What Customers Are Saying
Most customers praise these bits for sharp performance, clean drilling in wood and metal, and excellent value. However, many report sudden breakage under light pressure or in harder materials, with bits snapping or shattering unexpectedly—sometimes on first use. Some note brittleness in impact drills, while a few mention they lack strength compared to competing brands. Despite durability concerns for some users, those without breakage issues find them reliable and affordable, making them a worthwhile purchase for light to moderate tasks.

Long, brittle bits. Use only in drill press.
Would Not RecommendThey broke very easily when used in a hand drill. Might work okay in a drill press. They cost little and still provided decent value.
