Achieve Flawless Splinter-Free Hinge Mortises with the Freud 1/2 Inch Mortising Router Bit

Create perfectly clean, flat-bottomed recesses for hinges and hardware with the Freud 16-100 1/2 Inch Mortising Bit. Unlike standard straight bits, this specialized cutter features a down-shear design that actively pushes wood fibers down as it cuts. This shearing action eliminates the surface splintering and "fuzz" often seen on plywood veneers and solid woods, ensuring that your hardware sits flush in a crisp, professional-grade mortise every time. Whether you are building cabinetry, installing doors, or creating intricate dados, this bit delivers the precision required for high-end joinery.

Engineered for efficiency and longevity, the 16-100 is equipped with deep center gullets that allow for maximum material removal without chip loading, keeping the bit cool during operation. The cutter is protected by Freud's signature Perma-SHIELD coating, which reduces friction and prevents the buildup of heat-generating pitch and resin. With a compact 1/2-inch cutting height and a 1/4-inch shank, this bit is perfectly balanced for use in CNC machines, hand-held routers, and table-mounted setups, making it a versatile essential for any woodworker's toolkit.

Key Features

  • Down-Shear Geometry: Pushes wood fibers down during the cut to eliminate surface splintering on veneers and solid wood.
  • Perma-SHIELD Coating: Non-stick coating reduces drag, prevents heating, and resists pitch buildup.
  • Deep Center Gullets: Optimized design clears chips rapidly to prevent clogging during material removal.
  • Hardware Installation: Specifically designed for creating clean, flat-bottom mortises for hinges and plates.
  • Versatile Compatibility: Safe for use in CNC, hand-held, and table-mounted routers.
  • Precision Ground: Computer-balanced to ensure vibration-free operation at high RPMs.

Pro-Tip: Because mortising bits like the 16-100 are designed with a short carbide height (1/2"), they are specialized for shallow hardware recesses. If you need to cut a deep dado or groove that exceeds 1/2" in depth, do not try to force the bit deeper than its carbide. Instead, switch to a standard double-flute straight bit with a longer cutting length to finish the depth.
