Joseph C. ★★★★★

First time using a coated bit and it really made a difference clearing chips from the mortise. The down shear flute left a clean edge on the top, and the cut felt smooth from start to finish through several test pieces.

Lucy X. ★★★★★

I’ve been cutting a bunch of cabinet door mortises with this bit, and the down shear flute keeps the top edge clean enough that I skip most sanding. The 1/4″ shank held up fine in my plunge router without any wobble, even on deeper passes.

George C. ★★★★★

That short down shear flute makes all the difference—the top edge of my mortises came out clean with zero tear-out on the oak. I've cut about a dozen joints so far and the AstraHP coating is still slick, no burning.
