Rockler Undersized Plywood Router Bit Set

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

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.

Only used the 3/4 so far but so good
I bought the set knowing I'd use them all eventually but so far only the 3/4 has been used. They come nice and sharp and cut to the right width for plywood.

It's in the name. 1/4 inch plywood is not 1/4 inch. Hoping this bit will provide a better fitting groove.

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)
