10 Best Router Bits For Cutting Plywood in 2026

The four included bits match the true, slightly undersized thickness of modern plywood sheets. This precise sizing means you can rout dadoes and grooves for panels that actually fit tight without slop or force, which is the foundation of professional-looking cabinetry and furniture. For anyone working with sheet goods, this set solves the single most frustrating fit problem right out of the box. It’s a premium choice for woodworkers who value accuracy over a sprawling collection of single-purpose tools.

Designed for routing grooves in undersized plywood, this Freud set includes four bits matching true thicknesses from 1/4″ to 3/4″, which ensures tight-fitting joints for cabinetry and furniture. Its 1/4″ shank is compatible with both hand-held and table-mounted routers. The bits come in a wooden shadowbox case for safe storage and transport.

A 23/32-inch cutting diameter is the key here, designed to match the true thickness of standard 3/4-inch plywood. That means your dados and mortises will be snug right out of the gate, eliminating sloppy joints and saving you time on shimming or adjusting. This bit is for the woodworker who regularly builds cabinets or furniture from sheet goods and needs dead-on accuracy for strong, clean joinery. The micrograin carbide and Bosch’s heat-treating process are built for the long haul, promising to stay sharp through many linear feet of abrasive plywood glue lines.

This router bit is designed specifically for creating tight-fitting mortise joints in standard 3/4-inch plywood. Its undersized cutting diameter matches the actual thickness of that material, which means joints fit together without slop. While specialized for that single thickness, it lacks the versatility for other common plywood sizes. For projects using varying panel thicknesses, a set like the Freud 4 Piece Undersized Plywood Bit Set covers a wider range.

A 1/4-inch downcut spiral is the secret weapon for clean plywood dados and mortises. The downcut action pushes chips down into the cut, leaving the top face of your plywood tear-out free. That’s critical when you’re routing a slot for a shelf in a cabinet side. The special coating on the carbide also promises a longer-lasting edge, which means you can tackle more linear feet of MDF or oak ply before needing a replacement. This bit is built for the detail work where a pristine surface matters most.

Its 1-inch cutting length handles standard 3/4-inch material, but limits its use for deeper two-layer dados. For tasks requiring a specific 23/32-inch dimension, the Bosch Carbide-Tipped Plywood Mortising Router Bit is listed as an alternative. This SpeTool bit serves as a versatile choice for general grooves and slots in various woods, providing clean top edges without needing a separate finishing pass.

The relieved tip geometry on this bit is the key feature for anyone who needs to start a cut in the middle of a plywood sheet. It plunges in cleanly, reducing strain on your router and giving you a precise starting point for dados or mortises. The Freud TiCo carbide holds an edge through abrasive plywood glue layers, and the shear angles produce a finish that often needs little sanding. It’s a premium, single-purpose bit built for the workshop that demands reliability for repeated plunge work.

Its general-purpose design is the trade-off. For dedicated plywood joinery, such as routing grooves for undersized panels, a specialized four-bit set from Freud is more efficient. This Freud straight bit excels at the initial plunge and subsequent straight-line routing, but its 1-1/4 inch cutting length won’t handle thicker stock. Think of it as your go-to for starting clean cavities, not as a complete solution for all plywood dado tasks.

The EANOSIC bit is made of solid virgin carbide with a blue nano coating, which the manufacturer says provides up to 2.5X longer life than uncoated bits. This coating is intended to retain sharpness and lubricity under heat, a key factor for longevity in demanding woodworking. Its downcut spiral design is suited for use on plywood, oak, MDF, and hardwoods.

With a 1-inch cut length, this bit can handle many standard plywood and hardwood tasks. It is a specialized downcut spiral flush trim bit with a top bearing, designed for producing a flush edge rather than for general-purpose routing. According to the manufacturer, it fits CNC routers and any plunge routers with a 1/4-inch collet.

Three bits in the set are sized for 1/4-inch, 1/2-inch, and 3/4-inch plywood, letting you cut dados for standard cabinet and shelving projects directly. This specificity eliminates test cuts and shims for those common materials. Carbide cutting edges on a steel shank provide extended life and reduced vibration, which supports repeated, accurate cuts in demanding use.

Its application is quite specific. For a more versatile, case-included set that handles undersized plywood, Freud’s four-bit set is a direct alternative. The Whiteside set excels where precision for North American standard sheet goods is non-negotiable, but it doesn’t try to be a universal solution.

This three-bit set delivers exactly what you need for crisp dadoes and grooves in plywood. The 15/64, 31/64, and 23/32-inch diameters are the precise sizes for creating perfectly matching joints, a detail that saves you from sloppy, loose-fitting shelves or cabinet parts. The industrial carbide edges stay sharp, and the orange coating helps keep the bits clean. It’s a focused, no-fuss set for the woodworker who values accuracy in joinery over having a drawer full of rarely used sizes.

This three-piece set is specifically designed for making perfectly matching joints on plywood. Its 1/4-inch shank fits most common routers, and the bits are made from super-strength superior steel with a Non-Stick Orange Shield Coating. According to a test by Wood Magazine, CMT bits were rated the best overall in comparison to other brands.

Aoranto bundles four flush trim bits with cutting lengths from a quarter-inch up to an inch and a half, giving you a core set for template work across common material thicknesses. Their solid carbide is made from ultra-fine grain material with a high hardness rating, which the manufacturer states ensures a long-lasting cutting edge. This set establishes a ready toolkit for the repeated pattern routing of parts from laminate, melamine board, MDF, or wood.

These bits are specialized for flush trimming, excellent for profiling and duplication work. They won’t help you cut grooves or dados in plywood panels. For that specific task, you’d need a dedicated four-bit set from Freud. The Aoranto set excels at making multiple, identical parts from a master pattern, a common need in cabinet and furniture work where plywood is the primary material.

Its 23/32-inch cutting diameter matches undersized plywood, so dados fit accurately without slop. The two-flute, carbide-tipped design delivers smooth, flat-bottom cuts. A rigid 1/2-inch steel shank reduces vibration for clean results.

This is a single-purpose bit for one specific groove width. Buyers needing multiple dado sizes might consider Freud’s four-bit set. The Whiteside 1083A focuses solely on the 23/32-inch dimension.

This bit’s 31/64-inch cutting diameter creates dado grooves sized for the actual thickness of nominal 1/2-inch plywood, which prevents sloppy joints in cabinetry or bookshelves. Premium C3 micro-grain carbide and silver induction brazing are used for a sharper, longer-lasting edge. The 1/4-inch shank and compact profile fit common handheld routers as well as table-mounted or CNC setups.

This bit does one job exceptionally well, but just that one job. If your work involves plywood of various thicknesses, Freud’s four-bit set offers more flexibility. Furthermore, the 1/4-inch shank is perfectly adequate for plywood dados. For deep, heavy cuts in solid lumber, a 1/2-inch shank bit provides more rigidity and reduces vibration.
