Durable, double-plated diamond-coated drill bits offer more grinding surface than any other bit, resulting in an extended grinding life and shortened working time.

What we have to say about the product
Not a key item but very nice to have for the copper foil method.
Top bits are for grinding small indented pieces that a regular bit is too wide to fit. We always suggest our students have one on hand. You can avoid needing one of these if you always plan your designs around the size of bit you have. (That’s very difficult..)
