Create Flawless, Splinter-Free Hinge Mortises with the Freud 5/8 Inch Down-Shear Router Bit

Eliminate surface defects and achieve professional-grade joinery with the Freud 16-102 5/8 Inch Mortising Bit. Designed specifically for discerning woodworkers, this bit utilizes a unique "down-shear" geometry. Unlike standard straight bits that can lift wood fibers and cause unsightly chipping on the surface, the 16-102 actively pushes fibers down as it cuts. This shearing action guarantees razor-sharp edges and splinter-free finishes, making it the perfect tool for routing shallow recesses in expensive plywood, delicate veneers, and solid hardwoods for hinges, locksets, and hardware plates.

Beyond its precision, this bit is built for performance. It features a wider 5/8-inch cutting diameter, allowing for efficient clearing of material in fewer passes. The cutter is engineered with deep center gullets to maximize chip removal, preventing the bit from clogging or overheating even during repetitive cuts. Protected by Freud's industrial Perma-SHIELD coating, the tool resists pitch buildup and corrosion, ensuring long-lasting durability. With a standard 1/4-inch shank, it is compatible with a wide range of CNC machines, hand-held trim routers, and table-mounted setups.

Key Features

  • Down-Shear Geometry: Pushes wood fibers down to eliminate surface splintering, essential for veneers and laminates.
  • Perma-SHIELD Coating: Non-stick red coating reduces friction, prevents heat buildup, and resists pitch.
  • Deep Center Gullets: Engineered to clear chips rapidly, preventing clogging and extending tool life.
  • 5/8 Inch Diameter: Wider profile clears material quickly for hardware installation and wide dados.
  • Splinter-Free Mortising: Specifically designed to create clean, flat-bottomed recesses for hinges and plates.
  • Versatile Compatibility: Balanced for safe use in CNC, hand-held, and table-mounted routers.

Pro-Tip: The 16-102 features a relatively short carbide height of 1/2". This is intentional for hinge mortising, but it limits the bit's depth capacity. Never attempt to cut a groove deeper than the 1/2" carbide length, as the steel shank will rub against the wood, causing friction burns and potentially ruining your workpiece.
