    I ordered two sets of these as they were at such a good price. Delivery service good as before even over the Christmas / New Year period... 21 days total !. Diamond quantity very good... inside tube and out so they are obviously wet dipped. The only critisism I have is that they are not size marked so careful selection is needed and several bits have "lumps" of diamonds which will cause errors in finished hole size. Some slight signs of surface rusting too on the tube inside walls as shown on the pictures Im uploading, but overall well worth the cost. Thanks again banggood

    It is a must-have hole drill bit set if you like DIY. Easy to use, it is easy to cut or punch a hole into wood or plastic materials. The bits are made from good quality metal. Very recommended!

    Cheap but only used on wood by me, so they work fine. Cut VERY close to correct size. In a piece of VERY hard balsa used for testing, no hole was more than 0.05 larger than the drill bit. Checked with a high quality vernier set. They do rip a little at the start, but the drills actually clean up after themselves and leave a very nice ROUND hole. IMPRESSIVE for such cheaply made and sold bits. This level of quality is fine for my needs, but I have no idea how they will go if used to cut metals or glass

    The business end looks competent, the bodies are flimsy and one of the bits already started flaking (bottom left in the picture). I'm not complaining at this price point.
