Had purchased the non XL dadonator about one and a half years ago. The XL wasn't listed on the site. Purchased because it was Saw Stop compatible. It is not, but since I waited over a year to start the project I purchased it for. There was no help from Infinity Support. They did tell me they are using the dadonator on a Saw Stop for the last 3-4 years. But had no help from support to back the product. I tend to think that this has been a problem for Saw Stop owners for a while. Especially since Infinity came out with a new dadonator XL to address the issue. Your products are impressive. Your support is not.

Customer ServiceThanks for the feedback, Tom. Our team puts a lot of effort into serving and supporting our customers to the best of our ability. Both our 8" Dadonators work great on on Sawstop saws. We redesigned the Dadonator not because we had any issues with use on SawStop use, but to offer the a dado stack that uses less internal chippers. thus reducing the weight of the stack. If you are having a problem or just have additional questions please reach out our office hours are Monday – Friday, between 8:30 am and 5:00 pm ET. Just give us a call or send us an email to open a support ticket, and we’ll be happy to help!

Whether used in contemporary, or classic furniture, dovetail joinery is a highlight of quality woodworking.
Infinity Tools offers a large selection of dovetail bits designed with negative shear angle to provide ultra smooth cuts, and they’re available in all sizes and for all needs. But one thing that doesn’t change … is the general shape of the bit. The weakest point of all dovetail router bits is their neck. To get the longest life possible from this type of bit, we recommend pre-plowing the groove before cutting the dovetail slot.
Pre-plowing is the concept of using a straight bit (sized smaller than the diameter of the neck) to first cut a clearance channel. Start by finding the diameter of the neck of the dovetail bit using a caliper.
Then you locate an appropriate straight bit slightly under the diameter of the neck of the dovetail bit. Use that straight bit to set up the plowing cut.
You make a first pass with the straight bit to remove much of the waste. Remember don’t run this straight bit too fast. Let the bit cut.
The dovetail bit is then used to follow through that channel, but the stress on the bit is greatly reduced, leading to better dovetail cuts … and a longer life for your dovetail bits!
Follow this simple tip and you'll get the best performance from your dovetail router bits.
