The short length is intentional — pavé holes are relatively shallow, and longer drills are prone to breaking under torsional stress. The 2-groove design actively expels material from the hole during drilling, extending drill life and maintaining accuracy.\u003c\/p\u003e\u003cp\u003eDeveloped through a partnership between Busch of Germany and the world's finest micro-diamond setters, these drills are the trusted solution for professionals who set stones for leading jewelry houses.
