These work well in the drill press. Nice cutting, you have to go slow and careful to not over cut and get good smooth results.

I don't build cabinets for a living, so these are as heavy duty as I need. Arrived very quickly, have enough steel content that they stick to a magnetic holder and they work very well. I like that these have a hex shank for quick release. Plan on buying another set once I lose these. Highly recommended.

As usual Amazon sold me a great quality product at a very good, affordable price. Also delivery was super fast. The only problem was as usual the delivery driver didn't follow the delivery instructions and come to my apartment door. He or she was too lazy to come to my door and left my package in the front doorway where it could of been stolen. Amazon themselves are awesome! The majority of delivery drivers however are either too stupid to read the delivery instructions most times or too lazy to walk to the door and deliver the package properly...

Cutting edges very poorly ground. To get a countersink was a process of wearing through the material (Baltic birch plywood) rather than cutting. Garbage.

Works good on steel, aluminum and plastic so far.

Not very sharp. It worked better after I sharpen myself. To get a clean countersink on wood, it helps to run these bits with your drill on reverse at low RPM (slow speed) at first. Then, you can proceed to cut in "forward" direction. The price was right, so you get what you pay for.
