Customer Reviews (4.8 / 5 · 5 reviews)

Aurora R. ★★★★★

I needed a clean mortise for some cabinet hinges, and this bit left zero fuzz along the edges—the 1/2-inch shank kept it steady even at full depth.

William ★★★★★

The carbide edges on this bit are holding up beautifully through a full cabinet build, and the 1/2-inch shank gives it zero chatter even in dense oak. Cuts are glass-smooth with no burn marks, so I don't have to sand as much afterward.

Mia I. ★★★★★

I was able to route a perfectly smooth dado in some hard maple without any burning, thanks to the sharp carbide tips on this 7/8-inch bit. The 1-1/4 inch cutting depth handled my pass in one go.
