Freud Straight Router Bit 12-158 3/4 Inch Double Flute (1/2 Inch Shank TiCo Carbide Perma-SHIELD 24000 RPM CNC Grooving Dadoes Plywood Joinery)

Freud 12-158 3/4 Inch Double Flute Straight Router Bit

The Freud 12-158 is a 3/4-inch overall cutting diameter double flute straight router bit engineered to execute deep grooving passes, dado joinery, plunge mortising, and edge profiling. Built with a heavy-duty 1/2-inch shank and an extended 2-inch carbide cutting height, this 2-cutter tool features end-relieved tip geometry for clean, burn-free plunge cuts. Tipped with TiCo™ Hi-Density Micrograin Carbide and protected by a thermal-resistant Perma-SHIELD® non-stick coating, it operates stably at rotational speeds up to 24,000 RPM across CNC machinery, router tables, or handheld routers in solid hardwoods, softwoods, plywood, and composites.

Best Used For:

• Full-Width 3/4-Inch Dado & Groove Milling: Cutting deep, 3/4-inch wide dado slots and joinery channels in cabinet side panels and shelving units.
• Plunge Pocketing & Deep Mortising: Plunging directly into timber stock to route clean interior cutouts, deep pockets, and hardware mortises.
• Straight Edge Profiling & Rabbeting: Trimming clean, square joint shoulders and edge profiles across thick hardwood planks and composite boards.

Key Performance & Safety Features

• TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges deliver exceptional durability and sharpness retention.
• End-Relieved Plunge Cut Tip: Precision-ground end face geometry allows smooth, chatter-free plunge entry into solid wood panels.
• Dual-Flute Precision Balance: Computer-balanced twin-cutter flutes equalize cutting forces to reduce tool chatter and produce smooth sidewalls.
• Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating guards against thermal friction, resin accumulation, and rust corrosion.
• Heavy-Duty 1/2-Inch Shank: Rigid 1/2-inch steel shank diameter minimizes tool flex, runout, and cutter vibration during high-speed routing.
• Extended 2-Inch Carbide Height: Generous cutting height capacity enables deep single-pass or multi-pass slotting across thick timber stock.

Technical Specifications

Pro-Tip: When routing deep 3/4-inch dadoes using a bit with an extended 2-inch cutting height, make pass depths equal to half the cutter diameter (3/8-inch deep per pass) to ensure proper chip evacuation and prevent wood burning.
