Customer Reviews (4.0 / 5 · 5 reviews)

Emma K. ★★★★★

The 1/4" shank fits my drill chuck perfectly, so no wobble. It leaves a clean, burr-free hole in aluminum every time. Exactly what I needed for deburring those plate edges.

Evelyn ★★★★☆

The 1/4" shank fits my drill chuck perfectly, and the 82-degree angle is spot-on for #8 flat head screws. Cuts cleanly in steel without chatter, though I did need a light oil for the best finish.

Owen ★★★★☆

The 1/4" shank fits my drill chuck perfectly, and it leaves a clean seat for flat head screws in brass. Only wish the smaller sizes were available individually instead of buying a set.
