Customer feedback highlights clean plywood cutting and useful performance, with some customers reporting a 0.030 depth of cut. Durability is mixed, including reports of bits breaking during use. That trade-off is relevant for a small-diameter bit intended for detailed CNC work, where breakage could interrupt a job. The aggregate ratings lean positive overall, but do not establish why people rated the bits as they did.

Negative themes

Some customers report that the bits break during use.

Mixed feedback

Durability receives mixed feedback.
