Lucy ★★★★★

I’ve used this in a Leigh jig on oak and walnut, and the 8° angle gives tight, clean joints every time. The 7/16″ diameter handles both sides of the cut without any chatter, even at full depth. Only wish it came with a spare bearing, but it’s held up well so far.

Harper J. ★★★★★

The 7/16-inch diameter cut through some hard maple like butter, and the 8° angle produced tight, clean joints on my first test. Perfect fit in my Leigh jig with zero slop.

Daniel K. ★★★★★

I had been struggling with inconsistent dovetail joints until I swapped to this 8° bit. The 7/16-inch diameter cut through maple without any tear-out.
