Diamond Grinding Burr Bit Set 20Pcs Rotary Tool Accessories Stone Carving Burr Set with 1/8" Shank for Stone Ceramic Glass Carving Engraving Grinding Polishing

Hakkin 43PCS Diamond Rotary Burr SetThe Hakkin burr set comes in a deceptively small plastic case jam-packed with quite a variety of diamond burrs, diamond cut off wheels and 80 grit sanding drums.The sanding drums are of the “Flap Wheel” type with overlapping pieces forming a sort of impeller shape. The advantage of these being that, as they wear the outer part of the pieces goes and exposes fresh sanding edges making the drum last a bit longer.Hakkin recommends limiting the speed of these tools to 2000rpm and to use water to lubricate the diamond burrs and prevent overheating. Using water on the drums would not be a good idea because they would probably become unglued and fall apart.The shafts of these burrs are approximately 3mm diameter and will fit most rotary tools with a collet type chuck as well as most tools with 3 jaw chucks.I have tried some of the different diamond burrs, a sanding drum and one of the 20mm diamond cut off wheels. All of the burrs and the cut off wheel fits nicely in my small drill/sander and spin concentrically. The sanding drum I chose to try had the mounting hole drilled well off centre, consequently I had to use it at a slower speed than I would have liked but it still performed okay. Looking at the rest of the sanding drums, I could see that most don’t seem to have the hole drilled in the centre and a couple look like, whoever drilled them, had several goes before deciding where to put the hole. In any case and because of where these drums are likely to be used, having the hole in the wrong place probably isn’t that important and they are still useable.Twelve pounds is very reasonable for the range and quantity you get in this set so I am happy to recommend it but only 4 stars because of the sanding drums.

The media could not be loaded.  This is a nice little set of Dremel-compatible rotary grinding heads. There are two sizes of cutting wheel, as many different metal diamond bur heads as you could probably wish for, and five large and five smaller sanding barrels. You have to take care which direction you instal the barrels as for smooth grining, the leaves should go in the direction of the turn and not against it (see diagram on product page). The whole set works very well with my cordless Dremel 7300 and are easy to take on and off using a mini spanner to loosen the chuck. I think that the current Price of £12.09 is excellent value for all of this, and it comes in a nice little plastic tray with snap locking plastic catch for storage, which also has a hanging eye at one end.

This is a brilliant value set of drill accessories.I tested them on some glass as soon as they arrived, and they worked an absolute treat. They've been well made, thankfully. I've tried so many unbranded drill accessories that were dreadful: drills that don't drill through anything; chucks that hold the drill bit at an angle; buffing cloths that are more abrasive than buffy... but these are sound.I've also tried using them to sand some burrs off of some 3D printed doohickeys and, needless to say, it took the unwanted bits off in nanoseconds.At £12.09, too, it's a good price. It's always worth getting the official Dremel stuff if possible but, in a pinch, this is a very decent second tier option.

These fit my dremel-multi perfectlyThere are 43 pieces in the set and everything fits in a little sturdy box.The sand drums are excellent as they are flap wheel type meaning that they wear down and not off.There are 3 holder type shafts. 2 are for the cutting discs and one for the sanding drums.The sanding shaft is threaded so you can screw the drums on rather than having to trust to friction to hold them on.You can screw on the drums from either end so they will work either clockwise or anticlockwise depending how you have put them on.You get 5 large and 5 small sand drums.2 large, two small cutting wheels.The shafts for these have cross head type screws so you are going to need a small cross head screw driver to get the discs on.The engraving heads are a good variety.There is only one fine pointed (seen in the pic where it is fitted to my dremel).You dont get the chuck with the kit, that came with my dremel.Theres one narrow engraving rod and then 2s or 4s of the others (all pictured in the black and white pic)This is a good set for the money.

This set is supplied in a plastic case for storage and to keep it together. It is designed to work with Dremel style multi-tools for engraving and smoothing glass and ceramics. It consists of the following; 3 x12mm - 5pcs, 3 x15mm - 5pcs, 3x6mm - 5pcs, 3x8mm - 5pcs, Sanding drums - 3x6mm(Grit 60) - 2pcs,3x8mm(Grit 60) - 2pcs, T shape - 3x6mm(Grit 60) - 4pcs, Fine - 3x6mm - 6pcs, Needle - 2pcs, Diamond Disk - 20mm - 2pcs, 30mm - 2pcs, connecting rods - 2pcs.There is a good selection which should cover most needs. I have only smoothed off some rough tiles but they seem to work well. Just keep the speed down and add water to keep them cool and minimise dust. This set is great value for the variety of bits included for around £12 and delivered swiftly via Amazon.

This is a good set of burrs at a reasonable price. There is a good selection of tools and they fit my Dremel copy rotary tool well.I have used these tools on wood, metal, plastics and glass and have so far found them to be effective at grinding and very durable. The flap disc style sanders are so much better than the normal tube type of sander I have previously used as they do not seem to wear out anywhere near as quickly.Overall this seems to be a durable and good value set.

I am surprised by how many different bits that comes in the box. There are even two sizes of polishing sanding paper? I am no expert but my husband tried it with his small grinder and they are shape and sturdy. The diamond disc can cut through almost anything.These bits will be very handy for your DIY project that needs a precision touch, as they are all quite small in size. All well-laid out in a box, keeping them nice and tidy.
