10PCS 2.5mm Twist Drill Bits,Micro HSS Cobalt Metric Spiral Rotary Tool

They are drill bits. They work. Some of the small metal cutting disc's for dremel type tools come with a very tiny center hole and mount on the shafts with a very tiny screw . There are shafts that have a bigger screw with a wider shoulder and washer that add much better support to help keep the disc's from shattering. To use the larger screw , the disc hole needs to be drilled to 3mm .These bits work perfect for that purpose. Very happy purchase.

I had a small project that needed a drill bit of this size. Great eBay Seller, Very Fast Shipping, Excellent Auction Items! Thank you, all A+++++ here!

Yeah the headline is a bit of an exaggeration, but boy these bits are absolutely horrible. I bought these for the new Blum tandem jig I got. I never replaced the bit on the old jig, and I don’t know how many thousands of holes the old bits have bored, and it still only requires light pressure to drill holes. This new bit requires tremendous force to drill a 2.5 millimeter hole in poplar. How it that possible? I can use a thumbtack with a fraction of the force. Needless to say these bits went in the trash, and new ones are on the way from a different company. I seriously can’t get over how hard it was to drill such tiny holes. I go through a couple hundred thousand screws a year in my company. Many of these screws require pilot holes so I’m very familiar with the characteristics of drill bits. If you need 2.5mm bits please look elsewhere.

Muy buen producto

Being a boat modeler you need all kinds of tools and need to know where to get them. There is enough in this order to last a lng time

the size was right, as well as the price

Works great. I am using it in a dremel tool

Absolutely the worst drill bits I’ve ever bought. Got them to drill into brass a very soft metal couldn’t do it at all and I tried a few of them. Tried wood as well to see if maybe there are not for metal despite saying for metal as well but also are terrible at drilling into wood. I’m betting they are selling these knowing this assuming no one will return it because it would be more in gas to drive it to the post office than the value of the bits. Amazon needs to remove garbage like these from the site

Die Länge der Schneiden beträgt nichtmal 1/3 des Bohrers. Zudem wirken die Bohrer stumpf. Hat meiner Meinung nach nichts mit der Abbildung gemeinsam. Gehen zurück. Keine Kaufempfehlung.

以前、似たような金額でインパクトドライバー用のドリルビットを購入しました。 しかし、これが見事な粗悪品で、インパクトドライバーに装着して、トリガーを引き、先端を観察すると 中心から綺麗に回転してなく、結果、全く孔を開けることが出来ませんでした。 通常のドリルも持っていたのでチャックで使えるこの商品を購入。 回転もしっかりとセンターが出ていて、また、孔開けも普通に孔が開きました。 購入して、ゴミ！と言う事はありませんでした。

Absolut ungeeignet um normalen Baustahl zu bohren !!!

Versand war schnell. Bohrer wie erwartet bei Bosch Professional

tres bon produit pour le prix
