Start With a Great Bit, Then Add Dual Bearings. Excellent!
Our compression router bits are impressive performers to start with. The solid carbide construction provides a long-lasting sharp cut, while the compression design of the flutes guarantees a clean cut. By adding bearings both above and below the cutting flutes, you can work accurately with patterns mounted either above or below the workpiece.
Specs:
- 85-250, Cutter Diam. 1/2" | Cutter Height 1" | Shank 1/4"
Dual Bearing Router Bits Offer These Benefits:
- They can provide enhanced stability with the dual bearings riding on top and bottom templates. This extra support will reduce the chance of any wobbling or deviations.
- Dual bearings are particularly beneficial for template routing giving the quick option of running with the template either above, or below the workpieces. This opens up the option for working in a router table, or freehand.
- Top and bottom bearings allow for more versatility in creating edge profiles. They add greater flexibility in adjusting the depth and angle of cuts, leading to a broader range of design options.

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!

These router bits are a step up from standard pattern bits. Solid carbide compression router bits leave a very clean edge in complicated grains, and the dual-bearing design allows for pattern work with the pattern mounted either above or below the work piece.
Infinity's compression router bits provide quality tear-out-free cuts at the top and bottom of the cut, and are perfect for template work in woods with complicated grains and plywood. These dual-bearing solid C4 micrograin carbide bits make that cut even better, and they'll stay sharp longer! By adding bearings both above and below the cutting flutes, you can work accurately with patterns mounted either above or below the workpiece. We offer both a 1/4" and 1/2"-shank router bit to best meet your application, as well as a money-saving two-router-bit set.
The beauty of a dual-spiral compression router bit is the dual-flute design, with one facing up and the other facing down. These skewed cuts help support the wood fibers from both sides during the cutting process, preventing splintering and tear out.
The 85-940 is the beefiest of the two router bits. This ½” shank router bit has a ¾” diameter and a 1-½” cutter height. This router bit is able to easily cut plywood or solid wood (even cherry without burning). This is a solid router bit with great performance.
As mentioned, Cherry (prone to burning when cut) is no issue with the solid carbide compression router bits. Even when cutting across a void, the cut is clean and tearout free!
The 85-250 is the ¼” shank router bit. It has a ½” diameter cut with a 1” cutter height. It has All the features of the 85-940, but also includes the ability to follow patterns into tight corners because of it's smaller diameter.
This tricky corner was cut in two passes, both running from the outside into the corner to provide the best cut against the tricky grain. This was easily accomplished with the dual-bearing router bit by flipping the board over and raising the router bit! That’s a clean cut into a tricky corner. Make sure your template work is flawless with our Solid Carbide Compression Router Bits.Dav
