Customer Reviews (4.6 / 5 · 5 reviews)

Carter R. ★★★★★

Finally, a set where the pilots actually fit snug and don't wobble during use. The 3/8" shank holder feels solid, and the range from 5/16 to 5/8 covers the sizes I need most for spot facing jobs.

Lily Q. ★★★★★

After fighting with loose pilots on cheaper sets, I was relieved to see how snug these 14 pilots fit into the counterbores. The 5/8" counterbore took a clean, chatter-free spot face on some steel plate without needing a second pass.

Samuel ★★★★★

The 3/8" shank holder fits my drill press chuck perfectly, and having six counterbore sizes in one kit means I stopped swapping tools mid-job. The pilots are snug enough that they don't wobble, which made my spot facing come out noticeably cleaner than my old single-size setup.
