Porter-Cable 7005012 Oldham 7-in Adjustable Dado Blade

 (5 customer reviews)

I don't do alot of wood working, but I occassionally have need to make wide cuts or grooves in wood or Azek trim board. My Skil table saw has a relatively short arbor, which won't safely accomodate most stacked dados, which is why I turned to the Oldham wobble dado. I wasn't sure how well this blade would work, but it proved to be perfect for my need. It fits the short arbor of my Skil table saw, is easily adjusted w/ a Phillips screwdriver, and makes accurate and consistent dado cuts. It's also less expensive than a stacked dado. This wobble dado by Oldham suits my occasional need and I'm pleased with it.

Great idea but falls short on execution..
The arbor pieces are difficult to orient on the blade, is too wide for most table saw's (especially the direct drive ones).
Suggest a small amount of glue on the 2 inner parts that touch the blade... once mounted it takes a bit of adjusting to get it just right..hard too line up the fence due to the wobble feature,, what tooth is the closest to the fence?... makes pretty good cuts.. ended up buying a much better table saw, and use my stacked dado instead..

Before you purchase measure your arbor length is long enough, I think the minimum on the package state's 1 3/8...

You will never get a flat smooth dado from a wobble blade! This is a quick and dirty way to cut dados if you just need a groove. It works great for rough construction purpose.
If you want clean smooth dados then spend the money and get a stacked dado set, otherwise expect to get the rabbit plane out or a sanding block and add some elbow grease.

This product does what you expect for the price you pay...
