Freud 12-135 19/32 Inch Double Flute Straight Router Bit

The Freud 12-135 is a 19/32-inch overall cutting diameter double flute straight router bit engineered to route wobble-free dado joints, shelf slots, and flat-bottom mortises in undersized nominal 5/8-inch plywood stock. Built with a rigid 1/2-inch shank, an Eclipse Grind center-relief tip, and a 1-1/4-inch carbide cutting height, this 2-cutter tool enables clean plunge entries into solid timber and composite sheet goods. Tipped with TiCo™ Hi-Density Micrograin Carbide and computer-balanced to eliminate cutter chatter, it operates at rotational speeds up to 16,000 RPM across CNC machinery, router tables, or handheld routers in solid hardwoods, softwoods, plywood, and wood composites.

Best Used For:

  • Undersized 5/8-Inch Plywood Dadoing: Milling precise 19/32-inch wide dado channels and cabinet shelf slots to match actual sheet thicknesses for gapless glue joints.
  • Plunge Pocketing & Hardware Mortising: Diving directly into veneered sheet stock to route clean interior cutouts, blind mortises, and hardware recesses.
  • Thick Panel Edge Trimming & Joinery: Trimming full-depth 1-1/4-inch timber edges and machining rabbet joints across hardwood panels without tearout.

Key Performance & Safety Features

  • Plywood-Matched 19/32-Inch Diameter: Precision-milled to match true 19/32-inch nominal 5/8-inch plywood sheets for tight, gapless mechanical joints.
  • Eclipse Grind Center-Relief Tip: Specialized plunge-cutting tip geometry permits efficient vertical drilling entry into solid wood panels and composite sheets.
  • Heavy-Duty 1/2-Inch Shank: Rigid 1/2-inch steel shank diameter minimizes tool flex, runout, and cutter vibration during heavy routing passes.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges resist abrasive glues and thermal wear.
  • Dual-Flute Precision Balance: Computer-balanced twin cutters distribute chip load evenly to produce smooth sidewalls and flat bottom cuts.
  • 16,000 RPM Maximum Speed Rating: Precision-engineered steel body maintains stable, chatter-free rotation across table-mounted, handheld, and CNC setups.
