Customer Reviews (4.8 / 5 · 5 reviews)

Ava T. ★★★★★

Bought these for a few aluminum jobs and the submicron carbide holds an edge noticeably longer than my usual HSS bits. The +.000/-.002 tolerance made slotting more precise than I expected.

Evelyn ★★★★★

The 4-flute geometry really clears chips fast, and the center-cut design makes plunging a breeze. Tolerance of +.000/-.002 meant my parts stayed dead on size across a whole batch.

John B. ★★★★★

The submicron grain carbide is noticeably denser when you touch it, and the 4-flute design clears chips like a dream in my aluminum work. I’ve pushed these through some tough passes and the cutting edges are holding up far better than the cheap sets I used before.
