Customer Reviews (4.6 / 5 · 5 reviews)

Zoe A. ★★★★★

I was surprised how cleanly it cut through a piece of oak, even when I was doing an undercut for a large letter. The 1/4″ slot came out perfectly smooth, no chattering at all.

Grace ★★★★★

That AstraHP coating makes a real difference—this bit sliced through hard maple for some decorative letter undercutting and stayed sharp the whole time. The 1/4″ slot cut cleanly without any burning, and it left such a smooth finish I barely needed to sand.

Penelope ★★★★★

Made a few test passes in some scrap oak before committing to the real project—the AstraHP coating really helps this bit glide through without gumming up. Clean, crisp edges on the undercut too.
