Freud Spoilboard Surfacing & Mortising Bit – 1-1/4" Dia, 1/4" Shank, 18,000 RPM | CNC, Handheld & Table Routers

Engineered for clean, precise mortises

Freud's Spoilboard Surfacing & Mortising Bit is designed to deliver repeatable, splinter-free mortises across plywood, veneer, solid wood, and many composites. The down shear geometry pushes wood fibers downward during the cut, helping keep top surfaces flat and minimizing tear-out around hinge mortises, hardware pockets, and dado shoulders. This bit is built for flexibility, performing well on CNC routers, handheld units, and table-mounted machines alike, so you can move between projects without swapping tooling.

Efficient cutting and advanced chip management

The deep center gullets provide robust material removal per pass, reducing chip buildup and maintaining consistent cutting action even in denser woods. Paired with a Perma-SHIELD coating that reduces friction, heat, and pitch buildup, the bit sustains longer runs and steady performance across materials. It is rated up to 18,000 RPM, enabling optimized speed for your setup while preserving edge quality.

• Down shear geometry minimizes tear-out and delivers splinter-free mortises
• Deep center gullets promote efficient material removal and fewer clogs
• Perma-SHIELD coating improves wear resistance and heat management
• Top bearing options on many models suit routing jig setups
• 1-1/4 inch diameter and 1/4 inch shank fit a wide range of machines

Versatility across machines and applications

Whether you are mortising hinges or creating grooves and dadoes, this Freud bit helps you maintain alignment and edge quality. Its broad machine compatibility makes it suitable for CNC routers, handheld routers, palm routers, and table-mounted units, with some models offering top bearings to fit routing jigs.

• Suitable for hardwoods, softwoods, veneers, and most composites
• Top bearings support routing jig setups for added convenience
• Strong, durable construction designed for demanding shop use
• Reliable performance across high-speed passes when used within recommended limits

Note: Performance depends on technique and material. Use appropriate feed rates and start with light passes to dial in your setup. With its combination of precise geometry, durable coating, and broad compatibility, this Freud bit is a solid option for professional woodworkers and DIY enthusiasts tackling hinges, grooves, and dadoes at speed.
