Freud 04-128 15/32 Inch Double Flute Straight Router Bit
The Freud 04-128 is a 15/32-inch overall cutting diameter double flute straight router bit engineered to cut snug, wobble-free dado joints and grooves in undersized nominal 1/2-inch plywood. Built with a 1/4-inch shank and a 7/8-inch carbide cutting height, this 2-flute tool features end-relieved tip geometry that enables smooth plunge cuts into sheet goods and composite panels. Tipped with TiCo™ Hi-Density Micrograin Carbide and computer-balanced for chatter-free rotation, it operates at speeds up to 24,000 RPM across CNC machinery, router tables, or handheld routers in solid hardwoods, softwoods, plywood, and wood composites.
Best Used For:
- Undersized 1/2-Inch Plywood Dadoing: Milling precise 15/32-inch wide dado channels and shelf slots to match actual sheet thicknesses for gapless glue joints.
- Cabinet Carcass & Drawer Assembly: Routing clean joinery grooves, rabbets, and mortises in cabinet frames, drawer boxes, and shelving units.
- Plunge Pocketing & Interior Cutouts: Diving directly into timber panels to execute plunge routing for recessed hardware, pockets, and blind mortises.
Key Performance & Safety Features
- Plywood-Matched 15/32-Inch Diameter: Specially sized to match actual 15/32-inch nominal 1/2-inch plywood sheets for tight, rattle-free mechanical fits.
- TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt carbide tips maintain sharpness under heavy heat and thermal friction.
- End-Relieved Plunge Cut Tip: Precision-ground tip face permits vertical drilling entry for starting internal grooves, pockets, and mortises.
- Dual-Flute Precision Balance: Computer-balanced twin cutters distribute chip loads evenly to reduce vibration and produce smooth sidewalls.
- Optimized Hook & Shear Angles: Shear-angled cutting geometry slices through wood fibers cleanly to minimize chip tearout and burning.
- 24,000 RPM Maximum Speed Rating: Engineered to remain structurally balanced at high spindle speeds in table-mounted and CNC setups.
