I’ve used these on pine and birch plywood, and the 82° angle seats screws flush every time without any tear-out. Cuts smoothly and quickly, no real chatter to speak of.

The single-flute design really does what it promises—no chatter at all on the pine boards I was working with. The 82° angle leaves a crisp, clean seat for the screw heads, which made my final assembly look much tidier than usual.

Cut a dozen holes in some oak today and the 82° angle left every screw head sitting perfectly flush, no tear-out around the edges. The single-flute really does keep it from jumping around, which I wasn’t expecting for the price.
