XINGYHENG 20pcs PCB Print Circuit Board Carbide Tungsten Steel Micro Drill Bits Set Shank 0.10mm to 1.0mm and 1.1mm to 2.0mm (1 Each)

Very often, in our industry, we need to drill tiny holes in different materials. I have used these carefully, and find that they do a great job! Like many tiny drill bits, they WILL break if you exert too much pressure on them, or twist them to the side when you are drilling. If you are cautious, they will last a long time and get the job done.

The only complaint is that they are on the fragile side. So, go easy with them.

Work great and great price,1st time using them, works great with dremel stand. Will order more and 0.10mm to 0.2mm bits are very fragile so take your time handling them.

Drills are delicate. They work but need to be very gentle when using them. Broke two slready.

Perfect. Exactly what I needed. But be careful they are very fine and easily broken if too much force is used.

Updated review 4/7/18: i had two bits break in an instant when i uses them for the first time today. Grrrrr. Old review:These bits are so much easier to use with their large shafts. I had difficulty inserting my small drill bits in to the drill bit this is so much easier. I only wish the size was printed somewhere on the bit..... or there was a guide to what color corresponds to what size.....

While these bits work fast and have good bite, they are incredibly fragile, with even the slightest deviation from center (or sometimes just trying to get tie bit out) causing the bit to break. Not bend, BREAK, meaning that you know have a tiny bit of drill bit stuck in the hole you were trying to make.

Bien !

I bought it to drill small holes in plastic (miniature figures). Drills quite well, without effort. You don't need to apply a lot of pressure, which is good for small parts. For best results, I recommend using it with a mini hand drill. All shanks measure 3mm in diameter.

I’ve had various drill bits over my hobby years but these are the best ones I’ve had! They fit snugly into most drill handles, though I would advise to check yours can take 3.2mm chucks. They drill so effortlessly which is great when i’m sitting and magnetising a whole bunch of arms or drilling barrels! I mainly use the 1.2mm through to the 1.6mm bits. The ones under 1mm you will have to be very careful as while they are carbide steel, the slightest excessive movement could snap the bits. The ones above 1mm look a lot sturdier but still be careful! Each bit is colour coded and you can faintly see the size etched onto the metal. The case they come in also folds out slightly so you can stand it in your hobby space while you work. Solid purchase for anyone who drills tiny holes for barrels and smaller arms.

Ich benutze sie in einer 3018 cnc fräse und nur für PCP Platten, was soll ich sagen... Sie machen Löcher. Sehr Umfangreich und gut verarbeitet.

Having been disappointed with so many types of micro drills (blunt, snapping etc) I am really pleased with these, very sharp & sturdy!
