Plywood is usually thinner than the nominal measurements indicate. As a result, regular size bits usually don't cut a tight-fitting dado. Fortunately, undersized dado bits like these will help your joinery fit perfectly, resulting in stronger assemblies and nearly invisible joint lines. This set includes the three most common sizes of straight bits for undersized plywood: 23/32" for 3/4" plywood, 31/64" for 1/2" plywood, and 15/64" for 1/4" plywood.

Rockler Undersized Plywood Router Bit Set

(1) 23/32" Straight Bit for 3/4" plywood

(1) 31/64" Straight Bit for 1/2" plywood

(1) 15/64" Straight Bit for 1/4" plywood

Time saving and accurate.
I'm just learning to use my router. This is better than my dado blade and makes a cleaner cut.

Right on the money!
Undersized plywood fits the groove perfectly. Not loose, not too tight, but just right. Saves a lot of trial and error time.

need to make some dados, don't currently have a table saw with a dado blade.
Brian Saxe C on Aug 4, 2019
When I made my first plywood cabinets, I used a 3/4” straight router bit with my router table to make dado grooves, which had some play, complicating box assembly, and leaving visible gaps. This bit set will take my cabinet making to the professional level.
Joseph F on Aug 4, 2019
Making plywood furniture and these bits create correct sized channel/dados.
Ken on Jul 23, 2019
Building some closet units using Walnut Plywood. Need to make several dados for shelves, etc. These are much faster to use then setting up dado stacks and trying to get the right fit.
Norman S on Jul 15, 2019
I'm going to be using both 1/4" and 3/4" plywood in a project and this appears to be the best deal for helping make sure they will have a snug fit.
Michael W on Jul 9, 2019
I chosed these undersized router bits to avoid loose joints.

Denny M on Mar 29, 2019
Needed the flexibility of straight bits that can be used with typical plywood.
David R on Mar 24, 2019
It's in the name. 1/4 inch plywood is not 1/4 inch. Hoping this bit will provide a better fitting groove.
Tommy F on Mar 22, 2019

Plywood is always undersized. These speed up the process.

is the price for 4 unit router bit?
saiful on Sep 21, 2015
BEST ANSWER: This is a 3 piece set of router bits with 1/4" shanks.
Do you sell 1" straight router bits?
Tom G on Jul 1, 2017
BEST ANSWER: I don't think they sell a 1" straight router bit. You can make the cut with 2 passes. Cut one side with a 3/4 router bit then cut the other side with the same 3/4 router bit so you don't have to anymore adjustments. Just make a straight edge for your router and use it on both sides. Hope this help you.
Will these bits allow me to use the Festool MFK 700 to cut 6mm deep dadoes in 19mm thick plywood? The MFK 700 has stringent size requirements - cutting length can't be greater than 5/8" and a shank length not more than 1 13/16" - 1/4" collett (or 8 mm)
