Used them to drill pilot holes in door hinge mortises, easy to use, good results. Seem well made.

The bits dull overtime, but it is replaceable.

Several of the drill bit shafts are slightly bent causing the drill to wobble. As note in other reviews, the spring loaded centering shaft sticks on all the bits. It's the typical low quality Chinese product.

I actually bought these to use to extract broken bolts. I change out the bit to a left hand threaded bit. The spring loaded holder keeps the bit from walking while you are drilling it out. Super cool love them. Oh the work great for their intended purpose too!

Excellent range of sizes. The bits and guides work smoothly. Make sure to tighten the drill bits before you use them for the first time.

Fit and finish is what I'd expect at this price point. My only real complaint is the lack of quality control regarding the drill bits (specifically the 1/4" installed bit and its spare). Both bits have pronounced metal burrs on the trailing edge of their end grind (see pictures of installed bit, spare was the same). The rest of the bits were clean and serviceable (I didn't check them for uniform grind angles as these are just for use in wood and for my use just for hinges - a few thousands here or there will not matter - if these were for steel it would be a different matter).So if you can tolerate the minor inconvenience of cleaning up the end grinds with a pic tool or other such instrument to remove the grind burr, then these are fairly serviceable centering bits.

Feels kind of cheap, but you get what you pay for. Good for occasional use around the house.
