Customer Reviews (4.6 / 5 · 5 reviews)

Harper H. ★★★★★

Used a 1/8" double-ended bit for some tight pocketing in aluminum and it held up surprisingly well through several passes. The cut finish was clean with no grabbing or chatter.

Lily ★★★★★

The medium-high helix angle cuts through aluminum like butter, and the 4-flute design leaves a clean finish on tiny slots. I’ve used these for engraving small parts and they hold an edge longer than I expected for the price.

Riley ★★★★★

The double-ended design is a lifesaver for my small pocketing jobs—I flip it over instead of swapping tools mid-run. That medium-high helix really does make a cleaner shear cut than the standard end mills I used before.
