7 Pack Countersink Drill Bits Set, Wood Drill Countersink Counterbore 3in1, Three 82-Degree Chamfer Cutters, M2 Counterbore Cutting Depth Adjustable, with 2 Allen Wrenches and 1/4” Hex Shank

Works perfectly

Good quality. Much better than those I purchased at Harbor Freight, which I had to return. These were the same price, but they worked as expected.

This countersink drill set is okay for occasional homeowner use. A positive is that the set contains seven different bit sizes to accommodate all standard screw sizes from #4 to #16. The set would be much better if the drill bits had a flat side for the tightening screw to have more contact with the bit. My main complaint is the countersinks are all the same size--they should be different for the different size screw heads. The case is too flimsy and does not secure the bits firmly. I would say the set meets most of my requirements at this price point.

Great for wood- heats up quickly with repetitive use, and I wouldn't use it for metal.

Good quality and reasonable durability and price

Very pleased. Especially for the price. At this price I can afford to buy a whole new set if I break a bit off.

Bought these to add to my collection of woodworking tools. Seem to cut very well. Durable, well made. Sizes are good.

Fair quality. The countersink is fine, but one of the drill bits broke in half the first time I used it in plywood. Consider it appropriate for occasional use.
