Disappointing
Purchased these to drill some Sea Glass. Metal was to soft and bits kept breaking. Using a Drumell in a stand, & in water.Ones that didn’t break would only drill a couple of holes before getting to dull.

Tiny bits.
I thought they would be longer. I dont even know if I have the correct part to put it in for use. I dont believe I will be buying these again.

Bit broke with first use.
The drill bit broke off inside a small shell on the first use. It went dull really fast which is suprising since it's supposed to be diamond crusted. Other bits from other manufactures lasted much longer. This is the first bit that's broken, so there's something with this manufacturer.
