Freud 77-605 3/8 Inch Three Flute Mortise Compression Spiral Router Bit with 3/8 Inch Shank Solid Carbide Black I.C.E. Coating Melamine and Plywood

Achieve Flawless Chip-Free Finishes on Double-Sided Materials with Precision Mortise Compression Technology

The Freud 77-605 3/8" Mortise Compression Spiral Bit is a high-performance solution engineered for woodworkers who demand perfection 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 thin materials 5/8" thick or less. By combining up-cut and down-cut action, this bit compresses the fibers of the material toward the center, ensuring a splinter-free finish on both the top and bottom surfaces of melamine, veneered plywood, and laminates.

Built for industrial durability, the 77-605 is manufactured from Freud Premier Solid Carbide and enhanced with TiCo™ High-Density Carbide to provide 2X the cutting life and performance of standard uncoated bits. The bit is finished with 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 provides a faster feed rate and a smoother finish in hardwoods, softwoods, and composites.

Key Features

Specifications

Pro-Tip: To ensure a perfectly clean finish on both the top and bottom surfaces 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 1/4" upcut length is essential to activate the "compression" action that prevents surface chipping on delicate veneers and melamine.
