Freud Straight Router Bit 12-116 3/8 Inch (1/2 Shank Double Flute TiCo Carbide 1 Inch Cut Depth Wood Composite Dado Grooving Plunge Cutter)

Freud 12-116 3/8 Inch Double Flute Straight Plunge Router Bit

The Freud 12-116 is a 3/8-inch cutting diameter double flute straight router bit engineered to execute precise dados, rabbets, mortises, and edge grooves in hardwoods, softwoods, plywood, and wood composites. Constructed with TiCo™ High-Density Carbide tips and Perma-SHIELD® non-stick coating fused to a rigid 1/2-inch steel shank, this precision wood-milling tool delivers smooth, chatter-free cuts at rotational speeds up to 24,000 RPM. Featuring a 1-inch carbide cutting height, 2-5/8-inch overall length, and relieved tip geometry for efficient vertical plunge cutting, it integrates directly with CNC machinery, table-mounted routers, and handheld power routers to maximize feed speed and slotting accuracy.

Best Used For:

• Precision Cabinetry Dado & Slot Routing: Milling exact 3/8-inch wide slot openings and joint channels in plywood panels, MDF, and solid lumber for drawer bottoms and cabinet backs.
• Mortise & Tenon Joinery Milling: Executing clean vertical plunge cuts and deep mortise pockets in hardwoods without surface tear-out or thermal burning.
• Composite Panel Edge Trimming: Slicing crisp, chip-free straight edges and rabbets on veneered plywood, particle board, and synthetic wood composites.

Key Performance & Safety Features

• TiCo™ High-Density Carbide Blades: Specialized micro-grain carbide formulation offers extreme resistance to heat oxidation and abrasion for extended edge sharpness.
• Perma-SHIELD® Non-Stick Coating: Thermal barrier coating reduces pitch buildup, friction, and heat accumulation during continuous milling passes.
• Relieved Tip Plunge Design: End-tooth geometry permits direct vertical plunging into workpiece faces for mortising and blind slot milling.
• Computer-Balanced Double Flute Geometry: Dual precision-ground cutting flutes balance rotational forces to eliminate tool vibration and sanding chatter.
• Heavy-Duty 1/2-Inch Steel Shank: Solid steel shank prevents deflection and tool slipping in high-torque router collets.
• Tri-Metal Brazing Bond: High-strength silver-copper-silver brazing absorbs shock impact to prevent carbide tip detachment during heavy passes.

Technical Specifications

Pro-Tip: When routing deep 3/8-inch dados in dense hardwoods, make multiple pass depths of no more than 1/4-inch per pass at 24,000 RPM to preserve carbide edge life and clear wood chips efficiently from the channel.
