A filling may have come out, part of the tooth may have broken, or a crater-like hole on a tooth may be formed from excessive grinding or clenching of the teeth. No matter the reason, the bottom line is that any hole in a tooth needs dental attention sooner than later." Dr. Andrew B. Jordan
Having come to the conclusion (See my pages on boring small holes) that the only practical way of boring small holes is to use one piece cutters and the only economical way of doing this is to produce them from round high speed steel in the workshop itself, let us consider the requirements.I should though add that at the very smallest sizes grinding by hand will be difficult, but not ...
