20 Pcs 1/8 Inch Shank Expanding Hole Diamond Burr Bead Reamer Kits

very good collections of different sizes. I used these to clean out stuck grout between tiles and it worked perfectly.

Nice diamond bits. Well made, however not very durable when used on heavy duty projects that require long use for prolonged time. Usually figure for the co$t these are fairly disposable, ok value, they will work, but wear out fairly quickly.

Perfect for my Dremel. I do a lot of bead work making jewelry using precious stone and semi precious stone sometimes the beads come, and there is no hole or the holes are not big enough and so I have to hollow them out going very slowly and that requires a lot of patience and the perfect bit. These bits have been a godsend. The hollow it out does as much as I need to. They work very well with beeswax based lubrication for engraving as well as water I have beat up. I have handled them many times trying to push the limits and they keep cutting perfect every single time. I would highly recommend these bits for anyone doing stonework or needs Bits for their Dremel tool where diamond bits are required.

Very strong, durable bits for drilling holes for beads. Versatile, very sharp, perfect size and great value for your money. Perfect size.

Works well, worth the money, Good product.

These are perfect for drilling holes in shells. I attach to my drummel and they’re really good quality. It takes a long time for them to start dulling. I tried small pilot hole bits on my drill and they just weren’t working, but these are really tough and make the smallest holes through really thick shells.

Very handy to add to your miniature tool collection

Don’t purchase, not worth the bother!
