BicycleStoreSelf Centering Drill Bit Set, Hex Shank Self Center Hinge Drill Bits Tool for Woodworking Window Door Hinge with 1 Hex Key and 8 Drill Bits (Colorful 9PCS)

I was able to drill centered holes as I needed to.

They will work (SORT OF) Some of the drill bits is off center. You get what you pay for. Worked as, and in construction/machine shops for over 50 years I would absolutely not recommend, unless this was the very last resort.

I had to bevel the tips so they would stay in the screw slots!

Nice for the money. Don't expect a $100 set and you'll be fine. I do wish there was a bit more of a taper on the shafts. I got the 17pc set and the extra bits that came with it are much better than the ones that come installed. Those are basic HSS and the extras ones are gold oxide.

While I liked the appearance/color coded aspect of the bits, they just failed mechanically. No real bevel to seat, many of the center holes were actually off-centered (defeats the point of the product), no way to set depth (really weird springs supplied). I recieved, inspected for quality and ultimately returned item without actually using. I can't recommend this set.

Replaced the bits with some for drilling metal and used to drill out broken off screws in a metal bracket.

Lots of play in them. Wouldn’t have required much effort to bevel the top would buy something else. Great idea loved the color coding but wish they took a bit more effort in making them

Le produit est conforme et a été livré comme prévu.

Quality was good. The smallest drill was a little stiff. I like the colour code. It makes it easier to remember which bit to use. The bits look sharp and may last a long time.

The original package of the tools is broken, the tools are good and working properly. Please improve your packaging process.

I got these BicycleStore 17PCs Self Centering Drill Bit Set as my original bits came with the drilling machine were getting spent.The quality of the product is just fine. You get what you pay for. These come with 1 Hex Key, 8 Drill Bits 5/64'' 7/64'' 9/64'' 11/64'' 13/64'' 5mm 1/4'

Very weak spring action and no taper on head. A tool for occasional use at best.
