Masonry Drill Bit Set KAKOO 10 PCS Tungsten Carbide Tipped Ceramic Tile Drill Bits Assorted Size Twist Drill for Concrete Brick Glass Plastic and Wood

Pin vise clamps bits crooked so they wobble when used.Some of the bits had No angle on the tip, almost like they were broken off. Returning !

after drilling only three (3 ) holes into the slump slump stone block, the bit that I was using for my project completely destroyed itself. The carbide tip and one of the flights broke right off as I was attempting to drill my fourth hole. Not being able to see inside the hole as it was drilling, the hole size was destroyed also. May work fine on plastic though. Ben Di Gaudio

Honestly I am very happy with this purchase. There are plenty of bits here to do some of the smallest holes I could possibly need, however, there is almost no organization. The bits are separated out by size into three Ziploc bags which is OK, but no where near ideal. I would prefer to have a small block of rubber, plastic, elastomer or even wood where the bits were placed into to keep them a bit organized.There are duplicates of each bit, so do not expect to have 50 different bit sizes, at most there are 25 sizes, which in all honesty is a good number considering they range from 0.47mm up to 2.87mm. If they are not duplicates then many of the sizes are difficult to distinguish due to the the sheer number of bits, and this lends to the point that there must be a way to organize them.The handle is a knurled aluminum shaft with a triple cut compression fitting that allows the bits from the smallest to the largest to be handled. The handle fits well within the hand and has a floating palm knob that allows the handle to be turned while applying pressure, but they could have put in a ball bearing instead of the pressure fitting they did, this would allow a much more secure feeling. The creators included a pair of fine tweezers, which is a really good idea since many of the bits are so tiny.All in all I would buy this product again and I am building my own case to hold all of the pieces. Its a good product and I do suggest people get it if they need to make very fine, very small holes.

absolutely the worst chuck on any drill-like tool i've ever seen. it's bad... like, really, really bad. the only redeeming quality is that the jaw center is clean enough to hold the bits... *if* you can get the jaws centered. the threading used to open/close the chuck jaws even feels off and unpleasant to turn, like painted threads rubbing on slightly to deeply cut painted threads.but... it's hella cheap for when you need a lot of really small bits for a project and you have no intention of doing anything even remotely production on it.i am repairing and restoring a hewlett packard robotic tape library, and a couple of the plastic gears inside are cracked, cracking, or snaggletooth. i have managed to find replacement gears in the couple bags of random assorted gears i purchased (you never know when you'll need a random plastic gear at 2:14am, lol) but the l/r synchronize transmission shaft's gear was a bit of an oddity, with the shaft diameter rather large for such a small gear... which is probably why it cracked the way it did. so i found a gear with 12 teeth and a compatible modulus, and shaved 1.6mm from its height and drilled the bore from 0.6mm to 2.8mm and chuffed the bore to fit a knurled drive shaft end.the bits actually cut the (probably) nylon gear! i did have to resort to a dremel with a flex shaft to spin bit fast enough to actually drill, though.these aren't heritable: they don't get their own line in your will ⃰, they'll fall under ”misc. tool like thingies”... but they can be ordered at 9pm and arrive before noontime the following day :)---* now that i think about it, these *will* get their own line, as absurd as i can make it: they must be gold plated and displayed prominently on an alter in the guest bathroom, along with a magnifying glass (also gold plated) and several sets of poorly made tweezers of various geometry (plated gold) and one pair of perfect tweezermans micrographically painted to perfectly match its surrounding. whomever has these on display will get my shop full of tools. up to once per year, these may be stolen by another beneficiary of my will, and their grandure and majesty improved upon, and *if* and only if a supermajority of the beneficiaries of my will, not including the previous owner of these bits, votes that the display *was* improved by theft and the additional aesthetics.

Being this is an inexpensive product, it is adequate.Pros are the collection of drill bits supplied. There are very many sizes in very small increments so you can get a hole just the size you need. Also, a small tweezers is provided which is handy. Plus the shape makes it fairly easy to use well.The con is that the chuck on the handle that holds the bits is not very well machined. It's hard to get the bit, especially the very small ones, centered in the chuck, and quite hard, again especially with the smallest bits, to get the chuck tightened enough to firmly grip the bit.If you only need this for occasional hobby projects, then it should be fine. But if you are going to need it often, I would look for a higher quality version.

The pin vise itself easily cross-threads, it's hollow, so bits fall inside of it, it's hard to center, and overall it's just a bad product. The bits are fine for modelling and you get quite a few of them, so I will probably keep the bits and get a nicer vise.

The tiny drill comes with drill bits that range from a couple of millimeters to fractions of a millimeter. The chuck will hold any of them and is easy to spin with your finger on the end with the bearing and your other fingers and thumb rotating the body with the drill bit. A really tiny hole might tend to wander, especially if you're drilling into something like wood, so you want to START the hole with a pin or needle pushed in where your measurement says it should be. Precision work doesn't need to be done quickly. Sometimes accuracy takes time. It's not as fast as a power tool but the control is much better. This is a nice tool. Most of the drill bits were too large for my needs (building a tiny ship-in-a-bottle) but the smaller bits were just right. Somebody was thinking when they made this kit: it includes tweezers to sort and pick drill bits. Also includes a plastic case that holds everything in one place so you don't lose it!

Anyone doing fine, detailed work will find this a very valuable tool for doing fine work with their hands. The drill bits range right down to very small so if you cannot find the right one for your job I doubt you are going to find it anywhere.

purchased for use when doing 3d printing and electronic projects , ive only had it a few days and used about 4 times with different size bits ,so reserve judgement on quality after using for any lenght of time but at moment its perfect for my requirements easy to use ,bits are sharp (i have seen other reviews saying bits were blunt or broke easy) but in all honesty i've found them sharp and up to the job i require them for, i'll 3d print a stand so easier to store bits and use

This small kit is ideal for model-builders and electronic constructors. A simple hand-drill and a big selection of twist drills from 3mm downwards. I used it to fix a wall-clock, where I needed to carefully drill several holes without damaging the unit. You can't do that with an electric tool, they are just too quick.Using this kit, you can accurately bore holes in delicate parts at exactly the spot you want and to exactly the depth you want. Highly recommended.

Overall quality is ok but not outstanding. If you are buying to do a specific job, you’ll be happy. If this a regular tool, you might want to spend a little more.

OK for the money. Pin vice is OK but the smaller twist bits have no tip machined on them. They have been extremely badly 'sharpened' so they are blunt and wander even on soft plastic. Chinese quality,
