Why Choose Busch Fig. 413 Burs?

The secret to a secure stone setting is a perfectly flat, square seat. If your bur wobbles or cuts unevenly, your gemstones will sit tilted, leaving them vulnerable to chipping or falling out.

Busch FIG 413 burs are engineered with perfectly centered shafts. This concentricity means zero run-out (wobble) at high speeds. Whether you are setting delicate diamonds in platinum or working with soft gold, these burs peel away metal cleanly rather than grabbing or tearing it.

Bench Pro-Tip: Always use a high-quality lubricant (like Lube-Stik or beeswax) and work in small, incremental sizes to gradually match the stone’s girdle. This prevents heat buildup, preserves your bur's cutting edge, and ensures a snug, snap-in fit.
