Freud Straight Router Bit 04-103 3/16 Inch Double Flute (1/4 Inch Shank Black ICE TiCo Carbide 24000 RPM CNC Inlays Grooving Fine Joinery Plywood)

The Freud 04-103 is a 3/16-inch overall cutting diameter double flute straight router bit engineered to execute narrow inlay routing, fine groove jointing, CNC lettering, and plunge mortising. Built with a 1/4-inch shank and a 5/8-inch carbide cutting height, this 2-cutter tool features end-relieved tip geometry that enables smooth plunge entries into timber stock and composite panels. Tipped with TiCo™ Hi-Density Micrograin Carbide and coated with thermal-repelling Black I.C.E. (Industrial Cooling Element) coating, it operates at rotational 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:

• Fine Wood Inlay & Decorative Lettering: Routing delicate 3/16-inch channels and precise CNC lettering grooves in custom woodworking panels.
• Narrow Joinery & Spline Slotting: Cutting thin mortise pockets, drawer slots, and reinforcement spline channels in solid timber assemblies.
• Plunge Pocketing & Interior Cutouts: Diving vertically into sheet goods to route clean interior cutouts, blind grooves, and wiring channels.

Key Performance & Safety Features

• Black I.C.E. Thermal Coating: Industrial cooling element coating repels frictional heat buildup and prevents pitch accumulation to extend edge sharpness.
• TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt carbide tips maintain cutting edge hardness under continuous high-speed friction.
• End-Relieved Plunge Cut Tip: Precision-ground end face geometry allows smooth, vertical drilling entry for starting blind grooves and mortises.
• Dual-Flute Precision Balance: Computer-balanced twin cutters distribute chip loads evenly to eliminate cutter chatter 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.

Technical Specifications

Pro-Tip: When milling narrow 3/16-inch channels, make plunge passes in shallow depth increments equal to half the bit diameter (3/32-inch per pass) to maintain proper chip clearance and prevent bit deflection.
