Freud 16-106 Router Bit 1-1/4″ (Dia.) Spoilboard Surfacing & Mortising Bit

The Freud 16-106 1-1/4″ Spoilboard Surfacing & Mortising Router Bit is a reliable option for woodworkers, CNC operators, and tradespeople needing a clean-cut solution for both surface planing and mortising applications. Designed with a 1/4″ shank, this bit is compatible with palm routers, trim routers, and compact CNC setups, making it ideal for smaller routing platforms without compromising cut quality. Its 1-1/4″ diameter allows efficient surface cleanup while its precise geometry delivers smooth mortises, dadoes, and hinge pockets across a range of wood and engineered materials.

This dual-purpose bit features a down shear cutting design to help push fibers downward, reducing splintering on veneered plywood or hardwood surfaces. The deep center gullets efficiently clear chips from the cutting path, especially important when routing dados or flattening small slabs or spoilboards. Freud’s Perma-SHIELD® coating protects the bit from pitch buildup and heat, extending the tool’s life even in high-friction materials like MDF and composites.

Markets

• CNC Woodworkers Using Compact Machines Ideal for spoilboard surfacing or shallow dado cutting on CNCs with 1/4″ collets.
• Cabinetmakers Used to route hinge mortises and dadoes with smaller routers in confined spaces.
• Finish Carpenters Allows clean mortising for hardware and hardware insets on-site with trim routers.
• Educational Workshops A safe and effective option for teaching routing techniques using light-duty equipment.
• Small Furniture & Hobby Shops Useful for flattening smaller slabs or prepping boards on benchtop routers.
• Portable Router Users Compatible with handheld palm and trim routers used for on-the-go carpentry or installs.
• Sign Makers Efficient for prepping flat surfaces on MDF blanks in smaller CNC workflows.

For smaller routers or applications where a 1/2″ shank isn’t practical, the Freud 16-106 offers a precise alternative without sacrificing cut quality. Ideal for shops working with compact equipment, educational environments, or field applications where lighter tools are preferred. This bit is especially well-suited for light-duty CNCs and handheld routers where a 1/4″ collet is standard. The deep center gullets allow for efficient chip evacuation during cutting, while Freud’s Perma-SHIELD® non-stick coating reduces friction and protects against heat and pitch buildup.
