Infinity Tools Insert-Pro 嵌槽成型刀具，1-1/4英吋孔徑

The two-inch carbide knives make rabbeting a total breeze—edges come out glass-smooth with zero tear-out even on figured maple. I've run maybe thirty linear feet so far and the four-sided cutters on top and bottom are still slicing like they're fresh out of the box.

Installed it on my shaper this morning and ran some white oak—the 2" carbide knives left a finish so smooth I didn’t even need to sand the rabbets. That four-sided cutter setup on both top and bottom really earns its keep when you’re working tricky grain.

I was skeptical about the four-sided cutters on top and bottom, but they really do slice the wood surface cleanly, leaving me with almost no sanding needed afterward. For the price, the 1-1/4" bore fit perfectly on my setup, and the inserts took all the guesswork out of rabbeting.
