1/2インチ ラビットルータービット × 1/4インチ シャンク – Whiteside 1951（AstraHPコーティング）

Used this to cut a perfect rabbet for a cabinet back and the bit stayed sharp through over forty feet of plywood without any burning. Being able to swap the bearing to change the cut depth is such a handy feature.

The AstraHP coating on this bit really helps the cuts stay clean longer without gumming up. I used it with a 5/8" bearing to get a perfect stopped dado in some oak. Came out of the package sharp and ready to go.

Swapped out the stock bearing for a smaller one I had on hand and the rabbet depth changed exactly as expected, made dialing in a precise dado cut surprisingly simple. The coating on this bit seems to keep the chip buildup minimal compared to my old uncoated one.
