Freud 77-624 1/2 Inch Three Flute Mortise Compression Spiral Router Bit with 1/2 Inch Shank Solid Carbide Black I.C.E. Coating Melamine and Plywood

Achieve Industrial-Grade precision and Chip-Free Finishes on Double-Sided Materials

The Freud 77-624 1/2" Mortise Compression Spiral Bit is a high-performance solution engineered for woodworkers and CNC operators who demand flawless results when routing delicate, double-sided materials. Unlike standard compression bits, this mortise-specific design features a shorter up-shear length, making it the premier choice for milling grooves, mortises, and through-cuts in materials where surface integrity is critical. By combining up-cut and down-cut action, this bit compresses the fibers of the material toward the center, ensuring a glass-smooth, splinter-free finish on both the top and bottom surfaces of melamine, veneered plywood, and laminates.

Constructed from Freud Premier Solid Carbide and enhanced with TiCo™ High-Density Carbide, the 77-624 provides 2X the cutting life and performance of standard uncoated bits. To further extend its service life, it features Freud’s proprietary Black I.C.E. (Industrial Cooling Element) coating, which maintains a cool cutting edge and facilitates superior chip evacuation to prevent burning and resin buildup. Optimized for high-speed use in CNC machines, handheld routers, and table-mounted setups, this three-flute bit allows for faster feed rates and a superior quality finish in hardwoods, softwoods, and composites.

Specifications

Pro-Tip: To ensure a clean finish on both the top and bottom of your workpiece, make sure your initial pass is deep enough to allow the down-shear portion of the compression bit to fully engage the top surface of the material. A pass deeper than the 1/2" upcut length is required to engage the "compression" action that prevents surface chipping on melamine and veneers.
