The short length is intentional — pavé holes are relatively shallow, and longer drills are prone to breakage under torsional stress. These drills deliver the control and reliability that exacting stone-setting work demands.\u003c\/p\u003e\u003cp\u003eDeveloped through a partnership between Busch of Germany and the world's finest micro-diamond setters, the 4205S series has become the go-to solution for what was once a drill-breaking nightmare. These carbide twist drills are trusted by setters working for the most prestigious jewelry names in the industry.\u003c\/p\u003e\u003cp\u003eThe 2-groove design actively expels material from the hole during drilling, reducing heat buildup and extending drill life.
