Jacob ★★★★★ Sep 13, 2026

I was worried about chatter on my drill press, but the single-flute design kept the cut really smooth through a batch of aluminum brackets. The 82° tip leaves a clean chamfer that sits flush with my flat-head screws.

Madison S. ★★★★★ Sep 12, 2026

Cut through mild steel like butter with barely any chatter, which surprised me for the price. The single flute clears chips so well I didn't have to back out mid-hole once. Chamfers came out clean and even on all 12 holes I did today.

I had to try a few speeds to get the chatter completely gone, but once dialed in these cut beautifully. The single-flute design makes a noticeably cleaner hole than my old set.
