Description

Master Precision Joinery and Spoilboard Surfacing with Freud’s Advanced Mortising Technology

The Freud 16-106 Mortising Router Bit is an essential tool for woodworkers and CNC enthusiasts who demand splinter-free, professional results. Specifically engineered to deliver deep, clean mortises in plywood, veneers, and solid woods, this bit is the go-to choice for recessing hinges and hardware or cutting perfectly flat-bottomed dadoes. Its large 1-1/4 inch diameter provides a wide cutting surface, making it exceptionally efficient for clearing material quickly while maintaining the structural integrity of your workpiece.

Beyond traditional joinery, the Freud 16-106 excels as a CNC spoilboard surfacing bit. The high-performance down shear design forces wood fibers downward during the cut, effectively eliminating top-surface splintering and leaving a glass-smooth finish. Designed with deep center gullets, this bit facilitates maximum material removal without the risk of chip loading or overheating. Whether you are using a hand-held router with a jig or a high-precision CNC machine, the Perma-SHIELD® coating reduces friction and pitch buildup, ensuring your tool stays cooler and sharper for longer production runs.

Key Features

  • Down Shear Design: Specially angled cutters push fibers down to ensure a clean, splinter-free top surface on every cut.
  • Deep Center Gullets: Optimized for rapid material evacuation, preventing chip loading and keeping the bit running smoothly.
  • Perma-SHIELD® Non-Stick Coating: Minimizes heat friction and protects the bit from resin or pitch buildup.
  • Versatile Application: Perfect for mortising hinges, cutting hardware recesses, and creating clean grooves or dadoes.
  • CNC Excellence: Ideal for surfacing spoilboards to ensure your CNC bed is perfectly flat and accurate for all projects.
  • Premium Carbide Construction: Features Freud’s high-density carbide for maximum cutting life and extreme durability.
  • Universal Compatibility: Designed for use on CNC machines, hand-held routers, and table-mounted portable routers.

Pro-Tip: When using this large-diameter bit for spoilboard surfacing, ensure your CNC router is perfectly square to the bed to avoid "tram lines" (small ridges between passes). For the cleanest finish, set your step-over at roughly 40-50% of the bit diameter and take shallow passes of no more than 0.01" to 0.02" at a time.
