Diamond coated drill bit for jewelry making
* Super duty diamond coating on nickel-plated high speed steel will give you excellent results even on semi-precious stones
* New, improved fluteless design brings more diamonds in contact with your material
* USE PLENTY OF WATER as a coolant for extended performance and life.
Note: Common occurance emailed questions I get from users is: My drill bit doesn't fit. Change the collet in the dremel. People get so used to drilling with one size when they change sizes they forget the collet must be changed.
USE PLENTY OF WATER TO KEEP DRILL BIT COOL.
