Solid Carbide Construction Outperforms Inferior Quality Competitors, Every Time!
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 on your top and bottom surfaces. By adding bearings both above and below the cutting flutes, you can work accurately with patterns mounted either above or below the workpiece.
Specs:
- 85-940, Cutter Diam. 3/4" | Cutter Height 1-1/2" | Shank 1/2"
- 85-941, Cutter Diam. 3/4" | Cutter Height 2-1/8" | Shank 1/2"
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.

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

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
