Busch burs are the most trusted name in jewelers' burs, known for precision and durability, and this Busch Mixed Shapes Student Bur Kit of 23 pieces brings those shapes together in a single, budget-friendly starter set. The kit is part of the GIA graduate jeweler program, with burs selected by GIA expert instructors to align with the GIA curriculum, making it a practical choice for students and emerging jewelers building a first professional toolkit.
