Broke on 3rd hole
Would Not RecommendI drilled 2 holes in a board and on the third hole, the hex shank spun off the bit and made it worthless. I was very disappointed as I only bought one and had to drive 30 minutes one way to get a different brand. This delayed my project which was frustrating.

Poor quality
Would Not RecommendThis bit strips out where the hex shaft and bit attach and comes apart. The tip breaks easily as well. Other brands I have used don't do that.

Reasonably priced and works right.
Would RecommendInexpensive self centering 5/64 drill bit. Great for pre-drilling a flat head small wood screw.

All 7 pcs are defected. They will trembling when using. Your website can only upload picture, but I have one video on hand if you want to see it for reference. Also, it's not friendly for the return. Cannot get any label or barcode till over ten times try.

Check screw drill recommendations
Would RecommendI should have had a smaller dia bit for the drawer glides screws. Bit depth a little short. Fair price

It works but...
Would Not RecommendThe spring in this is so strong that it's difficult to push down while holding the bit and part in position. It wants to move the piece you are drilling the hole for and that defeats the purpose of a self-centering bit.
