications.

A negative shear angle cutting edge and 19 mm cutting diameter distinguish CMT Super Duty Flush Trim Bits from standard flush trim bits. The cutting geometry is designed to produce a superior finish while helping reduce chipping and tear-out. The innovative two-flute construction incorporates a double-bearing design and down-shear cutting action for cleaner, smoother routing.

Designed for Smooth, Precise Flush Trimming

The down-shear configuration helps provide excellent cutting performance when trimming along or against the grain. The double-bearing design allows the bit to follow the workpiece accurately, making it especially useful for curved elements and demanding flush-trimming operations.

Unlike conventional routing methods that may require flipping or repositioning the tool to achieve the desired cutting direction, this CMT Super Duty Flush Trim Bit is designed to provide effective cutting performance without those additional steps. It is an excellent choice for professional woodworkers, cabinetmakers, and serious DIY enthusiasts who demand reliable results and a clean finished edge.

Key Features

• Two-flute cutting design provides efficient material removal and smooth cutting action.
• Negative shear angle helps minimize chipping and produce a superior finished surface.
• Double ball-bearing guides help the bit follow templates and workpiece edges accurately.
• Down-shear design promotes cleaner, smoother cuts on a variety of materials.
• Well suited for curved elements and routing along or against the grain.
• Designed for fast, controlled routing with excellent finishing results.

Professional-Grade CMT Construction

CMT manufactures its router bits using highly controlled production processes designed to achieve accuracy, balance, durability, and consistent cutting performance. Automated CNC production and specially trained operators help ensure that router bit shanks and bodies are manufactured to precise specifications.

• Turning, Milling and Cutting: Fully automated production equipment and CNC machining help ensure accurate, precisely balanced router bit shanks and bodies.
• Heat-Forged Steel Bodies: Large-diameter bits can require additional manufacturing steps, including heat forging the steel before precision machining. This process creates a radial grain orientation that contributes additional strength and durability.
• Precision Brazing: CMT's specialized computerized brazing equipment helps provide consistent carbide-to-steel bonds. A silver-copper-silver brazing sandwich creates a strong connection while providing a shock-absorbing effect that helps protect carbide tips during demanding cutting operations.
• Specially Formulated Carbide: CMT develops carbide formulations suited to different woodworking applications. Carbide characteristics can be selected to provide the hardness and impact resistance appropriate for everything from demanding laminate cutting to large-profile routing.
• Grinding and Sharpening: Final grinding and sharpening operations are performed with high precision using multi-axis CNC machinery. Precisely controlled bevels and cutting angles help produce consistent cutting performance and high-quality finishes.

Safety Tips

Routing laminate and other materials can generate dust and chips that may be hazardous to your health and safety. Always wear appropriate eye protection and a properly rated dust mask or respirator when operating a router.

Safety Precautions

• Never use a router bit that is damaged, cracked, bent, or excessively worn.
• Inspect the bit and bearings before use and replace damaged components as necessary.
• Always operate the router at the manufacturer's recommended speed and use the appropriate feed rate for the material and application.
• Do not force the router bit through the workpiece. Allow the cutting edges to remove material efficiently.
• Exercise particular care when making an initial cut, especially when working with smaller-diameter bits.
• For demanding cuts, remove material in multiple passes rather than attempting to make one excessively deep cut.
• Secure the workpiece properly and maintain firm control of the router throughout the operation.
