Snappy Counterbores for a One-Step Hole
Countersink bits are great when you're using wood screws with a cone-shaped head. However, if you're using lag screws, lag bolts, washer head screws, T-nuts & more, you need a countersunk hole with a flat bottom to properly seat the screw. That's where the Snappy SD-3 Counterbores are the perfect tool. The 3-flute counterbore creates a pilot hole and counterbores a flat bottomed hole in one step.
The drill bits are high speed steel and coated with Titanium Nitride (TiN) to increase wear resistance. Each counterbore has a 1/4" hex Power Bit shank to work with Snappy's Quick Change chuck.
Another great feature for woodworkers is the oversized set screw for the counterbore. Rather than fumbling around trying to tighten or loosen the screw, this oversized screw makes adjusting the counterbore a simple task. Sometimes it's the little things that make a big difference.
The counterbores are offered in five sizes, or buy the 5-Pc. set with canvas pouch and save!

- 1/8" x 3/8"
- 3/16" x 1/2"

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!
