I wasn’t aware that I needed a certain set up to use on your in lay patterns. It made a world of difference.

I purchased the 6' Dadonator Jr expecting it to perform as described in Infinity Cutting Tools catalog. For the most part it performed as expected. Issues with the actual dado width produced by the blade were not what I was expecting, dado width was close to 1/64' oversized. Customer support experience was not a pleasant one. After many back and forth emails to convince Infinity that I was properly installing and using the blade they agreed to returning the blade for diagnosis at their facility.Three aggravating weeks later Infinity agreed that the blade was not within their specifications and offered to return the blade or give a refund. I chose the refund. During this entire process I got the distinct impression that Infinity Cutting Tools was convinced that their product was not the problem but rather it was something I was doing wrong ,in the end Infinity begrudgingly agreed that the fault was the Dado blade and not user error. Will I buy other Infinity Cutting tools in the future? Yes I most likely will. Nothing is perfect, mistakes happen and I try to be a gracious person.

I was wanting a dado blade that didn’t leave “bat ear” undecuts at the outside edges of the dado groove
