Robert ★★★★★

The AstraHP coating really holds up—I ran it through some tough aluminum and the 1/2" tip came out clean with zero chip-out on my edges. The 1-inch cut length gave me the depth I needed without any extra passes, and it's held its edge far longer than my last bit.

Kevin ★★★★★

The 1-inch cut depth cleared my walnut pockets in one pass without any chatter, and the AstraHP coating kept the flutes from gumming up even on softer pine. It's a solid step up from my old HSS bits for aluminum too—the edge held true after a full sheet of 6061.

Claire N. ★★★★★

The 1/2″ cutting tip and full 1″ length of cut handled my aluminum job without any chatter, and the AstraHP coating kept the flute clear the whole pass. I've already ordered a second one for the next project.
