SE 30-Piece Set of Titanium-Coated Diamond Burrs, Grits 120-150 - 82331TF

Tiny dynamos, this set of diamond burs really works, and so far as I can tell, really is diamond. I didn't expect anything else, but I had to test it to be sure. I wanted such a set for occasional fine work on very hard items like tool steel and rock.Pros* Perfect fit (diameter = 0.122 in.) for my Dremel multitool* These burs will grind anything -- masonry nails, titanium nitride coating on drill bits, tungsten carbide bit tips, you name it* They do not self-destruct on usage* The set contains a huge variety of shapes (spindles, barrels, balls, needle tips, concave and convex angles, etc.)* The set is safe in a surprisingly nice case insert -- I like that it's a soft foam, cut to securely hold the bitsCons* None discoveredOther thoughtsThe product photo shows these looking more like titanium nitride-coated bits, but they're actually silvery in appearance, and given that they are able etch and cut the hardest, most durable things in my tool collection, I'm inclined to believe they're the real deal, but at an exceptionally affordable price.

I have started a new hobby of cutting the heads, hands and other things off of porcelain figurines and swapping them around to make new figurines. Think that bad boy neighbor in Toy Story but grown up and with a bit of class. Anyway, I needed bits that would allow me to get into small places to cut, sand and alter. These are just what was needed and they work perfectly for me. The porcelain is tough on the bits and I definitely need to use water constantly, but if I'm a bit careful they last a good long bit. I do less cutting with these and more of the fine filing so these are holding up well and there is always one in the set that's perfect for the detailed job at hand.

Okay so I fully expected these things to shatter on contact with any given surface, but instead?I'm new to the gig, so of course I do things my own way. This is what people who are professionals like to call "the wrong way" because I'm hardheaded. To my surprise so are these! Without using water, without keeping an eye on temperature, without even putting them in right these things have lasted and lasted. I carve rocks for my Etsy, so I put the machine on full speed, ignore all manuals, and becomes extremely stupid for short periods in which I slowly remove my safety gear in order to see better.I snapped two, under pressure, not properly tightened, without water or any lubrication, at top speed. Two.The other 28 pieces are still going strong after oh, what, drilling through about 20 stones from my backyard on top of carving the face of like 10 others and more objects than that in general? And I haven't even used all of them since I tend to just need direct drilling or etching but heck, they work on stone considering I tested them all the first time I touched them to see what worked doing what. It's handled some stones with mica chips, some gabbro (granite), one piece of fool's gold, other unidentified hard stuff, sandstone (by far the easiest), and even quartz (which explodes with lightning internally, it's so cool, but it eats blades like crazy not these though!). They stand up to being tilted in directions they really should not be bent (You know better self!) and even wriggling them in the hole I've created. They still carve perfect little details, although I have to admit they are wider than I'd like. But that's by design so what, am I going to blame people for making what they say they will? How about no.The container is the crappiest thing you'll ever see by far, but you're likely buying these for the bits. This is extremely cheap, but wow. Wood, Bone, Stone, anything I get a hold on seems to be no problem. I've even done soft leather with fur on, and glow in the dark plastic. I've carved my name into everything I can get my hands on, used them to clean off soda cans, and engrave them. I've used them to cut composition books, admittedly real drill tips do better but I like to rebind mine for long life and I try them on anything out of a sick sense of curiosity. I've used them on everything and they just cheerfully keep cutting even though it's clear I should have broken or dulled them with my outright mistreatment.Good bits. Best bits.

This is a super-budget bit set and is absolutely worth the price. These are not "keep for a lifetime" bits - they will wear out quickly. I have been using these to remove sanded grout from a tile floor and they have proved a much better value than the Dremel 1/16" grout bit (which breaks in minutes and costs as much as this whole set). The assortment of bit sizes is handy for getting into tight spaces and for deburring. Five star value. Three star quality. Five star functionality. I will definitely be buying another set for my next project.

First of all, it's not full-sized, but I've read older reviews so I knew what to expect. I've worked with a keyboard this size before on a Asus Netbook. The Enter key is if too small for my liking.The keys are a soft with just enough travel and a slight click that I like. They are brightly illuminated which solves the problem I brought it for in the first place.It is sturdy. It feels and looks well-made.I think it good value for money even with the negatives.

best set I have gotten yet. I did notice that they are a range of grit as I believe was listed however it does not say on the bits or on the package which is which, so if you were not paying attention or realize that they are different grits or heck some people probably don't actually know what that means, you would think that the quality between each bit is inconsistent. which it is but its supposed to be. long and short of it the only recommendation I have is to figure out a way to mark the grits, I dunno dip the shafts in diff color enamel or something, that's what i did.
