  • Yus, Quality
Quality countersinks, great value for the money. Far better than other brands. I've already tried it on wood and aluminum, great consistent funnel shaped counters .

  • This drill set effortlessly performs on woods, no shredding, clean cuts and light effort required.
This Countersink drill set performs well on soft pine, hard hickory and plywood. I have used it on rubberlike stoppers and got even cutting and very minimal tearing at the top edge.
