Precision 1/2 Inch Shank 2 Inch Diameter Adjustable Stacked Slotting Router Bit Set

The Freud 61-102 Adjustable Stacked Slotting Router Bit Set functions as a multi-depth grooving cutter engineered to mill custom-width slots, tongue-and-groove joints, and spline channels in timber stock. Utilizing four stackable micro-grain TiCo titanium cobalt carbide slotting cutters and precision spacers, this 1/2-inch shank arbor system adjusts groove widths from 1/8 inch to 23/32 inch. Operating on handheld or table-mounted routers at speeds up to 16,000 RPM, the set includes three interchangeable steel pilot ball bearings that establish precise cutting depths of 1/4 inch, 3/8 inch, and 1/2 inch across hardwoods, softwoods, plywood, and composite materials.

Best Used For:

  • Tongue & Groove Joint Milling: Stacking slotting wing cutters with micro-shims to mill matching panel grooves and spline slots for custom cabinet assemblies.
  • Biscuit Joint & T-Molding Slotting: Cutting precise, burr-free perimeter channels in cabinet face frames and counter edges to seat joinery biscuits or flexible plastic edge trim.
  • Variable-Depth Drawer Bottom Grooving: Routing parallel bottom panel channels into drawer sides at 1/4-inch, 3/8-inch, or 1/2-inch depth settings without shifting router base stops.

Key Performance & Safety Features

  • Adjustable Stacking Slot Cutter Wings: Four individual 2-inch diameter carbide cutters combine to achieve precise slot widths from 1/8 inch to 23/32 inch.
  • Interchangeable Depth Pilot Bearings: Three included ball bearings establish 1/4-inch, 3/8-inch, and 1/2-inch cut depths with zero setup fence guessing.
  • TiCo Micro-Grain Carbide Flutes: Proprietary titanium cobalt carbide formulation maintains razor-sharp edges through abrasive hardwood and composite runs.
  • Perma-SHIELD Thermal Protection: Heat-resistant red fluoropolymer coating prevents pitch buildup, reduces cutting drag, and guards against corrosion.
  • Heavy-Duty 1/2-Inch Arbor Shaft: Precision-ground steel arbor eliminates cutter deflection during high-torque routing passes in handheld or table routers.

Pro-Tip: When stacking multiple slotting cutters on the arbor, stagger the cutting tips so the carbide teeth are offset from one another rather than lined up vertically. Staggering the teeth reduces initial motor drag, balances rotational force at 16,000 RPM, and eliminates chatter marks on wide groove walls.
