Would Not RecommendFirst the hex Chuck adapter came off; fortunately it still works without it. Then the tip of the bit broke off. I was able to grind the point down so it still works. Only saving grace is that you can swap the countersink part over to another bit.

Nice set for almost any size screw
Would RecommendWhat I like: 3 bits to accommodate most typical screw sizes, Adjustable collar to adjust depth of plunge, Replaceable bits, Affordable price. What I don't like: Countersink heads do wear out, and work best on softer woods and composites.

Not very durable. After setup and tightening the set screw, the bit still came loose with light duty usage.

Drilled well but came apart. The allen set screw let’s you put bits in, but this bad boy fell apart with the reamer coming from of the shaft. No way to taste it back n
