Natalie E. ★★★★★

Cut rounded slots in aluminum plate with this and the .025 tip left a clean radius with almost no cleanup. The 1/8 shank fit my trim router collet without any wobble. Solid carbide at this size is a nice surprise for the price.

Claire J. ★★★★★

The 4-flute design clears chips way better than the 2-flute bits I used before, so I'm not stopping to blow out the cut every few passes. Ground a nice smooth radius on some walnut trim with the .025 tip and it left almost no cleanup sanding.

Olivia ★★★★★

Bought this for milling rounded slots in a small hobby project and the 1/8 shank fit my trim router collet perfectly. The 4 flutes leave a clean cut even at slow feed rates, though I did have to dial my speed back a bit to avoid chatter.
