George J. ★★★★★

Cutting aluminum engraving lines with this thing and the 4 flutes leave a noticeably cleaner edge than the 2-flute bits I've used. Carbide feels solid in the collet and it hasn't chipped yet after a dozen passes.

Timothy D. ★★★★★

I was worried a .045 cutter would snap on my first pass, but this thing held up through a whole afternoon of engraving aluminum plates. The carbide feels dense and the flutes clear chips well, way better than the cheap set I had before. Runout was basically nothing on my spindle.

Elizabeth ★★★★★

The 4 flutes leave a noticeably cleaner finish on aluminum than the 2-flute bits I used before. Runout on the 1/8 shank is minimal too, so plunge cuts stay accurate. Held up through a full afternoon of milling without any chipping.
