Dado & Planer Router Bits for Grooves, Rabbets & Surface Work

Dado and planer router bits let you cut flat-bottomed grooves, wide rabbets, and skim surfaces directly at the router table or with a handheld router. Unlike a table-saw dado set, these bits work without a separate saw and are particularly useful for stopped grooves, angled dados, and surfacing operations on wide panels.

What to Look for in a Dado or Planer Bit

Quality dado and planer bits feature carbide cutting edges for durability on hardwoods and sheet goods, precision-ground bodies to prevent deflection, and anti-kickback geometry. Shank size — typically 1/2" for stability — matters when making wide, heavy cuts. This collection is actively curated, so selection evolves as new tooling is evaluated and approved to meet Infinity Tools' quality standards.

Frequently Asked Questions

What is a dado router bit used for?

A dado router bit cuts a flat-bottomed groove across the grain of a board, used for shelving, drawer bottoms, and panel joinery. Unlike a saw dado set, a dado bit works with a handheld router or router table for stopped grooves and angled cuts.

What is the difference between a dado bit and a planer bit?

A dado bit is optimized for cutting narrow, defined grooves and rabbets, while a planer bit has a wider cutting diameter and is designed to skim the surface of boards, leveling high spots or reducing thickness. Both produce flat-bottomed cuts.

What shank size should I choose for dado and planer bits?

A 1/2" shank is recommended for dado and planer bits because the larger diameter reduces deflection under the heavy lateral loads these bits generate. Use 1/4" shank bits only for light-duty work and smaller routers.

Can I cut dados with a router instead of a table saw?

Yes. A router with a dado bit and a straightedge guide or router table fence produces clean, flat-bottomed grooves. This approach is particularly useful for stopped dados and for sheet goods that are awkward to maneuver across a table saw.

Where can I find other groove-cutting options at Infinity Tools?

For table-saw dado cutting, see our stacked dado and flat top saw blades. For general router bit options, the drill and router bits collection covers a broad range of profiles.

Are dado planer bits suitable for cutting plywood?

Yes. Carbide-tipped dado and planer bits handle plywood and MDF effectively. Use a sharp bit and take multiple shallow passes to minimize tear-out on plywood face veneers, especially when cutting cross-grain.

How fast should I run a planer bit?

Always follow the router bit manufacturer's recommended RPM range, which decreases as bit diameter increases. Larger planer bits require lower speeds to stay within safe surface-footage limits. Consult our learning blog for guidance on router speeds and feed rates.

Does Infinity Tools guarantee the quality of its router bits?

Yes. Every router bit sold by Infinity Tools is backed by our quality guarantee. If a product does not meet your expectations, contact our team for support.

What are the shipping options for router bits?

Infinity Tools ships router bits throughout the US. Review current rates, delivery windows, and free-shipping thresholds on our shipping policies page.

How can I get help selecting the right dado or planer bit for my project?
