Our premium quality 1/4" shank Compression router bit is your best choice when working with patterns that mount on top of the finished product. The solid carbide construction provides a long-lasting sharp cut, while the compression design of the flutes guarantees a clean cut. An excellent router bit choice for creating mortises in flat panels. The top cutter geometry is designed for efficient plunge cuts, while the shank-mounted bearing keeps the cut exactly on target.
- 85-230B: 1/4" shank, 1/2" cutter diameter and 1-1/8" cutter height
Top-mounted bearing router bits offer several benefits:
- The bearing at the top of the bit simplifies the setup process, making it more straightforward for woodworkers, especially those who may be less experienced.
- This Infinity router bit can be used for multiple applications, including edge profiling, rabbeting, and dado cutting. The top-mounted bearing allows for greater flexibility in creating different profiles and cuts by adjusting the bit height. And the top-mounted bearing ensures a consistent depth of cut, particularly important when creating joints or when uniformity is critical.
- Top-mounted bearings are excellent for template and pattern routing. The bearing rides along the edge of the template and accurately creates an identical piece or an intricate design.
- Top-mounted bearing router bits are ideal for flush trimming operations.

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!
