Needed to drill some holes in acrylic and it handled it with no problem on my drill press. I needed it to be exact and the point helped with placement.

I got the 5pcs Set of drill bits. The packaging is labeled with fractional inches for each bit, but the bits themselves are labeled with their metric sizes. The actual measurements of each bit averaged about 0.07mm undersized, so the holes are just a bit snug, which I find to be ideal. Other bit sets I've used in this price range (less than $15 at the time of this review) have been much less accurate in their sizingThe brad points on the bits make it easy to center each hole, especially if a center punch is used to mark the location. The carbide steel is holding up well and staying sharp so far, though I am not making heavy use of these bits. The aggressive forward sweep of the cutting edge makes for fast drilling, but can lead the bit to wander a bit when using a hand-held drill in tight wood grain. In a drill press, these can go all day.I did have to take one star off, because the 5mm bit is slightly out of round on the shank, so I have to take extra care when chucking the bit. It only cost them one star, though, because a slight reorientation of the bit to avoid catching the flat spot on the shank with the jaw of the chuck does still allow the bit to be properly centered.

These bits are great, smooth while drilling, and they feel sharp. They do the job really well, I did not notice any wandering when making contact with the pieces. They seem to be marked with metric sizes, but the case is marked in 'Freedom Fractions', which is not a big deal for me, but may be for some. I used one for testing marked '6' (6mm I assume) which was kept in the 15/64 slot (basically the same thing, 6mm converts to .236 inches and 15/64 divides to .234 inches, more than close enough for me, but worth noting for those chasing the thousandths).The bits arrive in a surprisingly sturdy plastic case that seems to be intended for their long term residence. It opens up in a clam shell fashion to allow for easy removal and insertion of the bits (some caution is advised on reinsertion as these things are pretty sharp). A closeup look at the tips of the bits will show that they are decently sharp and the machining is pretty clean (there are some slight tool marks that can be seen in the closeup picture of the tips of two bits) but the brad points are centered and nicely machined.When chucked up into my classic (and still astoundingly precise) 1947 Delta DP220 drill press (picture of the 6mm bit in the chuck is included for the DP220 fans out there), it produced some very nice clean holes (they look ragged on entrance and exit because I did not clean them up for transparency sake) but the holes themselves are very round and pretty clean. Two seconds with a chamfer bit would make them very nice. The two types of wood are red oak and poplar, and it cut through both like butter. I made a shallow hole to show the profile it leaves in a blind hole and the other two are all the way through the pieces. Also uploaded a picture of the exit holes (the picture with only 1 hole in each piece of wood). I am very pleased with the set and look forward to my next project when I can reach past my old spade bits for these little gems.
