BeHappy Countersink Drill Bit Set, 5PCS M2 HSS Tapered Wood Countersink Drill Bits #4, 6, 8, 10, 12 Tapered Bit with 1/4" Hex Shank Quick, Allen Wrench, Counter Sinker Drill Bit Set for Woodworking

I like that the chuck holds the hex shaft and not the drill bit.

Tapered bit is a plus. Like the plastic storage container. I would purchase again.

I loved these at first and used them a lot. But they began to break. Especially the smaller ones. Will probably try different brand next time.

This is one of the most used tools in my toolbox. I use them on almost every project I work on. And they have held up very well.

They are great.

Even on soft wood they generate smoke when trying to counter sink

The drill bits are very dull as well as the countersink. Will not buy again. Go with FTG or Powerwolf.
